0.09–3.8mm Hot Dipped Galvanized Steel Coil 40–450g/m² for HVAC Ductwork and Ventilation System Fabrication
1. Product Overview
Hot dipped galvanized steel coils are produced by immersing cold rolled steel into molten zinc to form a protective coating layer. This zinc layer improves resistance to corrosion in environments where moisture, airflow, and temperature variation are present, such as HVAC and ventilation systems.
In duct manufacturing and air system fabrication, coating uniformity, forming performance, and dimensional stability are key factors. Coil supply supports efficient downstream production through slitting and cut-to-length processing.
2. Technical Solution
The product performance is based on:
Yield strength 195–420 MPa ensures structural stability, while elongation 12–25% supports bending, rolling, and locking operations in HVAC fabrication.
