Overview
About the 30x40 Steel Garage With Lean-to
The 30x40 Steel Garage with Lean-To is built for maximum functionality—combining enclosed security with open-air convenience. With a 30x40 fully enclosed garage and an attached 12x40 lean-to, this structure gives you the flexibility to store vehicles inside while keeping additional equipment, trailers, or outdoor tools covered and easily accessible.
Engineered with a vertical roof system, this building ensures efficient water runoff, reduced maintenance, and long-term durability. The two 10’x10’ roll-up garage doors allow smooth access for trucks, tractors, and equipment, while the walk-in door provides everyday convenience.
The lean-to extension acts as a covered workspace, RV parking area, or shaded storage zone—perfect for projects that need airflow and accessibility. Built using a 14-gauge galvanized steel frame and 29-gauge vertical panels, this garage delivers strength, weather resistance, and performance in all seasons.
Whether you're managing a farm, running a workshop, or upgrading your property storage, this combo structure gives you more space and more value in one smart design. Call our building experts to order your custom metal garage today at the best prices.
