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.

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.

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.

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.

Available on 4024, 4022 and 4032 models.

GSI’s 4032 36’ (10.97 m) and larger feature the precision-engineered Z-Tek™ Roof System. Designed for increased load capacity, the system incorporates z-shaped rafters and purlins, clips, peak ring, flat top, and roof panel for unsurpassed strength and protection.
