How to Build a Metal Carport at Home How to Build a Metal Carport at Home
Assembling a metal carport yourself is a relatively easy process. More often than not, they never need more than two people to put up, and sometimes they can even be done by just you. Usually a pergola carport kit will have its own instructions on building a carport, but not always. That is where this tutorial comes in. Below are instructions on the general set up of a carport kit.
Step 1 – The Foundation
While not as permanent a structure as your house or garage, a stable carport still requires a solid foundation. A concrete slab works best for this. If you already have a concrete space you are willing to use, measure it to be sure it meets the size specifications for your carport. If you don’t have one, making one is fairly easy.
Use some 2x4’s held together with L brackets to build yourself a low retaining wall. Be sure that the wall is big enough to meet your needs, and check the level all the way around. Pour your concrete mixture, and allow ample time to dry.
Step 2 – Owner’s Manual
Before going any farther, you should always read the owner’s manual if you haven’t already. This should give you detailed instructions on how to assemble your carport kit (which may differ from these instructions) as well as advise you on various precautionary measures as well as tools and materials that will be needed for the job.
Step 3 – The Rails
Start by laying out your bottom rails, which are the horizontal pieces of your carport frame. If possible, bolt your rails into the concrete, but be sure that bolting them won’t damage them in any way, or interfere with the rest of your assembly. You may need to purchase or rent specialized tools for cutting into the concrete.
Step 4 – Uprights and Girts
Your uprights are the vertical posts, which will be supporting your roof structure later. You’ll have at least 4 of these, one for each corner, though if you have a double carport or similarly large design you may have more. Attach these around your bottom railing, and then attach the top railing to your uprights. Depending on the design, you may also prefer to attach the top rails to your uprights first, then position the whole frame into place over the bottom rails.
Girts are support pieces throughout the sides of your framework, which may or may not be present for your particular model. They may also simply be called side supports or some other general title. Attach these after attaching the uprights and rails.
Step 5 – Trusses and Purlins
Trusses are the main frame pieces of your roofing, which you’ll attach once the rest of the siding is stable and in place. Purlins are further support pieces for the roof that may or may not be present, but should be attached last after the trusses.
Step 6 – Roof and Sides
Now that you have your framework down, go ahead and attach the room. Once it is securely in place, attach any siding that you may want as well.
While this will get you through most installations, these are generic steps only and should be treated as such. If your owner’s manual tells you something different, be sure to follow its instructions.
