Rectangular Ductwork
Ask Us About Our NEW 18-Gauge Galvanized Spiral Pipe!
GWSM fabricates rectangular ductwork for our customers for the commercial and industrial HVAC markets. Our Iowa Precision Coil Line allows us to fabricate large volumes of straight ductwork to meet your needs. Our two plasma tables are used to fabricate all the fittings and short lengths of straight ductwork necessary for a complete system to complement our straight ductwork from the coil line. Our Lockformer roll forming machine allows us to install TDC flanges to our rectangular fittings, eliminating the use of costly Ductmate type flanges.
