GI Ducting

A GI duct is galvanized iron metal sheet-made air duct used for the circulation of air to conditioned or specified. It is used in the heating, ventilation and air-conditioning ( HVAC) of multi-rise buildings, mega malls, hospitals, industries, airports, and others by using AHREA and SAMACNA standards internationally. The full form of GI Duct is galvanised iron duct. GI DUCT MEANING DESIGN SIZES AND GAUGE CHART are pillar content in the understanding of GI Duct installation. these are the following types of the duct as per design standards.

• Supply air duct

• Return air duct 

• Exhaust air duct

• Fresh air duct

GI Duct Shapes

As per requirements, duct shapes are different like

• Round air duct

• Rectangular air duct

• Oval air duct

GI Duct Components

GI There are several components to ducts, including outlet diffusers, air dampers, and air filters. A diffuser distributes air into a conditioned space, while an air damper regulates the flow of air.

 In order to prevent airborne illness and improve air quality, air filters are essential. GI ductwork can be designed and installed properly to ensure effective air distribution and reduce energy consumption. The correct air velocity must also be achieved by properly designing and installing duct components.

GI Duct Joints

There are the following types of GI duct joints from a fabrication point of view.

1. Slip Joint

2. Standing Seam Joint

3. Drive Cleat Joint

4. Flanged Joint
