Wisconsin-based materials handling and industrial storage specialists Wolter Inc. has expanded its capabilities with acquisition of Illinois-based CSI Materials Handling.

CSI Materials Handling is a provider of pallet racking, engineered storage systems, and installation services. 

Wolter states that acquisition strengthens its presence in the Chicago market and expands its ability to support growing demand for warehouse capacity from 3PL and distribution operations.

“The addition of CSI Materials Handling enhances our ability to support customers across the full warehouse lifecycle,” says Jerry Weidmann, CEO of Wolter Inc. 

“By adding experienced engineering and installation capabilities, we can help customers move faster from design to execution as they expand and optimise their warehouse operations.”

CSI was founded in 1969 and has become a long-standing provider of industrial storage solutions across the greater Chicago area.

"With this acquisition, Wolter deepens its ability to deliver complete warehouse solutions, combining narrow-aisle equipment, layout design, storage systems, and installation services,” Wolter states. “This positions the company to better support Chicago-metro businesses looking to increase warehouse capacity and improve operational efficiency.”

CSI Materials Handling will continue to operate from its Downers Grove, Illinois location with its full complement of staff joining the Wolter team.

Wolter finished 2025 announcing its expansion into the Carolinas with the acquisition of Carson Industries.
