A 20 x 20 ft 12 inch x 3 inch aluminum flat pan carport canopy structure that is using 7" inch .125 aluminum extruded beams and 3 inch lock seam steel poles with two of the poles in the ground and two are attached to the cement driveway. Built in NW OKC near N.W. 36th and May Ave.
Santa-Fe Trim - Is a aluminum type false pergola ends trim option is also popular trim option for the canopy top with four different false pergola canopy trim on a rolled formed or a SIP panel canopy. There is a Santa-Fe trim option for the canopy top and or the poles and beam set as well.
Attached or Stand-a-lone -Any type of carport canopy structures can be attached or a stand-a-lone type of carport canopy structure. Most are attached because of several building savings reasons. If attached the house structure can act as a set of front legs and makes the structure stronger.
The other reason might because of insurance purposes. If a canopy is attached it is normally treated different then a stand-a-lone type of outdoor structure with a whole different set of insurance protection rules.
Price - What does it cost? We know that price is important to everyone and is a lot more complicated then just saying so much per square foot as each structure may require more or different materials then another which would effect the overall project price. There are way to many building variables and options to consider within any canopy design before we can come to the final price. It is not like concrete that is the same price all the time! These building materials changes all the time as the price are dictated by the market and supply and demand. Each and every structure must stand on its own merits and they can not be thrown into a ball park figure as per price per squire foot or the estimate is going to be way off and someone is not going to happy if the estimates are way off.
Post & Beam Structure -Most types of a carport canopy structure is a form of a post and beam type of structure. All posts should be secured to a approved concrete pear or in some cases it may be securely attached to an existing slab surface or core drill below the surface. With larger posts and beams structures their are longer and wider open areas that require large building materials. Their are also limits to any type of building materials of how far they may safely open span.
Note not all poles are the same. The more secure the structure beams and poles are the stronger the structure may be.Using larger size beams and poles allows for longer span between poles on a average height structure. A structure built higher up in the air may need stronger building framing member such a one for a RV or motorhome.
The taller the structure might be the more updraft winds the structure is going to receive under the structure so the heavier and stronger the structure frame and its canopy covering should be
An RV owners canopy requirements that is 14 ft up in the air so the canopy under structure or frame should be heavier and stronger then a standard 8-10 foot height canopy requirements just because of the wind / snow loads the structure may experience. In Oklahoma we can experience some really strong wind loads during one of high wind events. Any building code requirements is minimal building requirement. A home owner may want to build above the standard building code requirements. The ole saying says "It is better to over build then to under build" - Just in case...
A 20 x 20ft attacked 26 gauged steel flat pan canopy over 2 - .125 or 1/8" inch aluminum beams and 4" inch aluminum poles that are into the ground. Built in Moore OK and exceed there 125 mph wind load requirements. This structure is engineered to handle up to 140 wind loads with its oversized pole and beams. Near SE 104th & Eastern Ave
Extruded Aluminum Pans-are used within a commercial type of "heavy duty" applications. Extruded means that the aluminum was forced though a die to cerate the formed pans. Schools or commercial grade projects normally will use these types pans for there Bus Stop area and there walkway canopies as they are considered to be a lifetime roof system. They are also great for used as a RV canopy that is needs to be higher up in the winds. Pans range from .080 to .125 which is 1/8 thick.
BUILT ON TRUST
A 24 x 20 ft attached basic trim 3" inch thick aluminum structural insulated panel (SIP) carport canopy structure with 7 inch .125 aluminum beams and 3 inch lock seam steel poles that was built on the N.E. side of OKC near N.E 23 rd & I-35 Hwy. Canopy covering the walkway into the porch area.
High Quality Custom Built Carport Canopies
When your ready to do build then let us know so we can talk about what your building requirements might be and what your different options might be when building your carport canopy structure.
Metal (Steel / Aluminum) - Most canopy covering materials are a machined rolled into shape or formed from a steel or aluminum flat stock coil material that are available in numerous different thicknesses and color options or it is extruded by forcing the materials though a die to form a its final shaped finished product. Extruded aluminum products are normally much thicker then rolled formed products. Most are rolled because the process is more economical priced product other then the heavy gauged extruded products. There are limits to how thick of building materials can be rolled into there final shapes and designs.
