Quad Bolt Punching
"Quad" Punched Bolt Pattern
GSI utilizes a "quad" punching pattern in most of the vertical bolt seams of the sidewall to assure a strong connection between panels.

A world leader in steel corrugated storage grain bin manufacturing, Grain Systems offers the strongest and heaviest gauge storage tanks in the industry with capacities exceeding 710,000 bushel (20,000 MT). Our tank sidewall is roll-formed at the GSI plant using 8 gauge, and now 5 and 6 gauge, prime high tensile steel up to 65,000 PSI (450 MPa). The heavier 5 gauge sidewall allows us to provide taller tanks with our advanced design, compared to other manufacturers who provide 8 gauge as their maximum thickness.

8 Ga. ASTM A-653, SQ Grade 50:

50,000 psi Minimum Yield Strength

65,000 psi Minimum Tensile Strength

5 Ga. High Strength - Low Alloy Steel:

55,000 psi Minimum Yield Strength

70,000 psi Minimum Tensile Strength

8 Gauge Vs. 5 Gauge Galvanized Steel
The heaviest galvanized steel previously available for sidewall panels was 8 gauge (.164"). GSI's exclusive 5 gauge (.205") galvanized steel sidewall panels however are 25% thicker and provide up to a 37.5% increase in overall strengh. In addition, GSI uses a commercial galvanized coating for lasting durability and heavy zinc plated, high strength, High Strength Bolts dichromate coated bolts (up to grade No.8) on all bins. Each bolt has a special sealing washer for an unbeatable weather seal.

65,000 PSI High-Strength Stiffeners
Strong upright stiffener columns carry the vertical load of the grain silo to the foundation. Manufactured from high strength 65,000 PSI (450 MPa) steel, GSI's stiffeners feature strong splice joints with large cross sectional areas, both critical elements of vertical stiffeners. Stiffeners are galvanized and mounted either internally, or externally, based on your requirements.
