Increased Strength
Roof Panels
40-Series™ roof panels incorporate a 3” (76.2 mm) tall rib with over and under lap profiles ensuring a precise fit. 3-bend rib profiles are also incorporated in the design for increased strength to stand up even in the harshest of environments.

Stairs, Ladders, Cages, Platforms
Accessibility
Your safety is a top priority. Durable and weather-resistant GSI stairways, ladders, cages, platforms, sidewall doors, steps, and roof caps are designed to provide safe, convenient access points.

Superior Protection
Sidewall Sheets
Each GSI bin is efficiently designed to handle maximum loads for unmatched strength. Most sidewall sheets are manufactured from high-tensile steel that is rated at 70,000 psi (480MPa) or greater.

Improved Stiffener Profile
Stiffeners
GSI’s stiffener profiles and the use of up to 2-gauge material make bins stronger, allowing 40-Series Bins to go taller. Improved stiffener profile design is manufactured on precision roll-forming equipment for superior quality. Base stiffener boots are powder-coated so they won’t rust over time.
