Precision Cold Rolled Stainless Steel Coils

As the core basic materials of industrial manufacturing, our 304 and 430 cold-rolled stainless steel coils, with their outstanding precision performance and reliable quality, have become the first choice for high-end equipment manufacturing. 304 stainless steel coil adopts the classic ratio of 18% chromium -8% nickel, featuring excellent formability, weldability and corrosion resistance. It is particularly suitable for sanitary application scenarios such as food machinery, medical equipment and chemical containers. The 430 stainless steel coil features an optimized composition of 16% chromium, offering excellent corrosion resistance while providing a superior cost-performance ratio. It is an ideal choice for home appliance panels, automotive decoration, and architectural hardware fields. Through advanced cold rolling process and bright annealing technology, our products can achieve hardness control of different grades from H-H to S-S. The surface finish can reach multiple standards such as BA/2B/NO.4, and the thickness tolerance is precisely controlled within ±0.02mm. Whether it is precision components that require deep stamping or decorative materials that pursue a mirror-like effect, 304 and 430 cold-rolled stainless steel coils can provide perfect material solutions to help customers create more competitive end products.

Galvalume Steel: As an innovative work in the field of metal building materials, Galvalume steel plates, through the unique 55% aluminum-zinc alloy coating technology, perfectly combine the excellent corrosion resistance of aluminum with the high strength characteristics of steel. Its revolutionary metal coating structure can provide anti-corrosion protection up to 2 to 4 times that of traditional galvanized steel plates, making it particularly suitable for harsh Marine climates and industrial environments. In addition to its outstanding weather resistance, Galvalume has a solar reflectivity of up to 80%, which can significantly reduce building energy consumption. From modern factory roofs to high-end building curtain walls and even agricultural storage facilities, Galvalume steel plates are redefining the value standards of building envelope systems with their extremely long service life and excellent formability.

Galvanized Steel: Hot-dip galvanized steel sheet, which has been refined through over a hundred years of craftsmanship, remains the gold standard in industrial anti-corrosion to this day. Through a rigorous zinc bath plating process, a dense zinc-iron alloy layer is formed on the surface of the steel, endowing it with extraordinary sacrificial anode protection capability. This "self-healing" property ensures that even in the event of mechanical damage, the coating can still continuously provide cathodic protection. In major infrastructure projects such as bridge steel structures, highway guardrails, and transmission and transformation towers, galvanized steel plates, with their long-lasting durability, quietly safeguard the safe operation of modern cities. The newly developed differential thickness galvanizing technology can achieve single-sided differentiated anti-corrosion, providing precise protection solutions for special applications such as automotive plates.

Aluminum Coil/Pipe/Plate: Aluminum alloy materials, with their unique lightweight advantages, are reshaping the modern industrial manufacturing pattern. Our aluminum coil, aluminum tube and aluminum plate products are produced by international advanced continuous casting and continuous rolling technology, featuring aerospace-grade dimensional accuracy and mechanical properties. Thanks to the natural oxide protective film, aluminium materials can still maintain excellent stability in harsh environments such as moisture, acids and alkalis. What is more worth mentioning is that the 100% recyclable feature of aluminium makes it the preferred material for green buildings. From battery trays for new energy vehicles to lightweight components in subway carriages, from photovoltaic bracket systems to medical gas pipelines, aluminum materials are driving industrial upgrading with their outstanding cost performance.

Stainless Steel: As the "noble" of industrial materials, stainless steel has conquered countless demanding application scenarios with its inherent noble texture and outstanding performance. The series of stainless steel products we offer, such as 304/316L, adopt vacuum refining technology to ensure ultra-low carbon content, significantly enhancing welding performance and resistance to intergranular corrosion. In the field of food and pharmaceuticals, stainless steel equipment meets GMP-level hygiene standards. In coastal buildings, molybdenum-strengthened stainless steel can resist salt spray erosion. In the high-end home appliance sector, precisely embossed stainless steel panels have become a symbol of a quality life. With the advancement of surface treatment technology, from mirror polishing to antibacterial coatings, stainless steel is constantly expanding its application boundaries.

Aluzinc Steel: This breakthrough aluminum-zinc-silicon alloy coated steel plate represents the latest breakthrough in metal anti-corrosion technology. Its unique microstructure contains 80% aluminum phase and 20% zinc phase. In terms of anti-corrosion mechanism, it has the dual advantages of barrier protection of aluminum and cathodic protection of zinc simultaneously. Measured data shows that under the same coating thickness, the corrosion resistance life of Aluzinc is more than six times that of traditional galvanized sheets. What is even more astonishing is its outstanding heat resistance, which can withstand a high temperature of 300℃ for a long time without failure. This makes it an ideal choice for industrial plant color steel tiles and automotive exhaust systems. The innovative coating technology can also achieve a variety of color customization, meeting the architectural aesthetic requirements.

Prepainted Steel: Pre-coated steel plates have pushed the traditional coating process to a new height of intelligent manufacturing. Our products adopt the internationally leading roller coating technology to achieve multi-layer precise coating of primer, topcoat and protective film on high-speed continuous production lines. This industrialized coating method not only ensures uniform and controllable film thickness, but also achieves a surface accuracy of 5μm that is difficult to reach with traditional spraying. The specially developed PVDF fluorocarbon coating has extremely strong weather resistance, and the color retention period can reach more than 20 years. From the exterior walls of prefabricated buildings to the panels of smart home appliances, from cleanroom partitions to artistic decorative components, pre-coated steel plates are redefining the infinite possibilities of metal surfaces with technology.