For more info click on our contact page or call us at:405-246-6821or email us at:Info@abetter
Truss designed roof -A per designed truss roof is available using metal or wood products. In metal we use red iron or galvanized steel products. Truss designs can be engineered as per the project requirements and then there are non engineered trusses depending on the project requirements.
Style -refer to what type of top canopy design. (i.e. flat top, cable roof, lean too, and so on.
Single slope design - Flat or shed type of roof design with a single slope. The roofs - slopes may be front to back or side to side.
Lean too design -Normally tied to an existing structure that is capable of holding the structure up and acting as a set of it poles. A form of a single sloped design but just attached from the side of the canopy.
Cantilever type designs -There are numerous different versions of a cantilever type of canopy structure but the most common is a double cantilever design that has a center type of pole(s) and then the structure is built of equal sizes on both of it sides. Then there are a single cantilever structure which has larger poles just on one side or end of the canopy structure. Requires larger poles and should be deeper into the ground.
Cable or Hip roof design -Double sloped design with and without end caps and/or a finished ceilings. Hip roof design - Double sloped design with a canopy roof hip or a sloped back cable end included.
Poles & Columns - Are one of the most important part of any canopy structure and is the most overlooked part of the structure. The poles hold up the other parts of the structure and does the heavy lifting. All canopy structure snow loads and wind loads are connected to the carport structure beams and its poles so the heavier the poles and the larger the beams are the stronger carport canopy system your going to have. Any code requirement is a minimum building code require and you can choose to build above that minimum standard.
"We do not scamp on frame structure and the poles or the beams" They do all of the heavy lifting!
When the ices and snow loads pile up on top of any canopy it could be a heavy load and any canopy structure would get stressed and with out the use of stronger enough pole the end result is that it could collapse. We also offer a line of decorate aluminum and fiberglass poles that are available for a architectural design options.
It is very important for any home owner to be fully aware of what type of building materials are being used to build there carport canopy structures because we see numerous structures that are built real scratchy at best. When the winds blow or the ice and snow falls is when any canopy structure is going to stressed and be put to the test.
A Better Construction Co dba Carports of Oklahoma customs designs and builds a variety of high quality different types of carport and RV canopy covering structures for numerous different types of residential, commercial and industrial applications.
Commercial Carports - Carports have become a standard feature on many commercial and multi-family properties, and even those buildings without carports have parking lots with space for them. Carports provide users the benefit of shading cars and protecting cars and people from rain and snow. Carports keep cars cool, reducing the power required to air condition them when they’re started, and reduce sun and hail damage to the car finish. Larger versions of the smaller residential carport canopies. These larger structures can be engineered for certification that might be required by city, state regulations or insurance requirements. By using heavier or larger framing members and poles the extra wind and live loads can be increased as needed.
Much like our vehicles painted and polished finish the premiered coating of the red iron steel is just a "temporary" coating and is not a middle nor final paint coating finish. A final painted finish should always be applied to any metal surface. The red iron steel should be painted to protected it from the outdoor weather environments to maintain its appearance.
Solar Carports - Today and because these thin-film flexible modules they can be installed over low-load-capacity roofs that prove challenging for conventional crystalline panels and rack systems because the roofs can’t support the added weight. Today’s flexible modules use a factory-applied butyl-based self-adhesive tape Installed with this simple peel-and-stick adhesive, flexible modules become an integrated part of the roof system and have the same wind uplift and seismic performance characteristics of the roof system itself. From an installer perspective, without racks to assemble, ballast to carry and place, or leak-causing roof penetrations, peel-and-stick thin-film modules are the simplest, fastest and lowest labor cost rooftop solar solution.
Carport Canopy Coverings Materials -
There are various and numerous different type of different styles of canopy structure covering that are available in various different thicknesses and different profile types.
Different manufactures will offer there own unique designs customdesigned rolled panels and pan designs that are unique to that one manufacture and to that one manufacture only. So it is important to know where your building materials originated from in the first place.Just in case...
