In an HVAC system there are many times when there is a need for ducts for supplying conditioned as well as fresh air to a particular indoor area from the machine and because of this reason duct system works have gained importance in HVAC system. Ducts are used for heating, ventilation and air conditioning to deliver or remove air. Ducts are available mainly in two types Rectangular and Circular ducts but can be made of different material like G.I Mild steel, Stainless steel and aluminum. Installing Duck work has many advantages like reducing electricity bills by correct channeling and sizing according to the airflow but this can be achieved only with good quality ducts and qualified installation technicians.

The Duct fitting are processed through the CNC controlled Plasma Cutting System. The fabricator feeds the data in the system and the system automatically nests the parts on the sheets with the precise measurements. The Plasma Cutting tables are then loaded with GI steel and the fitting parts are cut. The fabricator identifies the pieces with the help of layouts prints and marks the dimension along with fabrication instructions that deal with bending, rolling, etc. These parts then are passed through duct beader to strengthen the sheets by grooving them.
