Spiral & Round Seamed Ductwork

CVS Round Ductwork offers advantages such as faster installation, lower costs, reduced leakage, lower pressure drops, and improved operational efficiency. Spiral wound ductwork and fittings, fabricated to industry standards, are utilized in large-scale projects due to their notably low leakage rates and selfsealing mechanisms.

Round and spiral ductwork are manufactured in standard lock-forming quality using galvanized steel for ventilation applications, with aluminum and stainless steel options available for exposed applications and cladding systems.

Duct construction adheres to DW144, SMACNA, and ASHRAE standards, ensuring superior strength, low leakage rates, and vibration-free products. The diameter of spiral ducts ranges from a minimum of 125mm to a maximum of 3000mm. Individual pipe lengths are available upon request, with options in aluminum and stainless steel.

Seamed pipes are produced in standard lengths of 1220mm, while spiral pipes can be manufactured in lengths of up to 6000mm. Pipes can be fabricated in various gauges, including up to 12g for aluminum, 14g for galvanized steel, and 16g for stainless steel.
