About HSI Systems

HSI Systems (HSI) is a Union Iron Works (Union Iron) brand of galvanized bucket elevators, chain conveyors and structural equipment.  These products target large farms, small commercial facilities and international markets in capacities up to 10,000 BPH.

HSI dates back to the 1940’s when Royce Huss and Jerry Schlieper began manufacturing grain handling equipment in Decatur, IL.

HSI became a well know name in the commercial grain handling and processing industries and in 2001, Union Iron purchased the complete HSI product line. Since then, Union Iron has continued to market distributors and gravity screeners under the HSI brand.

People, Products, Quality

People are the most important part of Union Iron Works. Our customers, prospective customers and employees are the most important thing we deal with. Without them we have nothing. We at Union Iron Works understand that you cannot have a successful company without recognizing and respecting the value and needs of people.

Second to people are product and service. Union Iron Works puts out a quality product, but lets face it, so do a lot of other companies. What makes Union Iron Works products superior? Proper application and over a century of application know-how. We understand that without the proper application, even the best products will not perform well. Our sales and engineering staff is experienced in selecting the proper product for your specific application. This is what makes a Union Iron Works product stand out from the crowd.

The key to Union Irons Works continued success is our ability to provide a complete line of equipment from legs and conveyors to drives and repairs. Our goal is to provide the equipment needed to get the job done right. We also understand that even the best equipment is useless if it is not available when you need it. Our staff works hard to ensure that the equipment you need is there when you need it.
