Expand your storage capacity with the Gold Mountain 40' x 80' Double Truss Storage Shelter, designed for commercial, agricultural, industrial, and large-property applications.
Offering 3,200 square feet of nominal covered space, this shelter combines a hot-dip galvanized steel double-truss frame, mechanical roll-up doors at both ends, and a choice of PE or PVC canopy materials.
With a 21-foot overall height, 9.8-foot sidewalls, and 13.1-foot-wide entrance openings, the structure provides substantial room for compatible machinery, vehicles, supplies, and equipment.
Its manufacturer-listed 48 PSF snow-load and 60 MPH wind ratings make structural performance an important part of its design, subject to proper installation and the manufacturer's rating conditions.
Measuring 40 feet wide by 80 feet long, this Gold Mountain shelter provides approximately 3,200 square feet of ground coverage.
The generous footprint can accommodate a variety of compatible storage applications, including:
Agricultural machinery and tractors
Construction and landscaping equipment
Commercial vehicles and fleet equipment
Farm supplies and bulk materials
Seasonal equipment and inventory
Large-property maintenance equipment
Actual storage capacity depends on the equipment dimensions, access requirements, and interior layout.
The structure features a double-truss framework constructed from hot-dip galvanized steel.
The manufacturer specifies 16-gauge truss tubing, with arch and purlin members listed at 60mm x 1.5mm.
Eleven arches are positioned at approximately 8-foot intervals, forming the structural framework along the shelter's length.
Galvanized steel helps resist corrosion associated with outdoor environments, while the double-truss design provides a substantial supporting structure for the canopy system.
The shelter is listed with the following structural ratings:
Snow Load: 48 lbs./sq. ft. (48 PSF)
Wind Load: 60 MPH
These ratings should be evaluated against local building requirements, environmental conditions, foundation design, anchoring, and the manufacturer's installation instructions.
Snow accumulation must be monitored and managed according to the manufacturer's requirements.
Large equipment needs practical access.
This shelter includes mechanical roll-up doors at the front and rear, each measuring approximately 13.1 feet wide by 13.1 feet high.
The dual-end configuration allows access from either direction and can support more convenient equipment movement through the structure.
A separate 2.6-foot-wide by 6.6-foot-high personnel door provides additional access without requiring the larger roll-up doors to be opened.
With a nominal overall height of 21 feet and 9.8-foot sidewalls, this shelter offers useful vertical space for compatible equipment and storage applications.
Because the roof is arched, interior clearance varies across the width of the structure.
Always verify the usable interior dimensions and door openings against your equipment before ordering.
The Gold Mountain shelter is available with multiple canopy configurations.
Available manufacturer-listed fabric options:
11 oz/m² (300 gsm) PE tarpaulin
16 oz/m² (450 gsm) PVC tarpaulin
23 oz/m² (650 gsm) PVC tarpaulin
26 oz/m² (750 gsm) PVC tarpaulin
32 oz/m² (900 gsm) PVC tarpaulin
The canopy is designed to provide protection from sunlight and precipitation when properly installed and maintained.
The manufacturer lists a fabric service-life estimate of approximately 7–10 years, depending on the selected material and environmental conditions.
Confirm the exact fabric option included with your purchase.
The shelter uses a pipe and ratchet tie-down system to maintain canopy tension.
Proper fabric tension is important for maintaining the roof profile and reducing areas where water or snow may collect.
The manufacturer recommends checking and adjusting canopy tension after installation and periodically thereafter, particularly following seasonal temperature changes.
The structure includes 22 anchor plates.
The supplier states that expansion bolts now replace the previously supplied stake pegs. Customers requiring stake pegs should contact customer service to arrange the appropriate option.
Foundation and anchoring requirements depend on the installation surface, site conditions, and applicable structural requirements.
Before ordering, confirm that the supplied anchoring configuration is suitable for your planned foundation.