Types of Carport Structures - Carports are a form of a large "canopy" structures and are used for numerous other and different types of applications such as break area pavilions, foyer entry way, product storage covers, side walk coverings all designed to protect people and/or materials from the weather.
Good wind and seismic performance engineering is vary important to any carport structure design !
Each carport application may have different building specifications and use different building materials depending on the carports design requirements and
its size as well as its open span requirements and
what types of building materials are to be used
within any one carport canopy application. It is important to understand any structural load requirements such as dead load and live load requirements. Dead loads are the weight of the structure itself and live loads it the loads that can be put into the structure such as Wind, Snow and Earth quake loads.
Remember that all building materials has its limits to how they should be safely used and how they can be used to open span between poles. If you exceed the building materials limits the structure could fail while under stress which normally comes during a server weather event. The stress can come from many forms but normally come from wind and snow loads. Snow load refers to the amount of "snow and ice" weight per sq ft that a building's roof is able to support. Wind loads refers the amount of force the winds put on any type of structure and in a canopy type of application we talk about up-drafts and down-drafts winds.
When dealing with a larger clear open span without the use of center poles you must use a building material that is engineered and designed for the purpose it is intended. The larger the canopy structure the larger and heavier the beams and poles must be as that is what is doing the heavy lifting of the canopy above.
Rolled formed- Sheet Metal building products that are 36 inches wide - Numerous different types of different profiles or styles of numerous different styles of multi-ridded rolled panels(different from a flat pans that are 12 inched wide) are used as a cladding materials for canopy structure. Most all of the flat panels are the very same panels used to build metal buildings that are formed from a coated sheet steel that are available in different thicknesses and numerous and different color options. Different product provider offer various different product profile and thicknesses. NOT ALL PANELS ARE THE VARY SAME or just a like.
Craftsmanship without Compromise!
Structural Insulated Panels (SIP) -Foam core Insulated Panels are pressure laminated composites of baked, polyester-coated steel or aluminum coil sheets that have been roll formed, and computer cut and routed expanded polystyrene foam (EPS). These elements are laminated under pressure with an adhesive to produce a panel having structural and insulated properties. SIPs are great for any type of outdoor canopy structure and have been used within the sunroom and cold storage industry for several years but is now becoming more main stream framing panels of today.
SIPs are the newest and most advanced form of framing methods as apposed to the traditional stick or metal framing methods.
SIP panels are available in 2 -12 inch panels thicknesses with different - steel, aluminum or a OSB wood cladding and different colors and cladding type options. The canopy top covering as a whole wall or a roof structural panel in itself are unlike the traditional stick framing disciplines the SIPs is a whole structural panel in itself. Think of it as if we just framed a wall with 2x4 studs then added a super insulation, then cladded the exterior and the interior walls all in one building panel. Sips stay warmer in the winter & cooler in the summer.
Insulated patio cover roof panels are great for energy efficiency, and are extremely rugged in design, supporting up to 72 lbs.per sq foot. The insulated foam panels are 15 time more airtight then stick framing and reduce the heat transfer coming though the panel by 97 percent and can dramatically reduce the temperature underneath the canopy cover. SIPs are vary strong they do not require as much understructure framing like traditional stick framing methods would require.
The exterior cladding of the SIPs are available in a 26ga steel or a various thicknesses or a .030 cladding options. Today we also blur the lines by using a 4 inch SIP panel that is cladded with a OSB plywood so we can nail the shingles onto the exterior SIP panel surface.
The SIPs offers advantages over any single ply rolled formed carport canopies when used within a hail prone areas. If there are hail dinged on top of the SIPs you won't see the dings from the button side of the panels. The SIPs canopies are much quieter and you don't hear that pinging noise that you might hear during a heavy rain or hail storm event. They are superior in the thermal blocking and reflecting any heat transfer though the Sips in the heat of the summer.
