Inside Combo or Garage

These are standard sizes for Vaulted Carports, Garages, and Combos; however, we can build them any width needed up to 45' wide. The length of our standard carport is 21' and standard combo is 31'. We can easily add to that length in 5' increments to make your carport or building 26', 31', 36', or 41' long and so forth. The standard height on the 12' and 20' wide Vaulted Carports and Combos is approx. 7' at the side bend and 10' at the peak. The wider carports, combos, and garages are slightly taller. We can build your carport or building taller than standard height to suit your needs - up to 12' high at the side bend which will accommodate even the newest RV's and Motorhomes.

All Vaulted Carports and Combos are available with gabled ends, extra side panels, full back walls, or as fully enclosed buildings.


Garage Framework

A-1 Construction's metal buildings are constructed of 14ga 2 x 3 galvanized tubing which is also clear-coated inside and out (highly rust resistant). Size for size rectangular tubing requires nearly 3 times the force to bend as round material. This means completely galvanized rectangular tubing will support thousands of pounds more than the same size structure built from round tubing. We use 29ga max rib Galvalume and Galvanized Steel roofing and siding material with a baked-on Siliconized Polyester paint which carries a 25 year limited manufacturer's warranty.

Our Vaulted Carports, Garages, and Combos are engineered to withstand up to 110 mph wind and a 30 pound liveload or snow load.

Construction information:

We can build your Vaulted Carport or metal building on the ground, your concrete slab, asphalt, or gravel driveway. The ground does not have to be level. Most carports and RV covers can be built in less than 1 day. Larger buildings and combos can usually be constructed in 1 to 2 days.

We stock the trim in the following colors - White, Tan, Light Stone, Light Grey, Charcoal Grey, Hunter Green, Rustic Red, Blue, and Dark Brown. All other colors and none standard lengths can be special ordered, usually within one week.
