Product Overview & Key Advantages

High-Performance Surface Coating

PVDF (Fluorocarbon) Coating for Maximum UV Protection

PVDF fluorocarbon coating boasts superior ultraviolet resistance, effectively resisting sunlight fading, aging and discoloration. It maintains stable color tone even under strong solar radiation and extreme outdoor climate, serving long-term exterior building use.

High-Durable Polyester (HDP) for Excellent Weather Resistance

HDP high durability polyester coating features outstanding anti-aging, rain and wind erosion resistance. It balances cost performance and outdoor durability, perfectly fitting conventional architectural exterior decoration demands.

Superior Material Properties

Excellent Formability and Flexibility (No Cracking After Bending)

The aluminum coil owns fine internal texture and great ductility. It supports bending, rolling and cutting processing without paint cracking or peeling, easy for customized shaping and installation.

Light Weight with Structural Strength

Light body effectively reduces building load burden, meanwhile retains solid structural toughness. It won’t deform easily under external force, securing stable use effect for building components.

Outstanding Anti-Corrosion & Rust-Free Performance

Natural anti-rust characteristic of aluminum alloy plus sealed protective coating layer isolate moisture, acid and alkali corrosion. The coil stays rust-free and intact in humid, coastal and corrosive working environment.
