High Quality Thickness Mill Finish Aluminum Coils

In the fields of modern architecture and industrial manufacturing, higher requirements have been put forward for the durability, aesthetics and processing adaptability of materials. PPGI (Polyester Pre-Painted Galvanized Iron) color-coated galvanized steel coils, with their advanced technology and outstanding performance, have become the ideal choice for many projects and are widely used in various fields such as building envelope, home appliance manufacturing, and furniture decoration.

Alloy technology builds long-lasting protection

The coating of Galvalume Steel is composed of 55% aluminium, 43.4% zinc and 1.6% silicon. The unique alloy ratio makes its corrosion resistance 3-6 times that of Galvanized Steel, with a thermal reflectivity of up to 75%, effectively resisting high temperatures and oxidation. Even in harsh environments, it can still maintain a service life of more than 20 years and is often used in building enclosures and automotive parts manufacturing, providing long-lasting and stable protection for products.

A reliable choice of classic craftsmanship

As a basic protective material, Galvanized Steel uses a mature hot-dip galvanizing process, and the surface zinc coating (Z60-Z275) effectively shields against external erosion. With excellent weldability and formability, it is widely used in building structures, agricultural equipment and other fields. The sacrificial anode protection mechanism of its zinc layer can ensure the integrity of steel structures even when damaged, making it a cost-effective anti-rust choice.

Lightweight and high strength open up diverse applications

Aluminum Coil/Pipe/Plate covers alloy products of the 1000-6000 series. Its density is only 1/3 of that of steel, but it has an excellent strength-to-weight ratio. With a high thermal conductivity of 235 W/m · K and non-magnetic properties, it plays a key role in fields such as aerospace, automotive manufacturing, and heat exchangers. Customized through different processing states such as O, H12, and T6, it meets the diverse requirements for material performance in various scenarios.

The quality leader in the high-end field

Products of grades such as 304, 316 and 430 of Stainless Steel, with the oxide film rich in chromium element, have extremely strong corrosion resistance and oxidation resistance, and can remain smooth even in high salt spray environments such as the ocean. Grade 304 can withstand a high temperature of 870°C and is widely used in food processing, medical devices, architectural decoration and other fields. With its outstanding hygiene standards and aesthetic appeal, it has become an essential material for high-end projects.

An economical choice for performance upgrade

Aluzinc Steel, like Galvalume Steel, is a zinc-aluminum alloy coated Steel, but it has been further optimized in terms of heat resistance (up to 315°C) and corrosion resistance, surpassing traditional Galvanized Steel. The unique coating structure effectively inhibits the formation of red rust and is suitable for scenarios with high requirements for durability and thermal performance, such as industrial roofs and solar frames, achieving a good balance between performance and cost.

A creative carrier empowered by color

Prepainted Steel is pre-coated with high-performance coatings such as PVDF, polyester or HDP, and undergoes an advanced eight-coat and eight-bake process to ensure uniform coating and strong adhesion. Supports full-color customization and special texture processing. The color retention ΔE is ≤0.8, and the outdoor weather resistance life can reach 30 years. It is widely used in the exterior walls of buildings, interior decorative panels, etc., deeply integrating functionality and artistry, and injecting unique charm into the space.
