About Our 18x20 Metal Garage

This affordable 18x20 metal building is made in the USA with American steel. With 360 square feet of space, it can be used as a 1-car garage, shop, storage building, or large shed.

Customize the height, doors, windows, and colors above to see exactly how much this 18x20 metal garage building costs with the options you need. We offer free delivery and installation instead of a kit.

Product Description Specifications

This 18×20 garage is 2 feet wider than a 16×20 garage building, giving you a little extra space for storage for about the same price.

Our 18 by 20 vertical-style metal garages come with 360 square feet of storage space and are built tough using 14-gauge 2 1/2″ by 2 1/2″ tubing for the framing. Customers may choose to upgrade to 2 1/4″ by 2 1/4″ 12-gauge tubing instead, which comes with a 20-year rust-through warranty.

Each 18×20 metal building order will also be anchored in place for free upon delivery for added durability. We use rebar and mobile home anchors to secure it to the ground, rebar to secure it to asphalt, and concrete anchor bolts for cement. In order to do so, however, your 18×20 metal garage’s flooring must be within at least 3″ of level.

Additionally, our 18 x 20 vertical-roof metal garages are constructed using a tight screw pattern that, when combined with our anchoring process, certifies them for winds of up to 140 mph and 35 psf.

Every 18 by 20 metal garage order is highly customizable as well. We use your style, options, and size selections to custom-build your dream garage. A few of the optional features available to you include garage doors, windows, walk-in doors, and extra height for an additional cost.

You’ll also be given the opportunity to select from 16 different colors for your garage’s sides, trim, and roof. These colors are approximate and may vary at times.
