High-Strength Substrate with Graded Performance
Steel Grade Differentiation (TS280GD/350GD/550GD): These grades are defined by their yield strength (280MPa, 350MPa, 550MPa), offering tailored mechanical properties:
Progressive Strength: Higher grades (e.g., TS550GD) provide superior load-bearing capacity, making them suitable for structural components like heavy-duty roofing, support frames, or high-rise cladding. Lower grades (e.g., TS280GD) balance strength with enhanced formability for intricate designs.
Consistent Toughness: All grades maintain excellent ductility, enabling bending, rolling, and stamping without cracking—critical for manufacturing complex shapes in prefabricated buildings or industrial parts.
Structural Reliability: Designed to withstand dynamic loads, vibrations, and environmental stress, ensuring long-term stability in both static and dynamic applications.
Advanced Zinc-Based Protective Coatings (Z/ZA/ZM/AZ)
The "+Z+ZA+ZM+AZ" suffix denotes a range of zinc-alloy coatings, each optimized for specific corrosion resistance needs:
Z (Hot-Dip Galvanized): A pure zinc coating forms a sacrificial barrier against rust, ideal for general-purpose protection in moderate environments (e.g., indoor storage, non-coastal areas).
ZA (Zinc-Aluminum): Zinc-aluminum alloy (typically 5% Al) enhances adhesion and resistance to atmospheric corrosion, performing well in humid, industrial, or urban settings with air pollution.
ZM (Zinc-Magnesium): Zinc-magnesium alloy (e.g., 3% Mg) delivers exceptional anti-corrosion performance, with improved scratch resistance and self-healing properties—minor scratches trigger a protective oxide layer, preventing further degradation.
AZ (Aluminum-Zinc): High-aluminum coating (55% Al, 43.5% Zn, 1.5% Si) offers superior heat resistance (up to 315°C) and durability, making it perfect for high-temperature applications (e.g., solar panel frames, industrial chimneys) and coastal regions with salt spray exposure.
Durable Color Coating System
Multi-Layer Paint Structure: Comprises a corrosion-resistant primer, a weatherproof topcoat, and an optional clear coat, ensuring:
Weather Resistance: Resists UV-induced fading, chalking, and peeling, maintaining color integrity even in extreme climates (intense sunlight, heavy rain, or freezing temperatures).
Chemical Resistance: Withstands exposure to acids, alkalis, and industrial chemicals, preserving surface quality in factories, laboratories, or coastal areas.
Aesthetic Flexibility: Available in a vast spectrum of colors, finishes (glossy, matte, textured), and custom patterns (wood grain, stone effect), meeting both functional and decorative requirements.
