Aluminum foil coils and aluminum coils

Q235 PPGI color-coated steel sheet takes Q235 steel as the base material and combines hot-dip galvanizing process with PPGI (polycoated galvanized sheet) technology to achieve a perfect unity of protection and decoration. The hot-dip galvanized layer forms a dense zinc-iron alloy layer. According to the GB/T 13912 standard, the adhesion of the zinc layer reaches grade 1, effectively resisting atmospheric corrosion and prolonging the service life of steel. On this basis, the pre-coated organic coating uses internationally renowned brand paints such as PPG, and through multiple roller coating processes, the coating thickness is precisely controlled and uniform adhesion is achieved. The coating has excellent weather resistance, wear resistance and chemical corrosion resistance. It has been tested in accordance with the AAMA 2604 standard and can ensure color stability and coating integrity for more than 15 years. The products are widely used in the roofs and walls of industrial plants and civil residences, the shells of home appliances and the panels of furniture, etc., meeting diverse demands with reliable performance and rich colors.

Galvalume Steel: By using the hot-dip galvanizing process, aluminum, zinc and silicon alloys are fused onto the surface of steel plates to form a unique "honeycomb" alloy coating. This structure endows it with excellent corrosion resistance. Verified by the ISO 9227 salt spray test, the corrosion resistance life can reach 3 to 4 times that of traditional galvanized steel plates. It also has excellent high-temperature resistance and can remain stable in a high-temperature environment of 350℃. Its smooth and dense surface not only provides an ideal base for subsequent coating but also endows the product with excellent processability and formability. It plays a significant role in fields such as home appliance manufacturing, automotive parts, and building envelope structures, making it the preferred material for projects that pursue high performance and long service life.

Galvanized Steel: A basic anti-corrosion barrier is built by coating a layer of zinc on the surface of steel sheets through mature hot-dip galvanizing or electro-galvanizing processes. The improved Senjimir hot-dip galvanizing process, with the aid of an AI intelligent temperature control system, keeps the temperature fluctuation of the zinc liquid within ±1℃, ensuring a uniform and dense zinc layer and forming a solid alloy layer with the steel base. The product features excellent cold-bending formability and weldability, and can be easily processed into various complex shapes. It is widely used in construction scaffolding, ventilation duct systems, household hardware and other fields. With stable and reliable performance and an affordable price, it has become an indispensable commonly used material in infrastructure and industrial production.

Aluminum Coil/Pipe/Plate: Made from pure aluminum or high-performance aluminum alloys, it stands out in the field of metallic materials due to its light weight and high strength. Aviation-grade 6061 and 7075 aluminum alloys, after undergoing special heat treatment processes, can achieve tensile strength of 310-580 mpa, while their density is only one-third that of steel, effectively reducing the structural self-weight by more than 40%. The surface is treated with technologies such as anodic oxidation and micro-arc oxidation to form a dense oxide film layer, with salt spray resistance exceeding 1,200 hours. It is particularly suitable for scenarios with strict anti-corrosion requirements such as Marine engineering, chemical equipment, and food packaging. In addition, its excellent thermal conductivity, electrical conductivity and 100% recyclability are in line with the concepts of green environmental protection and sustainable development, and have broad application prospects in emerging industries such as new energy and electronics.

Stainless Steel: Alloying elements such as chromium and nickel are added to form a stable passivation film on the surface of steel. It has extremely strong corrosion resistance and oxidation resistance, and can remain shiny and new for a long time even in harsh environments such as dampness, acid and alkali. The AOD-VOD double vacuum refining technology was adopted to control the impurity content in the steel below 0.015%, ensuring the integrity and density of the passivation film. Different models (such as 304, 316, 904L, etc.) optimize performance for specific application scenarios. 316L is suitable for fields with extremely high hygiene requirements, such as medical equipment and food processing. 304 is widely used in daily scenarios such as kitchen equipment and decoration. Its high strength, high toughness and easy cleaning and maintenance make it the preferred material for many high-end projects and special industries.

Aluzinc Steel: Both belong to zinc-aluminum-silicon alloy coated steel and have similar excellent corrosion resistance. After 2,500 hours of neutral salt spray test, its corrosion resistance performance is still more than 2.5 times better than that of ordinary galvanized steel plates. Its excellent processing performance enables it to adapt to various processing techniques such as stamping, bending and rolling, and can be easily applied in fields like building exterior walls, roofs, industrial equipment shells and agricultural greenhouse frames. While ensuring long-term protection, it provides an economical material option for projects, making it an ideal choice for balancing performance and cost.

Prepainted Steel: By pre-applying organic coatings on the surface of steel plates, it achieves rich color and texture effects, meeting the personalized design requirements of architectural and industrial products. We have introduced the world-leading eight-coat and eight-bake continuous production line and used an AI visual inspection system to monitor the coating thickness and uniformity in real time, ensuring that the color accuracy error of each sheet is less than 0.5ΔE. Special coatings such as polar anti-cold and desert anti-ultraviolet have been developed for different climate zones and application environments. They have been certified by the American AAMA 2605 standard and can withstand extreme temperature differences ranging from -60 ℃ to 100℃. The products are widely used in the decoration and renovation of industrial plants, commercial buildings, and civil residences, as well as in the manufacturing of home appliances and furniture, etc. They ingeniously integrate practical functions with aesthetic design, adding unique charm to the projects.
