The Gold Mountain W20'xL30'xH12' Single Truss Arch Storage Shelter provides approximately 600 square feet of protected space for equipment, vehicles, materials, tools, and machinery. Its 12-foot height gives you useful overhead room while keeping the shelter compact enough for smaller storage areas.
The single-truss frame uses 16-gauge galvanized steel tubing with high-grade hot-dip galvanizing. The corrosion-resistant frame is built for outdoor storage and has a stated 15+ year lifespan.
The heat-sealed PE fabric is water-resistant, UV-resistant, and translucent. It helps protect stored items from outdoor exposure while allowing natural light to enter the shelter.
The shelter has a stated 18 lb/ft² snow load and 40 mph wind load. Its temperature resistance is rated from -22°F to 158°F for use across a wide range of outdoor conditions.
The front and rear zipper roll-up doors measure 14 feet wide by 10.5 feet high. The large openings make it easier to move vehicles, equipment, tools, and materials in and out of the shelter.
Predrilled footplates simplify assembly, while the shelter can be relocated when your storage needs change. The manufacturer specifies assembly with two people.
The pipe and ratchet tie-down system makes it easier to tension the fabric cover. Proper cover tension helps maintain a secure fit and reduces sagging.
