Standard Tinsmith Supply

Standard Tinsmith Supply, established in 1914, has proudly remained a family-owned and operated business for over years—carrying the same name, values, and dedication through four generations. Serving the HVAC trade with an unwavering commitment to quality, we specialize in sheet metal, spiral duct, flat oval spiral duct, and all the essential accessories including insulation, canvas connectors, adhesives, and mastics. At Standard Tinsmith, we take pride in the honesty and integrity that define both our products and our service. We believe in a simple but powerful philosophy: the better we do for our customers, the better we all do. It’s this principle that has earned us the trust of contractors, fabricators, and mechanical professionals for over a century—and why we continue to set the standard today.
