Roof Panels

Callout Image
The new 40-Series roof panels incorporate a 3” tall rib with over and under lap profiles ensuring a precise fit. 3 bend rib profiles are also incorporated in the new design for increased strength to stand up even in the harshest of environments.

Superior Protection

Callout Image
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.


Callout Image
GSI’s stiffener profiles and the use of up to 2-gauge material make bins stronger, allowing 40-Series Bins to go taller without the extensive use of lamination. 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.

Dura-Lok Flooring

Our most popular floor option, Dura-Lok flooring is the strongest floor available, making it ideal for tall bins. Supported by a post and beam system, the Dura-Lok floor features 3.5” wide sections for a stronger, easier-to-clean, and more stable floor.
