Air ducts are an essential part of the heating and A/C system. By 2022, HVAC industry positions are expected to increase by 21 percent. In addition to the need for more technicians, buildings will need more ductwork, which will increase the demand for quality duct fabrication in the future.


With a large capacity of HVAC Ductwork demanding, more and more duct manufacture factories are needed.

Manufacture from raw materials such as galvanized steel, aluminum, stainless steel and mild steel, the products will include Standard Rectangular HVAC Ducts and Fittings, Special Traverse Joint TDF Ductwork for airtight requirements, Fire-rated Ducts to BS:476: Part 24: 1987, Volume Control Dampers, Fire Dampers, VAV Units, Air Filters, Access Doors, Plenum Boxes and Sand Trap Louvers. 

Duct Factory must be quality assurance and control at every stage of manufacture conforming to international processes and standards, highly experienced engineers working with skilled technicians and fabricators-and strict compliance with health, safety and environment norms.
