G300 G550 Frosted Pattern Ppgi Ppgl Iron Coil

0.18mm-1mm PPGI color-coated steel coil and Galvalume aluminum-zinc steel strip are advanced materials that combine lightness and high performance, and are designed for fields with strict requirements on thickness accuracy and surface quality.

Substrate selection: cold-rolled steel coil (DC01-DC04), Galvalume aluminum-zinc substrate (AZ50-AZ150, 55% aluminum-zinc alloy coating);

Coating process: PPGI uses PVDF/HDP/PE environmentally friendly coatings with a coating thickness of 10-30μm; Galvalume steel strip retains the natural corrosion resistance of the coating, and the surface can be additionally treated with fingerprint resistance;

Implementation standards: ASTM A755, JIS G3321, EN 10346, adapted to global high-end manufacturing needs.

Four core advantages

Ultra-thin precision processing capability

Thickness tolerance ±0.02mm (0.18mm ultra-thin plate), width striping accuracy ±0.5mm, suitable for precision stamping, laser cutting and other processes;

Plate flatness ≤3I-Units, ensuring high-speed continuous processing without warping.

Long-term corrosion protection

Galvalume coating: bare plate salt spray resistance ≥1500 hours (C4 environment), life is 4 times longer than ordinary galvanizing;

PPGI coating: PVDF coating is resistant to ultraviolet aging for 4000 hours (△E≤2), suitable for outdoor decoration and building enclosure.

Diverse surface treatment

Decorative: matte/high gloss/textured coating, RAL color card 200+ colors optional, support imitation wood grain, stone grain customization;

Functionality: antibacterial coating (99% antibacterial rate), self-repairing coating (micro scratch self-healing), high reflective coating (reflectivity ≥85%).

Environmental protection and economic benefits

Using chromium-free passivation + water-based coating technology, passed REACH and RoHS environmental certification;

Ultra-thin design reduces material usage and reduces overall costs by 15%-30%.
