Industrial advantages of aluminium coils in thermal insulation/fireproof structures

Excellent thermal conductivity control After surface polishing or coating treatment, aluminium coils can reflect over 80% of radiant heat. When combined with rock wool or aerogel, aluminium coils act as a barrier layer with a thermal conductivity as low as 0.05 W/(m·K). In cold chain logistics warehouses, using an aluminium coil + polyurethane sandwich panel solution for roof insulation achieves 40% energy savings.

Superior fire-retardant mechanism Aluminium has a melting point of approximately 660°C, but its self-protective oxide layer (Al₂O₃) slows down fire spread, meeting A2 fire-resistance standards (EN 13501-1). Unlike PVC and other plastic materials, aluminium coils do not release harmful gases when burning, making them suitable for public spaces such as hospitals and subways.

Superior corrosion resistance and longevity The dense oxide layer on the surface of aluminium coils resists acid rain and salt spray (passing the ISO 9227 salt spray test for 5,000 hours). Anodising and fluorocarbon coating further extend the lifespan to over 30 years, reducing maintenance costs.
