In the field of building enclosure and industrial protection, the weather resistance and decorativeness of materials directly affect the quality of the project. As the world's leading provider of color-coated steel solutions, Yintu Steel has launched a new generation of Galvalume (aluminum-zinc) frosted color-coated coils. Through the perfect combination of 55% aluminum-zinc alloy coating and German embossing technology, it provides a full life cycle protection solution for fences, sandwich walls and other scenes that combines corrosion resistance, wear resistance and aesthetics.
1. Core advantages of Galvalume matte color-coated coils
For outdoor high-corrosion environments and architectural aesthetics, our products have five core competitive advantages:
Super strong anti-corrosion system
55% aluminum-zinc alloy coating (ASTM A792), salt spray test over 3000 hours, corrosion resistance is 3 times that of galvanizing
25μm polyester (PE) / fluorocarbon (PVDF) topcoat, UV absorption rate > 99%
Intelligent surface treatment
German servo embossing technology, forming 0.05-0.1mm three-dimensional matte texture
Anti-slip coefficient μ≥0.70, anti-fouling ability increased by 200%
Precise mechanical properties
Yield strength 245-550MPa (corresponding to DX51D-DX57D)
Elongation ≥12%, suitable for complex modeling processing
Environmentally friendly production process
Chromium-free passivation + water-based paint, passed ISO 14001 and SGS green certification
Pre-coating process reduces on-site pollution and improves construction efficiency 60%
Long-term color management
Color fastness of Japanese Kansai paint is level 7 (ISO 105-B02)
15-year color retention commitment (normal environment)
II. Three major technological breakthroughs of Yintu Steel Industry
Nano-ceramic reinforcement technology
Adding ZrO₂ nanoparticles to the coating increases the hardness to 4H and the wear resistance is improved by 80%
Gradient functional coating
Sandwich structure of epoxy resin primer + intermediate transition layer + frosted topcoat, adhesion level 0
Intelligent embossing system
Servo embossing machine equipped with CCD visual detection to achieve ±0.01mm texture accuracy control
III. Typical application scenarios