Metal -(steel and aluminum) always has an advantage to any wood product when used within an outdoor environment because of its life span and its strength. The metal materials are stronger which allows us to span much longer and wider open spans between poles. Heavy gauged metal allows for much shallow roof pitch designs as apposed to wood products and you don't have to use near as much building materials such as using setting metal trusses on a 4 ft OC wide setting versa the wood product might require us to be at a 12" or 16" inch OC settings. That facts are we can have a larger open spans between the building materials with metal products over and wood product with a much lower pitch design which we are always limited within a add on type of building application.
We also offer heavy gauged galvanized steel that has been galvanized coating process to keep the steel framing members from rusting. The galvanization process is additional costing process that the steel framing members has been put though and seal the steel member from rusting. The galvanized products looks much like a chain link fence and it has a bright silver color and can be trimmed out and covered. This can make a good looking strong low maintenance carport canopy structure and is preferred over just using exposed red iron or red steel framing members.
Unfortunate before the steel is purchased most of the steel members has been left outside in a steel mill yard before being transported to a local steel providers sales yard and sometime the building member are already starting to surface rust when they are picked up from the steel providers location. So they might use a penetrating oil on the steel members to wipe the surface rust off until the products are sold. So all red iron need to be protected or it could become a huge "rust bucket" within a short period of time.
Today we have deal with numerous different local specific building code regulation and requirements and/or engineering criteria's that are updated all the time without notice by the local municipalities and are ever changing and much stronger then before.
The larger municipalities the more likely they will have some type of building permits with regulations to what type of carport canopy structure that may or may not be build.
Most of cities or towns do not allow those blow away carports using trailer home anchors to secure the structure as they can dangerous for the neighborhood and first responders as a whole in a high wind weather storm event. It is the customers ultimate responsibility to find out and to know what there local building codes may or may not allow.

A 24 x 20 ft stand a long butted up to the house but not attached all aluminum flat pan carport canopy structure using 3 - 7 inch .125 or 1/.8 thick beams and 6 - 4 inch .125 aluminum poles clay or cray in color and the understructure beams are bronzed in color.3 of the 6 poles are cored drilled into the driveway and the others are into a cement pears into the ground.
FYI before you buy: Within the steel industry the lower the gauge of thickness the heavier the panels or pans are. Within the aluminum industry the higher the gauge of thickness are and the heavier the panel or pans are.
A 24 x 24 attached oversized 2-1/2 car 8" inch pained steel full boxed framed carport structure to accommodate a larger truck and car as well as a side walk to the front of the house and there porch area. These customers has had a carport in there past that made noise every time the wind blows and in OK that is most of the time. They wanted something that was better build. Built on the S.W side of OKC.
A rustic cedar wood 20 x 24 ft attached cable style roof design carport structure with a completed and finished out underside inside roof. The wood is fished and sealed to keep the structure looking great. Built in N.W. OKC near NW 50 th & Portland Ave
Actual building designed may need to be reviewed by a licensed engineer, City or Town code enforcement official for local code requirements. Each and every municipality has there own set of rules and regulations known as codes requirements and of them all are subject to change without notice.
We are only interested into building a quality carport structure or the long term and adding to your property value versa a temporary and under built and dangerous solution. Those portable type of carports where designed as only a temporary structure mainly to cover some hay out in field from getting wet and not used to cover any expensive vehicle.
A 24 x 20 ft attached rolled formed 12" wide x 3 inch high aluminum flat pan with 10 inch aluminum C beams and 3" inch lock seam steel poles. All white in color. Built near Shawnee, OK
A 300 X 40 ft huge 60 car C Beam and Purlin carport canopy structure with a steel 26 ga metal covering. Frame has been welded together and painted. Poles are a 10 ga steel and all of them are into cement pears.
