Characteristics：Weather proof; heating insulation; fireproof; anti-rust; sound insulation; long life span: more than 20 years.
Corrosion Resistance: the aluzinc coating surface protects the base steel not only by providing barrier to corrosion elements, but
also by the sacrificial nature of the coating.
01. SMOOTHNESS
No composite indentation, no residual stress, no deformation after shearing.
02. DECORATIVE
You can choose a realistic material and aesthetic wood grain, stone coating. Patterns and colors can be customized according to
customer requirements.
03. DURABILITY
Surface paint, high gloss retention, good color stability, minimal change in chromatic aberration, and long service time.
04. STABILITY
The change of wind pressure, humidity and temperature will not cause bending, deformation and expansion. It has strong bending and flexural resistance.
