20' x 40' Metal Garage Shed, 9' High Double Front Doors, 13' Peak, 800 Sq-Ft TMG-MS2040

The TMG-MS2040 Metal Garage Shed with Double Front Doors is a heavy-duty, spacious, robust steel structure that can be used as an outdoor storage facility. Fully enclosed for year-round protection of your boat, RV, pickup, off-road vehicles, and farm equipment.

Two large double front swinging doors with over 9' high access opening give you ample space to drive into or bring materials in and out of. The included side door entry can be installed on either side, allowing you to customize this enclosure to fit the needs of your acreage, farm, or commercial property. Three large windows generously maximize natural light and create a more pleasant, open ambiance.

Our metal garage features reinforced roof supports, wall bracings, and anchors, making it a dependable structure for the housing of all your valuable goods. It is fitted with electro-galvanized steel sheets and polyester paint that offer protective resistance against corrosion, rust, and wear.

The sloped gable roof helps shed snow and rain, while the slip-fit base frame with sleeve anchor bolts allows for quick installation on wood or concrete foundations. The open-span design inside provides maximum interior space and flexible storage options.

Note: Performance depends on installation quality, ground conditions, and weather. We recommend securely anchoring the structure and removing snow buildup in heavy winter conditions to ensure long-term durability.

TMG also carries similar models with different sizes: TMG-MS2020, TMG-MS2030.