I spent two hours under this carport canopy structure during the wicked El Reno tornado event that came across the OKC area with some very strong winds and a lot of large hail. It is a 60 car trued and tested carport canopy built to last in N.W. OKC
Extruded aluminum framing components -It is a fact that aluminum is not a strong as steel at its vary same thicknesses. but we can always use heavier, thicker and as strong as steel "extruded aluminum" beams and poles to build a carport canopy frame with that is equal or better then any steel product. Plus have a much liter structure weight known as live load to began with then using the any steel products. all wind and snow loads has to be considered when building any type of structure. The big advantage is that the aluminum building products will never ever rust. No matter if they finished painted or not. So the aluminum is the preferred building product materials used within most types of outdoor applications such as out door furniture and so on and so fourth. Most all aluminum building materials are available as a painted and finished product today so like with any finished building product but they just cost a little more then a unfinished building materials. A fully finished aluminum carports canopy structure will look good today without any future maintenance issues and the same in twenty years. A .125 or 1/8 inch thick extruded aluminum framing components is equal to 20 ga thickness of steel product.
On the other hand a structural engineers is trained to understand. predict and calculate the stability, strength and rigidity of a built structures for a building structure, to develop designs and integrate their designs.
A engineered carport system is constructed from a engineer that is licensed within the build state. That structure are designed to meet all local and state building codes requirements.
Each and every carport project stands on it own and is unique onto itself and there are no two types canopies that are just a like!
Rolled formed pans -Flat Pans or W- Pans are a machined rolled formed type of building material used to cover canopy structures. The big difference between the two pan systems is what you see when you look up while under the structure. With the W pan you see a corrugated type or a V or a W types of shape ceiling. With the Flat pan your see a flat ceiling. That looks like one big panels when constructed. Plus with the W pans has to use a foambird blocks to keep the birds from nesting in the under the canopy top. These pans types are formed into their final pan shapes out of metal (steel or aluminum) rolled coil flat stock material available in various different thicknesses and color options that is ran though a bending machine that has a series of roller and forms the pans to it final shapes and cut to its final length.
These pans and are joined and interlocked together to make a solid type of clean and modern canopy structure. Roll formed valance and gutters adds an attractive finishing detail for aesthetic appeal. A built-in roll formed gutter system assures quick rainwater run-off to protect the integrity of any structure. These 8" or 12" inch wide x 3 inch high pan shapes are available in various different pan colors as well as various different canopy gutter trim colors that you may choose from that are joined together. You can also combine any color of pan to any color of guttering and make a two tone color canopy top. Note: Their are difference thickness of coiled flat stock available and each canopy pans can be ran in a steel product or a aluminum product.
Aluminum pans can be made entirely out of aluminum flat stock, including its under support frame systems, that is superior to and wood, iron, steel, and metal covers because they will not rust now or in the future.
There are economical grades of aluminum rolled form pans (.019 or a thicker .025 rolled pans) or a upgraded .032 that refers to the thickness of the aluminum or 26 gauged steel pans which are equal in there strenghts. The pans can be boxed on one end to help prevent water from blowing into the wall header frame or we can use a optional full perimeter guttering system. Stamped aluminum leaf guard snaps into end of pan at gutter, helps to prevent leaves from building up in its built in guttering system and gutter scopes or down spout's can be used.
A foam insulator insert panel can be used which allows for single ply carport canopy material to be retrofitted with a foam core insulation and top covering panel that can be added during the installation process. The Insulator adds energy efficiency while adding protecting the lower pans and also does not allow the heat transfer though the pans. Much like the SIP panel carport panels below.
We do not market nor sell any type of those fake and flimsy so called "portable" or tempory carport cover structure because most of the time we can offer a custom carport structure that is far more superior. We call them "blow-a-way carports" because that is what happens when the winds come swiping down the southern planes as those light weight things turn into flying UFOs they can do a lot of damage to your and neighbors property while blowing down the street.
Carport Trim - Add carport canopy trim options - There are various different trim options that are available for different types of types of canopies.
Metal / Steel Bent Trim -Various and different type of steel coil in bent into form to shape various canopy and pole trim is used to trim out any type of metal carport structure. There are different trim pieces used to hip, valley, and ridges and side and front trim pieces. water guttering, scoops and down spout's also can be added.
Structure Framing Materials -Much like our skeleton in our body the canopy under structure or
frame of a carport is what holds any structure together and does all of the heavy lifting. Types -Wood - Wood truss, Engineered Wood and Wood composites. Metal - Red Iron or Structural Steel, Galvanized Steel, Aluminum, Fiberglass are all used to build any one type of canopy structure.
