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.

Core Characteristics

Material: Primarily fabricated from galvanized steel (GI) for corrosion resistance and durability. Stainless steel is used for corrosive environments, while aluminum is chosen for weight-sensitive applications.
Fabrication: Manufactured from flat sheets joined using automated coil lines. Common joints include Pittsburgh locks and various flange systems for transverse connections.
Space Efficiency: The flat-sided profile allows for installation flush against ceilings or within wall cavities, maximizing plenum space.
Insulation: Can be externally wrapped or internally lined to prevent condensation, reduce thermal loss, and dampen noise.

Feature / Aspect	Description & Common Specifications	Typical Application / Note
