In 1973, friends Bill Tolbert and Warren Smith opened an 800-square-foot job shop in east Tulsa. They provided sheet metal fabrication and welding services for a few customers, working tirelessly to keep their business growing. By 1975, their hard work and reputation for quality allowed them to construct an 8,000-square-foot building on 3.75 acres at S&T's current facility in Catoosa, Oklahoma. By 1980, Smith retired, selling his share of the growing company to his partner's sons, Gary and Ron Tolbert. 

S&T has developed a quality welding system that we can construct to AWS D1.1, ASME Section VIII Division 1, Section 1 and ASME B31.1 for shop and field locations. We hold an ASME "U" and "S" stamp and under the NBIC "R" stamp.  S&T Manufacturing's vast Tulsa campus includes seven on-site buildings  One sheet metal shop with laser, CNC plasma, and rolling capabilities Five fabrication shops with carbon, stainless, or aluminum capabilities One machine and mill shop with multiple CNC machines One paint and coatings shop While capable of being a traditional "job shop", some 90% of all S&T work is authentic turnkey: from prototypes to full production of large inventory, most jobs remain in our facilities from start to finish.
