Industrial Prefabrication

Expanding our prefabrication techniques to work smarter, faster and safer.

To meet the demands of the greater Northwest Indiana and Joliet industrial corridors, AMS has strategically located its industrial fabrication facility in East Chicago IN. This facility is comprised of 60,000 ft2 of conditioned fabrication space with additional adjacent buildings to facilitate storage, lay down, prep and painting (special coatings) as required. This combined with the corporate facilities located in Woodridge, IL, which primarily serves our commercial piping, plumbing, and sheet metal fabrication, provides a total of 160,000 ft2 of qualified fabrication space to better serve our clients and meet all of our corporate fabrication requirements. Each facility operates under the U.A. National Pipe Fabrication agreement and fully utilizes blended crews bringing significant cost and scheduling value to project delivery.
