Steel tubing company to build a new facility near Cheyenne
A California based company announced that it will expand its operations and build a new facility near Cheyenne.
Searing Industries, based in Rancho Cucamonga, Calif., will construct a new 200,000-square-foot building in the Swan Ranch Rail Park. Workers there will make welded steel tubing.
The rail park, located southwest of Cheyenne and west of Interstate 25, is a Granite Peak Development industrial park.
The plant will have some of the latest equipment like a state-of-the-art tube mill. It converts raw steel material in coil form to round, square and rectangular tubing.
Richardson Construction of Cheyenne, the project’s general contractor, has started to build the new facility. Work should be done in August or September.
The new facility is being built on land served by rail lines. BNSF Railway operates a rail service there now, and Union Pacific Railroad will do so in the future.
