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

1. Building enclosure system

Industrial fence: acid-resistant fence of chemical plant, isolation fence of logistics park

Commercial sandwich wall: shopping center exterior wall, hotel modular wall

Public facilities: airport sound insulation wall, subway station enclosure structure

2. Industrial equipment protection

Port machinery protective cover, mining equipment shell

Agricultural greenhouse enclosure, livestock farm ventilation panel

3. High-end decoration field

Villa courtyard fence, resort landscape wall

Art installation surface, commercial space partition
