The original IBC (Intermediate Bulk Container) was made from plywood in 1937 for the storage and handling of flour for the milling industry. After WWII the Seattle area originators formed a partnership with Beatrice Steel Tank in Nebraska. The first metal containers were made from aluminum in 1948. The side door design allowed for the discharge of almost any powder including those with poor flow characteristics.

CPS has a registered manufacturing Number “M5730”. It allows us to design and build Dry material handling Bins labeled as CFR49 UN11B Group Y DOT Title 49 Compliant, for Hazardous and Regulated materials shipping over the highway system.

A pivoted hopper discharge was designed to match the bin’s door area and was used for 2-3 years until a new tilting discharge hopper design improved the sealing and dust control. The tilting discharge or stationary hopper was used for many years and worked very well until the bins became dented and worn making them hard to seal.

Bottom discharge units were also designed using a transition hopper from the rectangular body down to a discharge valve. This design virtually eliminated the problem of dust control and allowed for the discharge to close against the flow of product.
