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.
