RK is the Rocky Mountain Region’s top supplier of mechanical and industrial solutions for construction and commercial applications. RK operates six business units: Mechanical, Service, Steel, Energy, Water and Electrical.

With over 1,200 total employees, our six units often partner on projects, and our combined skill set makes us Colorado’s largest single source for mechanical contracting, manufacturing, steel fabrication, prefabricated construction, facilities maintenance services, electrical expertise as well as water treatment products and solutions.
