Create serious storage space for equipment, materials, vehicles, agricultural supplies, and commercial operations with the Gold Mountain 40' x 80' x 20' Single Truss Arch Storage Shelter.
With an expansive 3,200-square-foot footprint, this heavy-duty fabric shelter provides a versatile alternative when conventional sheds simply aren't large enough.
Its combination of a 14-gauge galvanized steel truss frame, heavy-duty outdoor fabric, ventilation, pedestrian access, and stake-peg anchoring makes it suitable for agricultural, warehousing, manufacturing, and other large-scale storage applications.
The Gold Mountain shelter measures approximately:
40' Wide x 80' Long x 20' High
That provides approximately 3,200 square feet of covered floor space.
The generous dimensions make it possible to protect larger quantities of equipment and materials under one structure while maintaining the flexibility of a fabric storage building.
The large open interior can support a variety of storage applications.
Use it for farm equipment and agricultural materials, machinery, vehicles, raw materials, tools, manufacturing supplies, or other items requiring substantial covered space.
The manufacturer also identifies potential applications including storage of grain, sand, coal, and livestock.
Customers should confirm that the shelter configuration, ventilation, anchoring, flooring, and other site conditions are appropriate for their specific intended use.
The shelter is built around a 14-gauge galvanized steel single-truss frame.
Galvanized construction provides a robust structural foundation while helping protect the steel against corrosion associated with outdoor environments.
The single-truss arch configuration also gives the building its distinctive high-clearance profile while maximizing usable covered space.
The shelter uses a premium outdoor fabric designed to provide protection for stored equipment and materials.
The manufacturer describes the cover as water-resistant, tear-resistant, and UV-resistant, making it suitable for outdoor storage applications when properly installed and maintained.
Maintaining appropriate fabric tension is especially important for long-term performance.
Two vents positioned near the upper ends of the shelter help improve airflow through the structure.
Ventilation can be especially useful in large fabric storage buildings where trapped humidity and condensation may otherwise become concerns.
The actual ventilation requirements for livestock, agricultural products, chemicals, equipment, or other specialized uses should be evaluated separately based on the intended application.
A 2.6' x 6.6' side door provides pedestrian access to the shelter.
This allows you to enter the building for routine inspections or access smaller stored items without relying solely on a larger equipment opening.
This model is supplied with stake pegs for anchoring.
The stake-based configuration can provide greater installation flexibility for suitable sites, but proper anchoring remains essential to the performance and stability of any large fabric shelter.
Ground conditions and local requirements vary. Confirm that the supplied anchoring method is appropriate for your specific installation location before assembly.
The manufacturer recommends assembling the structure with four people.
Suggested installation tools include:
Measuring tape, alignment string, step ladder, power drill, sledgehammer, pliers, wrench, scissors, and other appropriate installation equipment.
Proper site preparation and careful alignment are important when assembling a structure of this size.
Fabric tension should be inspected regularly.
The manufacturer recommends re-tightening the roof fabric at least three times per year to help prevent sagging and maintain proper tension.
Leaves, snow, and other accumulated material should also be removed from the roof. Excessive accumulation can add significant weight to the structure and may result in damage or collapse.
Never assume that the arched roof eliminates the need for snow removal and routine inspection.
Permit, zoning, anchoring, and installation requirements can vary by municipality and intended use.
Before purchasing or installing the shelter, contact your applicable local authority to determine whether permits or other approvals are required for your property and application.
