Primary Aluminium Coil

Pre-Painted Galvanized Steel Sheet (PPGI) is a high-performance color-coated steel product made by applying paint coatings on a galvanized steel (GI) substrate through a continuous coil coating process. It combines excellent corrosion resistance with aesthetic flexibility, making it ideal for architectural, industrial, and appliance applications.

 

Galvalume Steel (AZ/GL):The coating is precisely composed of 55% aluminium, 43.4% zinc and 1.6% silicon. Verified by professional tests, its corrosion resistance is 3 to 6 times that of ordinary galvanized steel plates. Its unique alloy composition endows it with a thermal reflectivity of up to 75% and excellent oxidation resistance. Whether it is the building roof exposed to the scorching sun for a long time, the exterior wall that needs to resist wind and rain erosion, or the manufacturing of automotive parts with extremely high durability requirements, it can handle them all with ease. Even under harsh climatic conditions, this material still maintains excellent molding processing performance, ensuring a service life of over 20 years in most environments. It is an ideal choice for projects that pursue long-term protection and energy-saving performance.

Galvanized Steel (GI):Coated with zinc layers of different sizes Z60-Z275, it offers reliable rust protection at a highly competitive cost. With its excellent weldability and formability, it is widely used in the construction of building structures, the manufacturing of agricultural machinery and equipment, the production of electrical equipment enclosures, and the installation of fences, among other fields. The sacrificial anode protection mechanism of the zinc coating can actively consume itself to protect the base steel when scratches or damages occur on the surface of the steel plate, maintaining the structural integrity. Depending on the differences in environmental conditions, its service life usually fluctuates between 15 and 50 years, making it a basic protective material that is both economical and practical.

Aluminum Coil/Pipe/Plate:We offer a variety of aluminum alloy products ranging from 1000 to 6000 series, achieving a perfect balance between strength and weight, and featuring natural corrosion resistance. With an outstanding thermal conductivity of 235 W/m · K and non-magnetic properties, it is the ideal choice for applications such as aerospace components, automotive parts, heat exchangers, and food packaging. Customized through different processing states such as O, H12, and T6, the product not only maintains the advantage of being lightweight but also features remarkable durability, fully meeting the diverse performance requirements of various industries for aluminum products.

Stainless Steel:Different grades such as 304, 316, and 430, providing unparalleled hygiene standards and corrosion resistance for high-demand application scenarios. The oxide film rich in chromium can effectively resist pitting and crevice corrosion even in high salt spray environments such as the ocean. Among them, 304 stainless steel can withstand temperatures as high as 870°C (1600°F), making it a key material for food processing equipment, medical devices, chemical container manufacturing, and architectural decoration projects that pursue both strength and aesthetics, providing comprehensive protection for equipment safety and environmental cleanliness.

Aluzinc Steel (AZ) : The AZ150-AZ200 specification aluminized zinc steel, with the zinc-aluminum alloy coating, significantly outperforms traditional galvanized steel in terms of heat resistance (up to 315°C/600°F) and anti-corrosion performance. The unique coating structure forms a solid barrier, effectively inhibiting the formation of red rust. It is particularly suitable for scenarios with strict requirements for durability and thermal performance, such as industrial plant roofs, agricultural buildings, and solar panel frames, providing stable performance to facilitate the long-term efficient operation of projects.

Prepainted Steel (PPGI/PPGL) : Color-coated steel plates are pre-coated with high-performance coatings such as PVDF, polyester or HDP before leaving the factory. They not only have bright and long-lasting colors but also excellent weather resistance. The advanced coil coating process ensures that the 20-30 μm coating is evenly covered and has excellent adhesion, achieving a color retention effect of 10-25 years. It supports full RAL color system customization and offers special surface treatment options such as embossing and anti-fingerprint. It is widely used in building exterior wall decoration, high-end home appliance shells, and interior decorative panels, perfectly integrating practical functions with aesthetic design.
