In the fields of architectural decoration and industrial manufacturing, the demand for the functionality and visual expressiveness of materials continues to rise. Color Galvanized and coated Steel sheets, with their innovative technology and outstanding performance, have become the ideal choice with both practical and aesthetic value. Together with products such as Galvalume Steel and Galvanized Steel, they form a complete matrix of metal material solutions to meet diverse engineering needs.

Galvalume Steel: The pinnacle of Alloy technology
By using a precise ratio of 55% aluminum, 43.4% zinc and 1.6% silicon, and through vacuum hot-dip galvanizing nanotechnology, an atomic-level honeycomb alloy coating is formed on the surface of the steel plate. Tested by ISO 9227 standard salt spray, its corrosion resistance is 4 to 6 times that of Galvanized Steel, and it can serve stably for a long time in a high temperature environment of 380 ° C. With a thermal reflectivity of up to 75%, it effectively reduces building energy consumption. The mirror-like surface (Ra≤0.3μm) enhances the adhesion of the coating by 60%. It is widely applied in super high-rise curtain walls, new energy vehicle chassis and high-end home appliance manufacturing, redefining the standard of metal protection with its extremely long service life and ultimate processing performance.

Galvanized Steel: A Modern interpretation of classic craftsmanship
By applying the AI dynamic temperature control hot-dip galvanizing technology, the temperature fluctuation of the zinc liquid is precisely controlled within ±0.5℃, forming a dense Zn-Fe alloy layer of 8-25 μm. Tested in accordance with the GB/T 13912 standard, the adhesion of the zinc coating reaches the highest grade, and the cold bending performance meets the B-level standard (no cracks at 180° bending). The mature process system ensures zero deviation in the performance of batch products. With excellent weldability and formability, it has become the basic protective cornerstone for building steel structures, industrial pipeline systems and precision hardware manufacturing. Its zinc layer sacrificial anode protection mechanism can continuously safeguard the steel substrate even if the surface is damaged. With stable and reliable performance and high cost-effectiveness, it supports the construction of millions of projects.

Aluminum Coil/Pipe/Plate: Lightweight and high-strength future materials
Aviation-grade 7075-T651 and 6061-T6 aluminum alloys are selected. Through three-directional forging and two-stage aging process, an ultra-high strength of 620MPa and an ultimate lightweight of 2.7g/cm³ are achieved, effectively reducing the structural self-weight by 55%. The surface micro-arc plasma oxidation technology forms a 40μm ceramicized oxide film, with a salt spray resistance time exceeding 2200 hours and a thermal conductivity of 190W/(m · K). From high-speed maglev tracks to new energy battery boxes, from deep-sea exploration equipment to food-grade packaging materials, with outstanding corrosion resistance, electrical conductivity and 100% recyclability, it leads the green manufacturing revolution.

Stainless Steel: The quality benchmark in the high-end field
The AOD-VOD double vacuum refining + electroslag remelting process was adopted to precisely control the carbon content below 0.008%, ensuring the atomically dense passivation film. The series of products such as 304L, 316Ti and 904L have passed the highest-level certification of EN 10088-3. 316L complies with the ISO 10993 Class VI biocompatibility standard and has become the first choice for medical equipment and food processing. 904L demonstrates outstanding resistance to Cl⁻ corrosion in the fields of Marine engineering and chemical engineering. The 201 stainless steel with nano mirror finish (Ra≤0.05μm) infuses the commercial space with ultimate aesthetics, setting a quality benchmark in the industry with its all-round outstanding performance.

Aluzinc Steel: The golden ratio of performance to cost
Inheriting the core technology of Galvalume Steel, the best balance between performance and cost is achieved through process optimization. A 3,000-hour neutral salt spray test shows that its corrosion resistance is three times better than that of Galvanized Steel and it can withstand a high temperature of 315 ° C. Its excellent cold-bending formability (elongation ≥32%) makes it widely used in container manufacturing, agricultural greenhouses, outdoor billboards and other fields. Offering superior protection over traditional Galvanized products at a cost close to Galvanized Steel, it is the ideal choice for small and medium-sized projects.

Prepainted Steel: The perfect unity of color and function
We have introduced a German intelligent eight-coat and eight-bake production line, and the AI vision closed-loop control system enables precise control of the coating thickness within ±0.3μm. Coatings such as PVDF fluorocarbon and HDP high-weather-resistant polyester have passed the highest-level AAMA 2605 certification. The outdoor weather-resistant life reaches 35 years, and the color retention ΔE is ≤0.6. Supporting Pantone full-color customization and 3D texture printing, from the functional exterior walls of industrial plants to the artistic skin of commercial complexes, from the fashionable design of home appliance shells to the personalized expression of furniture panels, with rich color language and outstanding weather resistance, it endows buildings and products with unique charm.
