40-Series Grain Bin Systems

Higher Capacities and Custom Design Flexibility

Be it food, feed or fuel the need to move grain quickly and efficiently is critical. GSI’s new Z-Tek™ Roof System, with its clarge flat top and higher peak loads support larger material handling equipment, allowing more grain to move into storage faster. Stiffener profile design allows for taller structures while maintaining construction integrity and strength.
