Lightweight Aluminum Steel Coil 900-1800mm Custom Cut HVAC Ductwork Applications
Lightweight Aluminum Steel Coil is engineered for high-efficiency HVAC ductwork, combining the strength of steel with the corrosion resistance and thermal performance of aluminum. Compliant with ASTM A653 and EN 10346 standards, this coil features a 55% aluminum-zinc coating and is available in custom widths from 900mm to 1800mm, with thicknesses ranging from 0.5mm to 2.0mm. Designed for seamless fabrication into air ducts, vents, and exhaust systems, it ensures energy efficiency, durability, and compliance with stringent indoor air quality (IAQ) regulations.
Key Selling Points:
- Optimal Thermal Efficiency: Reflects 80% of radiant heat (ASTM C1371), reducing HVAC energy costs.
- Corrosion Resistance: Aluminum-zinc coating withstands moisture, condensation, and chemical exposure (ASTM B117).
- Lightweight & Durable: 25% lighter than galvanized steel, with tensile strength up to 550 MPa (Grade S550GD).
- Easy Fabrication: Compatible with roll forming, welding, and lock-seam processes for airtight duct systems.
- Eco-Certified: Recyclable, low-VOC, and compliant with LEED v4.1 and WELL Building Standard.
