Contact Us
Industrial Screen and Maintenance (ISM) has two locations, the original Machine Shop in Casper, WY since 1969 and a full-service Machine Shop in Grand Junction, CO established 2005. Both facilities have CNC lathes, mills and manual machines with highly trained machinists, welders, and fabricators with decades of experience. ISM carries a large inventory of all common high yield alloys, stainless steel, carbon steel, aluminum, brass, bronze, and copper. This gives us the ability to provide fast lead times, saving you valuable downtime. We differentiate ourselves by providing the most rapid response possible to quotes and inquires.
