General Sheet Metal Works, inc. is a full line metal service and retail metal supply center that serves Northeast Iowa.

We offer a well-stocked retail center and warehouse filled with an extensive selection of metals. Our customer list has grown to over 500 companies in the Northeast Iowa region. We are consistently told that the personal service GSM provides is unique in the custom fabrication industry and that is what keeps them coming back year after year. We welcome your inquiries regarding metal supply and fabrication, and are ready to serve you at any time.

GSM has roots dating back to 1915, when it was one of Waterloo, Iowa’s early fabricators. The company was then known as Moore Manufacturing. Our founder, Walter M. Widmann worked as a foreman for Moore Manufacturing for many years before purchasing the business. The company was incorporated as General Sheet Metal Works in 1956 and has been operating as GSM ever since. It is currently at the same 217 Rath Street location next to the 18th Street bridge in Waterloo.
