Stainless Steel

Galvalume Steel redefines the standard of metal protection with revolutionary alloy coating technology. The 55% aluminum-45% zinc alloy coating formed through the hot-dip galvanizing process achieves a tight metallurgical grade bond, establishing a dual defense system of physical protection and electrochemical protection. Its corrosion resistance is four times that of ordinary galvanized steel. It can stably withstand over 1,500 hours in salt spray tests. Even when subjected to 90° extreme bending, the coating remains intact. With excellent formability and coating compatibility, this material is widely used in the photovoltaic industry, enhancing the weather resistance of the support system by 30%. In the field of home appliance manufacturing, it provides long-lasting protection for products such as ovens and washing machines for up to 25 years. In the application of building roofs, it effectively resists the erosion of industrial atmosphere and ensures the long-term stable operation of buildings.

Galvanized Steel, a leading force in industrial protection, forms a dense zinc coating on steel surfaces through hot-dip or electroplating processes. By precisely controlling the coating thickness of 80-600g/㎡, a long-lasting anti-corrosion period of 5 to 50 years can be provided. With a cost advantage of only one-third that of stainless steel, it can meet the demands of 80% of conventional anti-corrosion scenarios, thus occupying an important position in the market. From the steel structure frames of skyscrapers to the guardrails and street lamp poles of urban infrastructure, and even to the chassis components of automotive manufacturing, galvanized steel plates are everywhere. When used in conjunction with Prepainted Steel color-coated steel sheets, it can create a perfect combination of "anti-corrosion at the bottom layer + surface decoration", endowing outdoor facilities with both outstanding protective performance and a fashionable appearance.

Aluminum Coil/Pipe/Plate leads the trend of material innovation with the perfect integration of extreme lightweight and high performance. Based on high-end alloy systems such as 6061 and 7075, through advanced rolling and extrusion processes, a variety of product forms are shaped. 0.01mm food-grade aluminum foil, with its outstanding barrier performance, provides safe and reliable moisture-proof and fresh-keeping protection for medicines and food. The 1-3mm aluminum coil for construction, after being treated with fluorocarbon roller coating, not only meets the high standard of AAMA 2605, but also adorns the brilliant appearance of global landmark buildings such as the Burj Khalifa in Dubai with brilliant colors and long-lasting weather resistance. The internal threaded aluminum tubes in the aluminum tubes, by optimizing the heat exchange structure, increase the heat exchange efficiency of the air conditioning system by 20%. Aviation-grade seamless aluminum tubes, with their high strength and lightweight characteristics, can withstand high-pressure fuel transportation at 30MPa, providing crucial support for the aerospace industry. After the 5 series aluminum plates are formed through hot stamping, the vehicle body weight is reduced by 30% while the strength is increased by 40%, contributing to the performance breakthrough of new energy vehicles. The 7-series aluminum plate, with its excellent mechanical properties, has become the preferred material for core components such as wing ribs of the C919 passenger aircraft.

Stainless Steel, with its precise alloy formula and outstanding performance, has become the ultimate solution under extreme conditions. Based on iron-based alloys with a chromium content of ≥10.5%, by precisely regulating the proportions of elements such as nickel, molybdenum and titanium, a series of products with various functions have been derived. Type 304 stainless steel, with its classic composition of 18Cr-8Ni, has good versatility and food-grade safety, and is widely used in kitchenware, medical devices and other fields. 316L type stainless steel, due to the addition of 2.5% molybdenum and the adoption of a low-carbon design, has excellent resistance to chloride ion corrosion and can operate stably in harsh environments such as seawater desalination and pharmaceutical purified water systems. The 310S type stainless steel, with its high alloy content of 25Cr-20Ni, can maintain excellent oxidation resistance and mechanical properties in a high-temperature environment of 1200℃, making it an ideal choice for heat treatment furnace tubes and nuclear power steam pipes. In addition, stainless steel has demonstrated strong capabilities in the field of precision processing. The wall thickness tolerance of seamless pipes can be controlled within ±0.05mm, and the thickness of ultra-thin steel strips can reach 0.05mm, which can meet the application requirements of all scenarios from deep freezing at -253 ℃ to high temperatures at 1150℃.

Aluzinc Steel is specifically designed for extreme environmental challenges. Its unique gradient alloy coating (with an aluminum content of 5-15%) effectively resists harsh conditions such as high salt spray, high acid and alkali, and high humidity through innovative processes. Strictly certified by the GB/T 14978 standard, in the construction of coastal wind power towers, its service life is 1.5 times longer than that of ordinary galvanized steel. It can effectively resist sulfide erosion in highly corrosive environments such as waste incineration plants. The dual protection mechanism of "aluminum-based physical barrier + zinc-based electrochemical protection" enables it to remain stable in acidic and alkaline environments with pH ranging from 3 to 11, providing reliable long-term protection for key facilities in fields such as chemical engineering and Marine engineering.
