Product Description

A metal rectangular duct is a fundamental component in Heating, Ventilation, and Air Conditioning (HVAC) systems, designed for the controlled conveyance of air in commercial, institutional, and industrial buildings. Its defining characteristic is its cross-sectional shape, which offers significant advantages in spatial planning and structural integration compared to round ducts.

Primary Function: To efficiently transport supply (conditioned) air, return air, or exhaust air throughout a building with minimal air leakage and pressure loss.

Specification

Material: Primarily fabricated from galvanized steel (GI) for corrosion resistance. Stainless steel is used for corrosive environments or kitchen exhaust.
Fabrication: Manufactured from flat sheets that are cut, notched, folded, and joined using automated coil lines.
Space Efficiency: Flat-sided profile allows installation flush against ceilings, maximizing plenum space.
Insulation: Often externally wrapped with fiberglass or lined internally to prevent condensation and dampen noise.
