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.
Technical Specification
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 with Pittsburgh locks for longitudinal seams and advanced flange systems.
• Space Efficiency: Flat-sided profile allows flush installation against ceilings or within wall cavities.
• Insulation: Compatible with fiberglass blanket or acoustic liners to prevent condensation and reduce noise.
