Store Your Assets Safely
Traditionally, grain would be stored loosely in vertical silos. While this storage method is still widely used today, different grain storage needs may drive you to seek alternative storage structures. Your operation may be located in an area where local building regulations restrict building height, preventing you from using a silo. Flat grain storage provides an effective alternative or complementary system to silos. With flat grain storage options from Calhoun Super Structure, you get reliable storage structures for your grain operations.
Our flat grain storage solutions help you maximize space while protecting your assets. Produced with hot dipped galvanized steel and high-density polyethylene (HDPE) fabric, Calhoun’s engineered and durable fabric structures streamline your daily operations with their ease of access and spacious interiors.
Flat grain storage requires protection, ventilation, and accessibility. Calhoun structures provide the ideal environment to maintain grain quality.
Why Calhoun
Maintains dry, free-flowing sand by protecting stockpiles from rain, snow, and humidity, reducing clumping that can disrupt processing and delivery schedules.
Clear span interiors support continuous loader, conveyor, and truck movement, keeping material flowing without bottlenecks.
Engineered to handle abrasive materials, dust, and constant equipment traffic typical in frac sand operations.
Protects inventory from environmental exposure, preserving product quality and minimizing waste.
The natural light provides workers with comfortable and healthy working conditions, while providing adequate lighting. Our hot-dip galvanized steel frames support life-safety and fire suppression systems.
HDPE fabric maximizes natural daylight significantly reduces reliance on artificial lighting; lowering overall operating costs.
Maneuvering tipping trucks is critical in your industry. Our wide-span interiors have no columns, providing maximum clearance for trucks and other equipment to navigate the facility with ease.
Exceeds winds 150 mph and snow loads 300 lbs psf. Protects critical equipment, materials, and maintenance areas from wind, snow, and extreme temperature swings.
Tell us about your project goals, building requirements, site location, and intended use. Whether you need bulk grain storage, conveyor and material handling system covers, or loadout, transload, and distribution terminals, our team will help identify the right building solution for your operation and budget.
Once we understand your needs, we review key project details including building dimensions, access requirements, fabric options, doors, ventilation, insulation, and site conditions. We also evaluate local wind, snow, and environmental loads to ensure the structure is designed specifically for your location.
After project approval, our engineering team performs a comprehensive site-specific review using advanced 3D Nonlinear Finite Element Analysis (FEA). Once engineering is complete, the steel framework is fabricated, hot-dip galvanized, and prepared for shipment alongside the fabric building system.
Calhoun offers installation services through experienced crews or can support your preferred contractor. Following installation, our team remains available for inspections, maintenance, repairs, fabric recovering, and relocation services to help maximize the lifespan of your investment.