Wood -Wood framing run deep within our roots and we are ole framers from way back. All building products should be used for the purpose of which are intended and all has their own building limitations. All wood product has to be protected so they won't be effected by moisture and decay faster as well as being protected from bugs such as termites. When using wood within a outdoor environment you have to be commented to protecting and preserving the wood building products from the weather or the wood is going to turn a dull gray color and not look very good within a just a few (3) seasons. We call it wood weather rot. When wood is used within a outdoor application it is always suggested that we use a premium wood that performs better within a outdoor application such as a Cedar or a Redwood. Those types of woods is considered to be a premium wood products and just cost more the standard white pine stick framing members that the framing members are normally going to be covered up with wall or roofing cladding materials.
Using the premium woods does have a higher overall building cost. Their are always additional services such as roofing and painting services that has to considered when using of any wood products. Wood has a "limited life span especially when used within a outdoor use application. The facts are we always use a whole lot more sticks and timber while framing the same type of open span outdoor structure as we do using as metal product. As much a 4x times more wood products are needed to safely cover the same open span as a metal product. Normally there has to be at least 3-4 time more roof pitch when using wood product over metal. Within In a add on type of structure applications that ties into the existing structure we must be sure that that the existing structure is designed or engineered to handle any additional structure and that may required to add to the structure. Additional professional architectural services may be needed. With that being said their is nothing that look like and the smell like a nice cedar wood framed structure and some just prefer the rustic look of a nice wood framed structure.

Design / Build / Contractor
Do you have a insurance company or a local city or town code requirement that requires only a engineered type of carport structure to be built ?
There are engineered and designed carport canopy structures then there are non-engineered carport structures that may not meet any local code requirements.What are your building requirements?
Don't waist your time or money with those cheap built and flimsy blow-a-way portable temporary carports. I don't care what they might claim or what there sale pitches might be...
A 20 x 20ft attached 14ga 6" inch galvanized steel C beam full boxed frame carport with 3"x3" lock seam painted poles and withs26 gauge steel canopy top and finished side and front trim built in MWC, OK
There are two different basic sections of any type of carport canopy structure.
1 - The understructure or the frame and the beams and poles of the structure that does the heavy lifting.
Very different types of structures require different frame requirements depending on its size, open spams and design and building requirements.
2 - The "canopy top" or its covering.
There are different types - Rolled formed metal flat panels - flat pans - W pans - Structural Insulated Panels (SIPs) that are available in steel or aluminum offering in different thicknesses and color options. We also offer a thicker commercial grade extruded aluminum end steel covered carport canopy structures as well.
Hey carport man!
Fiberglassframing components - is the new kid on the block andoffers the ultimate in canopy component structural pultrusion FRP building products have a superior long-term resistance to chemical corrosion, salt water or rusting or the term weathering. Like the extruded aluminum building materials are pulled though a die to form its final shapes which is called a pultruding process. These final pultruded products will not rust, rot, scale or mildew and can be finished and painted. The fiberglass building products offer the strongest building products with lowest live loads and is not normally effected by hail damage that the metal products can be. The availability of the fiberglass building products are limited and they are considered to be special application product mainly because of the cost of these products at this day in time.
Carports of Oklahoma offers real carport solutions for year round protection from snow and ice during winter season, from rain and hail damage during spring season. from the harmful sun's rays and the sizzling hot heat during summer season, from the all the stuff that can fall from the trees in the fall season that can damage your vehicles finish!Get year round protection!
When we say that we custom build carport structures the key word is custombecause we offer a very diverse product offerings and we can fabricate these structure out of numerous different buildings supplies. We custom build because their just isn't one type, one style, one design or cookie cutter type of carport design to fit all applications.
