Welding works on gas pipeline — Gas well products in Gillette, WY
Tri-State Industries is a family owned and operated company in Gillette, WY, started by Jerry Hagen. Jerry focused on insulation but quickly began providing quality fiberglass and steel products too.

Duane Hagen took over for Jerry in the late 90s and incorporated gas measurement and fabrication to the TSI product line.

In 2011, Vice President Vince Spalding assumed operating responsibilities for Tri-State Industries. Vince uses his talents and work ethic to drive our team's reliability, quality, and safety. He is currently focusing on expanding our fabrication line and vapor recovery.

From day one, our mission has been to provide an unrivaled experience in customer satisfaction, product quality, and integrity. Our competitors might have similar products and services, but they can't provide them the TSI way. Call 307-682-9730 to experience service that's second to none.

Oklahoma Location

Tri-State Industries opened a second location in Tulsa, OK to serve our customers better, and to keep up with the growing energy industry. Our Oklahoma location specializes in gas measurement equipment but can help with any of TSI's products or service. With a combined experience of 30 years, Rich & Gretchen run the second office location just as great as our headquarters in Wyoming.
