Steel & materials

Built from American-made steel

This isn’t a canvas carport on posts. Every 12x35x14 RV cover is a custom steel structure — framed, roofed, and anchored to stand up to decades of sun, wind, and snow while it shelters a big investment.

  • 12- or 14-gauge steel framing. 14-gauge bows and legs are our standard for strength; 12-gauge is the upgrade for high winds, heavy snow, and the extra height a tall cover needs.
  • 29-gauge vertical roof panels. A vertical roof sheds rain and snow off a wide span — fire-resistant, weatherproof, and built to last against hail, wind, and moisture.
  • Color-coated finishes, 20-year paint warranty. A full palette of roof and trim colors, plus a 20-year limited rust-through warranty on 12- and 14-gauge frames.

Owners of buildings like yours

Purchased Product: 30x80x14 Metal Garage

"I just had a 30x80x14 shop put up in Asheville, NC and couldn’t be happier. With a building this size you worry the details will get lost, but the crew was fantastic — they walked the site with me, kept me posted on the delivery, and had the whole thing up faster than I expected. It’s square, it’s solid, and the price they quoted was the price I paid. I’d send anyone looking for a serious building their way."

Purchased Product: 24x36x12 Garage + Lean-To

"We added a 24x36 garage with a lean-to for the tractor and couldn’t be happier with how it turned out. The number they quoted at the start is exactly what we paid — no surprises. The crew showed up when they said they would, kept the site clean, and had it standing straight and solid by the end of the day."

Dale R.
Tennessee
Purchased Product: 40x60x14 Metal Building

"Needed a real four-bay shop for the equipment and got a firm number the same afternoon — no chasing anybody down for a quote. It went up faster than the pole-barn bid we’d been sitting on for a year, and it came in under it. Doors are smooth, the walls are true, and it’s exactly what we spec’d."
