Product Introduction
For industrial exhaust and HVAC systems, CNB supplies heavy‑gauge aluminized steel pipes that handle hot gases and corrosive fumes. Common applications include factory smoke exhaust, drying oven ducts, boiler flue pipes, and high‑temperature ventilation in commercial buildings. Our pipes withstand continuous temperatures to 450°C without scaling, and the aluminum‑silicon coating provides superior protection against sulphur compounds in flue gases.
