30x45x10 Metal Garage

Looking for a spacious metal garage with room for multiple vehicles, equipment, or a dedicated workshop? This 30x45x10 Metal Garage provides 1,350 square feet of enclosed space, giving you plenty of room to protect vehicles, tools, recreational equipment, and other valuable belongings.

Built with a durable 14-gauge galvanized steel frame and a vertical roof, this metal garage is designed for long-term durability and easier maintenance. The vertical roof panels help direct rain and snow away from the building while providing a clean, finished appearance.

The building features three 8'x8' garage doors, making it convenient to park multiple vehicles or move equipment in and out of different areas of the garage. A walk-in door provides convenient everyday access, while multiple windows bring natural light into the interior and make the space more comfortable for workshop or hobby use.

The spacious 30-foot width and 45-foot length allow you to create a flexible interior layout. Use it as a multi-vehicle garage, automotive workshop, equipment storage building, hobby shop, contractor garage, or a combination of parking and workspace.

Pictured in White with Quaker Gray vertical roofing, this building can also be customized with different colors, doors, windows, trim, accessories, and other options to match your property and intended use.

If you need a large, customizable steel garage without moving into a full commercial building, the 30x45 is a versatile option that gives you substantial enclosed space for vehicles, storage, and work.
