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. Stainless steel or aluminum options available for specialized environments.
Fabrication: Manufactured from flat sheets joined using automated coil lines, Pittsburgh locks, and various flange systems.
Space Efficiency: Flat-sided profile allows installation flush against ceilings, maximizing plenum space.
Insulation: Can be externally wrapped or internally lined for thermal and acoustic management.

Feature / Aspect	Description & Specifications	Typical Application
Primary Material	Galvanized Steel (GI), Stainless Steel, Aluminum	GI is standard for general HVAC.
Standard Gauge	0.5mm to 1.5mm or thicker	Governed by SMACNA standards.
Connection Systems	TDF, Angle Iron Flange, S&D, Standing Drive	TDF is modern airtight standard.
Key Strength	High Rigidity	Medium to high-pressure systems.
Air Leakage Class	Class 1, 2, or 3 achieved with gasketed flanges	Critical for energy efficiency.
Primary Use Cases	Office buildings, hospitals, schools, retail	Dominant choice for space constraints.
