AccuDuct Manufacturing began providing products to the HVAC industry in 1987. Since then, we have grown from a local spiral p ... ipe and fitting supplier to a nationally recognized, leading manufacturer of labor saving duct systems and sheet metal components. We are motivated by customer satisfaction and continually strive to deliver competitively priced, high quality products on the tight schedules demanded on today's construction projects. We don't shy away from a challenge. In fact, our impressive range of spiral sizes (1" through 120" diameter) came about by meeting the demands of some very unique projects. From exposed spiral pipe and fittings in a high school gymnasium to fully welded, heavy gauge, industrial solvent exhaust in a state-of-the-art microchip manufacturing plant, we offer round, oval and rectangular duct systems for a wide variety of commercial and industrial applications. Our experienced sales engineers work closely with our customers at each stage of the project to insure their complete satisfaction. read more
