Ppgi Ppgl Color Coated Aluzinc Steel Coil

PPGI (pre-coated galvanized steel coil) and PPGL (pre-coated aluminum-zinc steel coil) are core materials in the construction and industrial fields. They give steel excellent corrosion resistance, decorativeness and functionality through advanced coating processes. Our products are based on AZ150 aluminum-zinc alloy coating (55% aluminum + 43.4% zinc + 1.6% silicon)4, combined with environmentally friendly coatings such as PVDF, HDP, and PE, to provide full-scenario solutions from basic anti-corrosion to high-end decoration, meeting international standards such as ASTM A792, JIS G3321, and EN 10346, and adapting to the needs of harsh global environments.

Core competitive advantage

Super corrosion resistance

AZ150 coating: Salt spray resistance of up to 2500 hours (C5 environment)8, with a service life 3-5 times higher than that of ordinary galvanizing, especially suitable for high-corrosion scenarios such as coastal areas and industrial pollution areas.

Double coating system: Galvalume provides long-term protection, and PPGI/PPGL enhances weather resistance. Double protection extends the life of the material to 30 years + 8.

Diverse surface treatment

Coating types: PVDF (fluorocarbon), HDP (high weather-resistant polyester), PE (polyester), to meet different budgets and performance requirements.

Decorative effect: supports 50+ surface textures such as imitation wood grain, stone grain, metal brushing, etc., RAL/Pantone color cards are accurately matched to meet architectural aesthetic design.

Additional functions: antibacterial coating (Ag+ ion), self-cleaning coating (photocatalyst), high reflective insulation coating (Solar Reflective) 8.

Flexible specifications and customized services

Substrate selection: cold-rolled steel coil (DC01-DC06), galvanized coil (Z80-Z275), galvanized coil (AZ50-AZ200).

Size range: thickness 0.2mm-2.0mm, width 600mm-1500mm, supports striping, laminating, punching and other processing312.

Fast delivery: 5 major domestic storage centers have 10,000 tons of spot goods, support 1 roll order, and 72-hour express delivery12.

Environmental protection and cost-effectiveness

Using chromium-free passivation process, VOC emissions are reduced by 90%, meeting LEED green building certification requirements.

Secondary quality is graded and supplied, cost-effectiveness is improved by 20%, and the cost of non-critical structural parts is reduced3.