Pre-engineered carport canopy designed system has been designed by a manufacture provider that has been designed and engineered by a independent design consultant firm or a qualified architect as per the span, wind or its dead and live load carrying capacity. Building specifications has been calculated and signed off on by a State approved professional design engineer. That professional has to sign with his own stamped and seal of approval. That is a signed engineering document that says that the engineered structure has been approved and will meet a certain dead and live loads requirements such as wind, snow, earth quake load requirements. This type of engineered canopy may be required by a insurance companies or local authorities having jurisdiction or local building permit office. These product documents says that he structure meets its design standards. The product provider can show a signed engineering design documents that some of the local cities now are requiring. If a project requires blueprintswith productengineering stamps then there are there are additional charges for those additional professional services to be provided.
Engineered or Non-Engineered carport canopy systems ? - A non engineered carport is normally built using various different building materials and by a builder just various different type of building material from a local provider. That builder is building a structure and that does not meet any specific building code or engineering criteria. This a non engineered structure!
Steel -is stronger then aluminum building materials at the vary same thicknesses, that is a fact. Steel is used in skyscrapers and outdoor environments such a bridges but always require surface prep and painting and on going maintenance such as painting or coating services. Structured steel is available in numerous different building products shapes and sizes that are available in different thicknesses or gauges and are normally sold in 10, 20, 25 or 30 ft lengths with or without different protective coatings. The raw steel is black in color but is normally sold with a quick surface shop primer red coating or a upgraded primer coatings. An additional coating process would be a galvanized, painting or powder coating services to protect the steel metal.
The entry level red iron steelframing components are used in a lot of covered metal building that are protected from the weather. Steel is strong but it is a furious material and has iron within it so any type of moister even humidity in contact with the steel can cause the steel member to start to rust. Carports are a outdoor building structure that are exposed to the weather and its moister. Over 65% percent humidity is like spraying water on the exposed steel. So the steel providers coat the (black in color) steel members with a red oxide shop coat finish that is just a primer coating protect the steel framing members from rusting until there are sold to the end user. It is suggested that all primer coated materials be prepared for paint ASAP especially in a outdoor use. The furious metal is going to rust in time and the better the primer, intermediate and finish coatings the metal building components have applied to them the longer they will keep from rusting. Do your research on metal surface preparation.
There is huge difference between a 12 ga 2"x 2" bent fence post tubing canopy viruses a 6" or 8" high 12 ga C or I beams with fully boxed frame strong carport canopy structure system. There is no comparisons to how these structure will hold up while under any type of stress such as wind or snow and ice loads.
Wood - Because carports are a outdoor structure we normally use a cedar or a premium type of wood or a engineered wood product such as a composite type of wood product. Most wood canopy structures are required to have a much sharper pitched roof design and are built similar to a traditional stick frame or a timber frame design roofs. The interior roofs or the underside of the roof canopy may or may not be finished and the roofing timbers may or may not be exposed. All exposed timbers should be finished to protect them and for longer life spans. Most of the time the exterior roof are finished out using either a metal or shingled type of roofing materials. Today anything is possible and we mix and match newer building materials all the time.
To prevent unfinished steel from rusting. We can offer painting and/or powder coating services for new building materials before they are installed for additional service charges. In some cases the customers are willing to there own painting and we can work with that.
Adding onto a existing roof structure - A carport canopy structure can be built into or onto most existing roof structure. But the existing roof structure may not have been built or designed to handle any additional added load of a new add on structure. It is always best to have a more detailed and professional plan when adding onto any existing roof structure. An architectural engineered should be consulted to make sure that the existing structure is able to handle the additional loads of any added structure. Most of the time there are extra internal frame bracing that might be required to add any additional weight to any existing framing structure. It is always best to remove some of the roof decking and cladding to be able to tie directly into the frame of an existing structure as opposed to cutting corners and taking risks.
In Oklahoma is where the server weather is like no other place on earth. We live in the middle of tornado and hail core ally of the US. If you do not have a garage structure to park your vehicles within then a carport canopy structure is a necessity to protect your vehicle(s) or RV investment(s).
A carport canopy structure are cheaper to build then a garage but they should not be so cheap that they might be under constructed and they are not fit for use and is a danger to you or the community. We fight that today because there is a lot of cheap junk that is marketed and sold all over the internet and by road side vendors every where. You don't have to settle for less!
