Engineered for durable HVAC performance, this 4-inch diameter, 10-foot long spiral pipe is constructed from 26-gauge galvanized steel. The pipe features a robust 4-ply spiral lockseam, delivering superior resistance to crushing forces—approximately 2.5 times greater than longitudinal lockseam or welded alternatives. Its smooth interior promotes low friction loss, making it ideal for efficient air distribution in both residential and light commercial ductwork.
