DUCT G.I S PATTI (S-cleat)

DUCT G.I S PATTI, commonly referred to as Galvanized Iron Strips or Galvanized Iron Sheet Patti, is a crucial component in HVAC (Heating, Ventilation, and Air Conditioning) systems. It is primarily used to construct ducts for air distribution and exhaust systems. The strips are made from galvanized iron, which involves coating the iron or steel with a protective layer of zinc to prevent rusting and corrosion.

A Duct G.I S Patti (S-Cleat) is a galvanized iron (G.I.) sheet metal connector used in HVAC (Heating, Ventilation, and Air Conditioning) duct systems to join two rectangular duct sections together.

Benefits:

1. Corrosion Resistance:
   • The zinc coating provides a durable and long-lasting protective barrier against rust and corrosion, making the ductwork suitable for a wide range of environments, including humid and industrial settings.
2. Durability:
   • Galvanized iron is known for its strength and resilience, ensuring the ductwork can withstand physical impacts and wear and tear over time.
3. Cost-Effective:
   • Compared to other materials, galvanized iron offers a balance between cost and durability, making it an economical choice for large-scale duct installations.
4. Ease of Fabrication:
   • G.I strips are easy to cut, bend, and shape, allowing for custom duct configurations and quick on-site modifications.
5. Fire Resistance:
   • Galvanized iron has a high melting point and does not burn, adding an extra layer of safety in buildings where fire resistance is crucial.
6. Aesthetic Appeal:
   • The shiny surface of galvanized iron provides a clean and professional appearance, which can be important in visible installations.

Additional Features:

1. Compatibility:
   • Compatible with various fittings and fasteners used in ductwork installation, ensuring ease of assembly and maintenance.
2. Environmental Impact:
   • Galvanized iron is recyclable, contributing to sustainability efforts in construction and manufacturing industries.
3. Custom Options:
   • Available in different coatings, such as pre-painted or powder-coated options, for additional protection and aesthetic requirements.
