Superior Substrate Performance
Base Steel Grade (TDC51D/52D/53D/54D): These are cold-rolled or hot-dip galvanized steel grades optimized for forming and coating. They offer excellent ductility, ensuring easy bending, stamping, and processing without cracking, making them suitable for complex shapes.
Consistent Mechanical Properties: The substrates provide stable tensile strength and yield strength, adapting to various structural and load-bearing requirements in different applications.
Multi-Layered Protective Coatings (Z/ZA/ZM/AZ)
The "+Z+ZA+ZM+AZ" designations refer to different zinc-based coating technologies, enhancing corrosion resistance:
Z (Galvanized): A layer of pure zinc coating provides basic corrosion protection, forming a barrier against moisture and oxygen.
ZA (Zinc-Aluminum): Alloy coating with zinc and aluminum (typically 5% Al) improves adhesion and resistance to atmospheric corrosion, especially in humid or industrial environments.
ZM (Zinc-Magnesium): Zinc-magnesium alloy coating (e.g., 3% Mg) offers enhanced anti-corrosion performance, with better scratch resistance and self-healing properties for minor damage.
AZ (Aluminum-Zinc): High-aluminum coating (e.g., 55% Al, 43.5% Zn) provides superior heat resistance and durability, ideal for high-temperature or outdoor applications (e.g., roofing, cladding).
Durable Color Coating
High-Quality Paint Layers: The color coating consists of a primer, topcoat, and optional clear coat, ensuring:
Weather Resistance: Resists fading, chalking, and peeling under UV radiation, rain, and extreme temperatures.
Chemical Resistance: Withstands exposure to acids, alkalis, and industrial pollutants, maintaining surface integrity in harsh environments.
Aesthetic Versatility: Available in a wide range of colors, finishes (matte, glossy, textured), and custom designs, meeting both functional and decorative needs.
Long Service Life
The combination of zinc-based protective coatings and color layers extends the product’s lifespan significantly, often exceeding 15–30 years in outdoor applications (depending on coating thickness and environment), reducing maintenance and replacement costs.
