GI Duct Manufacturers in Pune | Wahed Engineering
GI ducts are air-conveying systems made from Galvanized Iron (GI) sheets — steel sheets coated with a layer of zinc to protect against rust and corrosion. They are widely used in HVAC (Heating, Ventilation & Air Conditioning) systems, industrial ventilation, exhaust systems, air distribution networks, and environmental control applications.
Key Components of GI Duct Systems
- Main ducts: Large primary air passages
- Branches: Smaller offshoots from mains
- Take-offs: Points where air splits to diffusers/grills
- Elbows & Bends: Change airflow direction smoothly
- Reducers & Expanders: Transition sections between sizes
- T-junctions / Tees: Split or join airflow paths
- Flanges & Gaskets: Connect sections with minimal leakage
- Insulation (optional): For thermal control & noise reduction
Types of GI Ducts
- Rectangular GI Ducts
- Circular / Spiral GI Ducts
- GI Flexible Ducts
- Insulated GI Ducts
- Prefab TDF / Pittsburgh Ducts
Advantages of GI Ducts
- Corrosion Resistance: Zinc coating protects against rust
- Strength & Durability: Good structural rigidity
- Fire Resistance: Non-combustible material
- Custom Fabrication: Built to size & layout needs
- Clean Finish: Ideal for exposed areas
- Recyclable Material: Environment-friendly
Common Applications
- Commercial buildings (offices, malls, hospitals)
- Industrial plants & factories
- Clean rooms & laboratories
- Data centers & server rooms
- Exhaust and make-up air systems
- Air handling units (AHUs) & fan systems
