4002: Unstiffened Bins

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.
