A homemade steel carport can be a cost effective alternative to a garage or prefabricated kit. With basic tools and supplies available from any hardware store, a steel carport can be built over a short period of time to provide shelter from the elements. To build a homemade steel carport, you will need a basic understanding of metalworking.

Skill level:

Things you need

  • 8 foot steel posts
  • Metal ground fixings
  • Corrugated metal sheeting
  • Welding equipment
  • Hacksaw

  1. 1

    Measure the area of your carport and mark each of the four corners. This is where each of the posts will be fixed.

  2. 2

    Cut two of your metal posts down to 7 foot with a hacksaw. This will provide a slant on the roof of your carport to prevent rain or snow from gathering on top of the carport.

  3. 3

    Insert one of the four metal posts into the ground fixings and position in each corner, ensuring the two 7 foot posts are adjacent.

  4. 4

    Attach the ground fixings to the ground, using bolts and a masonry drill where applicable to secure the carport to the ground. The carport can also be anchored by bolting to your home, or another garden structure.

  5. 5

    Weld the corrugated sheeting across the top of the carport frame to create a sloping roof. Weld to each post to firmly secure the sheeting to the frame.

Tips and warnings

  • For a more severe angled roof, trim an extra 6-inches of each of the 7 foot poles. This will increase the gradient of the slope in your roof.
  • Make sure your carport is firmly anchored into the ground or your home. Carports are prone to vulnerability in extreme weather, so anchoring provide stability and integrity to your carport.
