Frosted Pattern Color Coated Steel Galvalume Coil

In the field of modern building roofs, the mechanical properties and decorative properties of materials are facing dual challenges. As Asia's leading color-coated steel manufacturer, Yintu Steel Products has launched a new generation of G300/G550 high-strength PPGI (galvanized)/PPGL (aluminum-zinc) frosted color-coated coils. Through the ultimate breakthrough of yield strength of 550MPa and innovative surface treatment technology, it provides "rigid and flexible" roof solutions for industrial plants, commercial complexes, high-end residences, etc.

1. Core advantages of G300/G550 high-strength frosted color-coated coils

For high wind pressure, multi-corrosive environment and personalized design requirements, our products have five core competitiveness:

Super strong mechanical properties

G300: yield strength ≥300MPa, elongation ≥18%, suitable for large-span roofs

G550: yield strength ≥550MPa, elongation ≥12%, meet the needs of heavy-loaded roofs

Dual anti-corrosion system

PPGI: 85-150g/m² galvanized layer + 25μm polyester topcoat, salt spray test over 2500 hours

PPGL: 55% aluminum zinc layer (AZ150), corrosion resistance is 3 times that of galvanizing

Frosted surface innovation

German embossing technology, forming 0.05-0.1mm three-dimensional texture

Anti-slip coefficient increased by 40% (μ≥0.65), anti-fouling ability increased by 2 times

Environmentally friendly production process

Chromium-free passivation + Water-based paint, ISO 14001 and SGS green certification

Pre-coating process reduces on-site pollution and improves construction efficiency by 60%

Color durability 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 products

Nano-particle enhancement technology

Adding SiO₂ nano-particles to the coating increases the hardness to 4H and the wear resistance by 70%

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 inspection, achieving ±0.01mm Texture precision control

III. Typical application scenarios

Industrial buildings: acid-resistant roofs of chemical plants, insulation roofs of cold storages, and large-span roofs of logistics warehouses

Commercial landmarks: characteristic roofs of shopping centers, artistic roofs of hotels

Public facilities: curved roofs of airport terminals, canopies of high-speed rail stations

High-end residences: sloping roofs of villas, landscape roofs of resorts
