At Keystone Steel Services LLC, we are an AISC-Certified Fabricator. Our team has over 35 years of in-house detailing experience and over 40 years of steel fabrication and erection experience. With detailing, estimating, and erection services, we handle projects between 100 and 1,500 tons of structural steel. We utilize innovative 3D-modeling software to ensure precision and efficiency for each steel project implementation before we begin. Between our on-site services and our capabilities in our 122,000 square foot plant located on 79 acres in Rhome, Texas, there is very little that we cannot accomplish in structural and miscellaneous steel fabrication to serve our customers in the Dallas-Fort Worth metropolitan area, including Arlington, Plano, Irving, Denton, Richardson, Grapevine, and elsewhere in the Southeast.
