GSI’s in-plane roof lap is designed to prevent leaking by eliminating the flashing that is required between the upper and lower panels. Single sheet roofs are standard for all bins up to 78’ diameter. From single-sheet roofs to an overlapped panel design, your crop is protected.
GSI uses JS500 bolts paired with sealing washers to protect the grain. In addition, JS500 coated hardware provides added protection from rust to ensure your grain bin stands the test of time.
A commercial G-90, galvanized steel coating increases life and durability.
Rolled structural base angle prevents water from entering at the base of the bin for improved protection.
In 1972, the first GSI bin featured a 2.66” corrugation, unstiffened bin design. This proven design has continued to evolve and grow for today’s operations, and features our precision roll-forming process corrugates accurate sidewall sheets every time. This process assures a tighter fit and increased weather protection.
With the original 2.66” corrugation profile, the 4002 is the perfect bin to maintain a historic look and consistent bin height.

"We’ve been with GSI since the 1950s"Clint McLeod - BriMac Farms
For the past 20 years, we’ve dried all our corn on farm. We have one of the original TopDry systems. When we are running at our best, we are drying and moving corn quickly. About five years ago we added a loading bin so we could fill a semi in three minutes. It used to take 30 minutes when we used an auger. When we break it down, we can get an extra round a day or so. We are looking to be as efficient as possible, especially knowing our farm is set to continue expanding.Watch Video
