Create substantial covered storage space for your farm, business, or commercial property with the Gold Mountain 40' x 80' Double Truss Storage Shelter.
Designed for large-scale equipment and material storage, this shelter features a reinforced hot-dip galvanized steel frame, a peaked roof, front and rear mechanical roll-up doors, and a choice of PE or PVC canopy materials.
With a 40-foot width, 80-foot length, and 21-foot overall height, the shelter provides approximately 3,200 square feet of covered ground area.
This particular model features 10-foot truss spacing, eight structural arches, and a manufacturer-listed 48 PSF snow-load rating and 60 MPH wind rating.
It is a practical option for customers needing a large enclosed shelter for compatible vehicles, equipment, machinery, and supplies.
The spacious 40' x 80' footprint offers flexibility for a wide variety of storage applications.
Potential uses include:
Agricultural tractors and machinery
Construction equipment
Commercial trucks and fleet vehicles
Landscaping and maintenance equipment
Industrial tools and supplies
Agricultural materials
Seasonal equipment and inventory
Commercial storage and staging
Actual equipment compatibility depends on the door openings, usable interior clearances, and intended storage layout.
The shelter is constructed with a double-truss hot-dip galvanized steel frame designed to support the large fabric-covered structure.
The manufacturer specifies:
16-gauge truss tubing
Approximately 60mm x 1.5mm arch members
Approximately 60mm x 1.5mm purlin members
Eight structural arches
10-foot arch spacing
The galvanized finish helps resist corrosion in outdoor environments, while the double-truss configuration provides structural reinforcement.
Proper installation, anchoring, and maintenance are essential for safe performance.
This version of the Gold Mountain 40' x 80' shelter features 10-foot truss spacing.
The structure includes eight arches and 16 anchor plates, distinguishing it from other 40' x 80' models with closer truss spacing.
Customers comparing shelter configurations should review the manufacturer's structural documentation, anchoring requirements, and intended use before selecting a model.
Truss spacing alone does not establish whether one configuration is stronger or more suitable for a particular location.
The manufacturer lists a snow-load rating of 48 pounds per square foot (48 PSF).
The peaked roof is designed to encourage snow to slide off the canopy.
However, snow may still accumulate, especially during certain weather and temperature conditions.
Monitor accumulation and follow the manufacturer's snow-management instructions.
The published rating should be reviewed against local structural requirements, installation conditions, and the manufacturer's rating assumptions.
The shelter also carries a manufacturer-listed 60 MPH wind rating.
Wind performance depends on proper assembly, anchoring, foundation conditions, site exposure, and other factors.
Confirm that the manufacturer's documented rating is appropriate for your installation location before purchasing.
The shelter features mechanical roll-up doors at both ends, providing convenient access for compatible equipment and vehicles.
Each listed door opening measures approximately 13.1 feet wide by 13.1 feet high.
The dual-end configuration supports flexible equipment movement and allows users to access the shelter from either direction.
A dedicated personnel door measures approximately 2.6 feet wide by 6.6 feet high.
This provides everyday access without requiring the larger equipment doors to be opened.
The combination of roll-up equipment doors and a separate personnel entrance is particularly useful for frequently accessed commercial storage.
The shelter features an overall height of approximately 21 feet and sidewalls measuring approximately 9.8 feet.
The peaked roof provides additional vertical clearance toward the center of the structure.
For tall vehicles or machinery, verify the manufacturer's dimensional drawings and usable clearances before ordering.
The Gold Mountain shelter is available with several canopy fabric options.
The manufacturer lists:
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
PVC canopy materials are described by the manufacturer as stronger and more weather-resistant than the standard PE option.
The fabric covering helps protect stored items from direct sunlight and precipitation while allowing some natural daylight into the shelter.
The manufacturer estimates a 7–10 year fabric lifespan, depending on canopy material, environmental exposure, and maintenance.
Confirm the exact canopy material and fabric weight included in your selected configuration.
The shelter uses a pipe and ratchet tie-down system to maintain fabric tension.
Proper tension helps preserve the roof profile and reduce areas where precipitation may collect.
The manufacturer recommends checking and retightening the canopy after installation and periodically as temperatures change.
This 10-foot truss-spacing model includes 16 anchor plates.
The manufacturer notes that expansion bolts have replaced the previously supplied stake pegs.
If stake pegs are required for your installation, contact customer service before ordering.
Foundation and anchoring requirements depend on the installation surface, local conditions, and the manufacturer's instructions.
