Building Carports Out of Steel for RV Storage:

When you are building carports you will necessarily need the help of at least 3 other people. Steel carports can be used for recreational vehicle storage and will protect the RV from rain and snow storms. The materials you need to build a steel carport are inexpensive and you can place the carport anywhere in your yard or in the vicinity of the garage doors.

You Will Need: 

  • 14 gauge steel poles (4)
  • Posthole digger
  • Concrete mix
  • Ready made steel carport roof
  • Drill
  • Bolts (1/2 inch)
  • Nuts
  • Lock washers
  • Wrench
  • 4 Ladders


Step 1 – Measure Your Vehicle

RVs come in various sizes and in order to build a carport that is suitable for your vehicle, you need to measure it. RVs may have lengths between 18 and 40 feet and can be around 15 feet wide. The measurements provided here are for a vehicle that is 25 feet long and 15 feet wide. You can use these measurements as reference.

Step 2 – Establish the Corners of Carport

Measure a 14 ½ by 24 ½ feet rectangle on the ground, where you intend to place your carport. Mark the corners, which will be the points where the steel poles will be placed.

Step 3 – Install Steel Poles

The steel poles you use should be sturdy enough to hold the steel carport roof, so choose poles that have at least 3 inches in diameter and should be 8 feet tall.

You need 4 poles, one for each corner. You will have to dig a hole for each steel pole. Each hole should be 24 inches deep, so that the pole will be stable.

Step 4 – Fill Holes with Concrete

You will have to fill the holes for the corner posts with concrete, which will make sure the carport will stay in place. Mix the concrete as recommended on the label of the package. Pour the concrete in the four holes after inserting the poles. Have someone hold the pole while you fill the half of the hole; allow to set in for 10 minutes. Pour the rest of the concrete, until the hole is completely filled. Concrete will take up to 3 days to dry completely, so you will have to wait before you move on to the next step.

Step 5 – Place the Roof on Poles

You can buy a carport roof that is cut to size. In this case, you need a 15 by 25 feet carport, which will have an inside of 14 ½ by 24 ½ feet to fit the corner posts. You need help to place the roof on the poles. Get 3 more people and use ladders to lift the roof; adjust the roof so that it rests on all 4 poles.

Once the roof is placed on the poles use screws to anchor it.

Drill holes in the corners and insert ½ inch bolts, nuts and washers. Tighten these using a wrench.
