ESI not only designs and builds top-quality commercial grain storage solutions, but we also outfit them with the best material handling systems available.
Hawthorne-Seving, Inc. (HSI), our material handling manufacturing company, was founded in 1949 and acquired by ESI in 1980. HSI manufactures heavy commercial drag, belt, and screw conveyors, along with bucket elevators, barge spouts, gates, and much more. Our material handling equipment is ideal for heavy-volume applications.
