Galvanized Steel HVAC Duct Flange
Galvanized steel HVAC duct flanges are flat-rolled strips of non-alloy steel, under 600 mm wide, and plated with zinc for corrosion resistance. These flanges are used to connect sections of HVAC ductwork, providing structural strength and a secure fit. They fall under tariff item 7212.30.00 as flat-rolled products otherwise plated or coated with zinc.
