30x40x12 Steel Garage
Protect your high-value vehicles, tools, and equipment with this heavy-duty 30′ x 40′ x 12′ steel garage. Built with a high-strength, rust-resistant steel frame and fully enclosed, all-weather siding, this 1,200-square-foot clear-span structure is engineered to withstand harsh wind, heavy rain, snow, and UV exposure. The broad 30-foot width provides comfortable parking for up to three vehicles or large machinery, while the generous 40-foot length leaves plenty of room for a rear workshop, heavy tool racks, or lawn equipment. Featuring a 12-foot sidewall height, it easily accommodates high-clearance roll-up doors, lifted trucks, SUVs, and commercial vans, making it a powerful storage solution for residential, farm, or commercial use.

Panels lined up better than I expected from the reviews I read.
Finally got the lawn equipment out of the garage. Instructions could be clearer but it wasn't hard to figure out. Would recommend to anyone considering the 30x40x12 Steel Garage.
Really happy with this. Panels fit together better than expected for a DIY kit.
Assembly took a weekend but everything lined up well.
Really happy with this. Sturdy once assembled and has stayed watertight through storms.
