High-Quality Base Steel (DX51D to DX56D)
Cold-Rolled Substrate: These coils are based on cold-rolled low-carbon steel (DX series), ensuring a smooth, uniform surface that enhances coating adhesion and final product aesthetics.
Consistent Mechanical Properties: The DX grades offer good formability, ductility, and weldability, making them suitable for various fabrication processes (e.g., bending, cutting, roll forming).
Durable Metallic Coatings (Z, ZA, ZM, AZ)
The "+Z/ZA/ZM/AZ" designations indicate protective metallic coatings applied to the base steel, providing corrosion resistance:
Z (Zinc Coating): A traditional zinc layer that acts as a sacrificial barrier, protecting the steel from rust through cathodic protection.
ZA (Zinc-Aluminum Coating): Contains aluminum (typically 5-15%) in addition to zinc, offering improved corrosion resistance compared to pure zinc, especially in humid or industrial environments.
ZM (Zinc-Magnesium Coating): Includes magnesium (1-3%), which forms a dense, protective oxide layer, enhancing resistance to pitting corrosion and extending service life.
AZ (Aluminum-Zinc Coating): High-aluminum content (e.g., 55% Al, 43.5% Zn) creates a tough, heat-resistant coating, ideal for applications exposed to high temperatures or UV radiation.
Superior Color Coating Performance
Multi-Layer Coating System: Typically consists of a pre-treatment layer (for adhesion), a primer (corrosion resistance), and a topcoat (color and weather resistance). Some variants may include a backcoat for added protection.
Weather Resistance: The topcoat (often polyester, PVDF, or silicone-modified polyester) resists fading, chalking, and degradation from UV rays, rain, and pollution, ensuring long-term color retention.
Wide Color Range: Available in custom colors, finishes (matte, gloss, textured), and patterns, meeting diverse architectural, industrial, or decorative design needs.
