40-Series™ roof panels incorporate a 3’’ tall rib with over-and-under lap profiles ensuring a precise fit (see illustration). 3‑bend rib profiles are also incorporated in the new design for increased strength to stand up even in the harshest environments.
HIGHER CAPACITY AND SUPERIOR PROTECTION
Each GSI bin is efficiently designed to handle maximum loads for unmatched strength. All GSI bins are constructed using the highest-strength steel available. Sidewall sheets are made from high-tensile steel that is rated up to 70,000 psi (450 MPa) minimum. A commercial G‑90, galvanized steel coating increases life and durability.
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.
Redesigned wind ring and wind ring brackets reduce bolt holes in stiffeners, resulting in increased load capacity. Swaged, bolted splice ensure your 40-Series bins will stand up to the toughest wind conditions.
GSI uses JS500 bolts paired with sealing washers to protect the grain. JJS500 coated hardware provides added protection from rust, promoting longer bin life.
Rolled structural base angle prevents water from entering at the base of the bin for improved protection.
