It means the ductwork is fabricated and installed according to the rigorous standards set by the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA). This governs material thickness (gauge), seam types, reinforcement, and supports, ensuring a high-quality, durable, and low-leakage system.
Galvanized steel (GI) is the most common and cost-effective material for commercial HVAC applications. It offers excellent strength and corrosion resistance. For applications with moisture or chemical exposure, stainless steel or aluminum may be used.
Welded seams are required by the NFPA 96 fire code for grease ducts to create a continuous, liquid-tight enclosure. This prevents highly flammable grease from leaking out of the ductwork and creating a serious fire hazard within the building's walls and ceilings.
