Mid-States Spiral is a division of SSM Industries, Inc. supplying the HVAC airside industry with Lindab spiral duct & fittings, along with Gripple hanging products, a labor saving cable hanging system for all mechanical and architectural products and equipment. With SSM Industries, Inc.'s plant as one of the largest sheet metal manufacturing shops in the area and Lindab off the shelf product line, we have the capability to satisfy all your rectangular & specialty duct fitting needs on schedule.

Mid-States Spiral can offer a complete duct system from beginning to end. We offer design & sizing assistance for your convenience.

Lindab duct systems consist of round and oval, single and double wall duct systems including silencers, dampers and grilles. Our round duct systems are equipped with
Lindab Safe EPDM double lipped gasket seals rated to 10” static pressure. This leads to shorter installation times, less weight, fewer air leaks and a smaller insulation surface as well as lower energy consumption. In addition, there are the major advantages for the installation contractor of having locally stocked and standardized products. To complete the spiral line we offer Flat Oval pipe & fittings, along with Insulated Round & Flat Oval pipe & fittings.

Gripple Hangers are universally recognized as the world’s fastest and most cost effective hanger system. The product is used for suspending and bracing of ductwork, piping, electrical and architectural components, as well as Seismic design restraint devices. Gripple Hangers are used on major projects worldwide, covering industrial buildings, distribution centers, schools, hospitals, warehouses, and retail stores. In fact, they can be found in some of the most prestigious projects around the world.
