DIY Steel Carport

Measure and level the ground where you will build your carport. Dig holes to the depth required by the manufacturer's instructions, using the posthole digger. Most holes will need to be at least 24 inches deep in most municipalities. Prepare enough concrete mix to fill one hole. Pour the concrete into the hole and set the first post.

Align the post using the post level and secure it in that position so that it does not move while the concrete cures. Continue mixing concrete and pouring the footers as you assemble the carport. Check your work periodically to be sure it is level. As you progress with the project, install the bottom rails, top rails and trusses as you go along to help keep the structure stable. Tighten the fasteners with the screw gun.

Install the roof of the carport. Have two people on ladders, each one working on one side of the carport. Tighten the fasteners on the roof pieces with a screw gun. Use the tin snips to trim the roof pieces as necessary. Install all support brackets in the kit as well and tighten the bolts with a socket and ratchet.

For carports that have panels, install those after the roof is complete. Use a screw gun to tighten the fasteners. Use the tin snips to trim the side panels where the terrain is not level. Check your work as you go along with the level to be sure it is square.
