High-Quality Base Steel Substrate
DX51D/53D/54D/55D/56D Series: These are cold-rolled low-carbon steel grades (EN 10346 standard) with precise thickness control and uniform mechanical properties. They offer good formability, weldability, and ductility, making them suitable for various processing methods such as bending, stamping, and roll forming.
Consistent Surface Quality: The base steel has a smooth, defect-free surface, ensuring strong adhesion with subsequent coatings and minimizing the risk of peeling or corrosion.
Multi-Layer Protective Metallic Coatings
The "+Z+ZA+ZM+AZ" designations refer to different zinc-based or zinc-alloy coatings applied to the base steel, providing enhanced corrosion resistance:
Z (Zinc Coating): A pure zinc layer that acts as a sacrificial anode, protecting the steel from corrosion through cathodic protection. It is cost-effective and widely used in general environments.
ZA (Zinc-Aluminum Alloy Coating): Typically contains 5% aluminum and trace elements (e.g., silicon). It offers better heat resistance and corrosion resistance than pure zinc, suitable for moderately harsh environments (e.g., industrial areas).
ZM (Zinc-Magnesium Alloy Coating): Contains magnesium (usually 1-3%) and aluminum, forming a dense corrosion-resistant film. It provides 2-5 times higher corrosion resistance than pure zinc, ideal for humid or coastal areas.
AZ (Aluminum-Zinc Alloy Coating): Composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. It forms a tough aluminum oxide layer, offering exceptional atmospheric corrosion resistance and heat reflectivity (up to 315°C), suitable for high-temperature or outdoor applications (e.g., roofing, solar panel supports).
Durable Color Coating
Polyester (PE), PVDF, or Other Resin Layers: The top color coating is made of high-performance resins (e.g., PE for general use, PVDF for extreme weather resistance). It provides vibrant, long-lasting colors with excellent UV resistance, fade resistance, and weatherability (up to 15-30 years of service life depending on the resin type).
Customizable Finishes: Available in various textures (smooth, embossed, matte) and colors (RAL or custom shades), meeting both aesthetic and functional requirements for architectural, automotive, or industrial applications.
