Specifications of 18 x 21 Vertical Roof One Car Garage

As with all of our other vertical metal garage buildings kits for sale, this garage comes with some standard features. The building draws its strength from the 14-gauge tubular framing.

Not only that! This metal garage also comes with some structural components that are particular to this type of prefab metal garages, like the hat channels, ridge caps, etc. which add to the overall strength of the building. Because of this strength, our vertical metal garages can withstand any weather loads.

A 12-gauge tubular upgrade is also an option we offer to people looking to enhance the robustness further. By, default, the wall panels are horizontally oriented. But you can choose the option to completely enclose the metal garage with vertical panels for that added strength.

A metal garage door of dimension 9' x 8' at the front end is perfect for the movement of cars, trucks. It can also accommodate smaller private boats or camper vans. The walk-in door at the side, meanwhile, is fit for regular access. It saves you the trouble of opening and closing the garage door every time you want to enter the garage building.

Benefits of 18 x 21 Prefab Metal Garage
