Focus on the cutting-edge of metal materials: Multi-category products usher in a new era of industry

In the current context where the global industrial landscape is accelerating its reshaping, high-performance metal materials are becoming the core force driving industrial upgrading and innovative development. A series of metal products such as Aluminum Coil/Pipe/Plate, Galvanized Steel, Prepainted Steel, Galvalume Steel, Stainless Steel and Aluzinc Steel With its outstanding performance and diverse characteristics, it is deeply integrated into every link of modern industry, laying a solid foundation for the development of global manufacturing.

Aluminum Products occupy an important position in many industries due to their excellent lightweight characteristics. In the aerospace field, aluminum alloy, with a density only one-third that of steel and excellent specific strength, has helped the Boeing 787 passenger aircraft achieve a 20% reduction in fuselage weight and a significant 15% increase in fuel efficiency. In the construction industry, aluminum coils that have undergone anodizing treatment can present over 200 brilliant colors, not only adding unique aesthetic value to the facade of the Centre Pompidou in Paris, but also significantly reducing the building's operation and maintenance costs with their maintenance-free corrosion resistance for up to 50 years. In the automotive industry, the wide application of aluminium components has increased the average driving range of new energy vehicles by 8% to 12%. Take 6-series aluminum alloy as an example. Through T6 heat treatment and pre-stretching process, its yield strength can reach 276MPa, demonstrating unparalleled advantages in precision manufacturing fields such as 3C product shells and battery trays for new energy vehicles.

Galvanized steel, relying on its century-old accumulated anti-corrosion technology, continues to thrive in the industrial field. The hot-dip galvanizing process builds a dense zinc-iron alloy layer of 80-120μm on the surface of steel through a high-temperature molten plating process at 550℃, ensuring that the steel structure of the Lusail Stadium, the main stadium of the Qatar World Cup, can maintain an anti-corrosion life of more than 50 years under tropical Marine climate conditions. Compared with hot-dip galvanizing, cold galvanizing can reduce costs by 30%, but its zinc coating thickness is only 10-15μm, and it has been explicitly prohibited from being used in drinking water delivery systems. The recently developed double-layer galvanizing technology, through a composite process of "hot-dip galvanizing + electro-galvanizing", has enabled the salt spray resistance test time of steel to exceed 3,000 hours, setting a new industry standard.

Color-coated steel is redefining industrial aesthetics with an innovative model of "color + function". The fluorocarbon color-coated steel sheet developed by Baosteel Co., Ltd. undergoes seven coating processes and is cured at a high temperature of 250℃. The coating hardness reaches 2H level and has an anti-ultraviolet aging ability of up to 30 years. It is widely used in the silver corrugated roof of Tesla's Gigafactory. In the field of home appliances, the advent of nano-self-cleaning coated color-coated steel plates has reduced the amount of dirt adhering to the refrigerator shell by 70% and extended the maintenance cycle to five times the original. Data shows that the global color-coated steel market size exceeded 18 million tons in 2023, with an average annual growth rate of 6.8%.

Aluminized zinc steel, with its golden composition ratio of "55% aluminum - 43.4% zinc - 1.6% silicon", has opened up a brand-new chapter in metal protection. The unique "diamond flower" crystal form on its surface not only endows the material with a distinctive metallic luster but also achieves self-repairing functions through the micro-battery effect. In extreme environmental tests, the corrosion resistance of aluminized zinc steel is 4 to 6 times that of ordinary galvanized steel. In the acid rain environment of Southeast Asia, the service life of the roof can reach 40 years. In recent years, home appliance enterprises have applied it to the outdoor unit protection nets of air conditioners, extending the outdoor warranty period of the products from 8 years to 15 years.

Stainless steel is constantly expanding its application territory with its "all-scenario adaptability". Food-grade 304 stainless steel, with a carbon content of ≤0.08% and a chromium content of ≥18%, ensures the aseptic production of dairy product lines. Medical-grade 316L stainless steel, by adding 2-3% molybdenum, has a 90% improvement in biocompatibility and is widely used in medical devices such as cardiac stents and orthopedic implants. In the field of architecture, etched stainless steel, with the aid of nanoimprint technology, has created a silky texture for the curtain wall system of the Shanghai Tower, while also featuring anti-fingerprint and easy-to-clean properties.

Aluminum-zinc steel has emerged in the market as an "all-round player". The dense aluminum-zinc alloy layer of 0.2-0.3mm on its surface enables the material to maintain 95% of its mechanical properties even in a high-temperature environment of 315℃. In the application of photovoltaic module frames, its salt spray resistance exceeds the IEC standard by twice. Its unique surface conductivity (resistivity ≤1.5Ω · cm) makes it an ideal choice for battery pack protection boards in new energy vehicles, which can not only effectively shield electromagnetic interference but also reduce the risk of short circuits.

Facing the advancement of the global carbon neutrality goal and the development wave of intelligent manufacturing, the metal materials industry is accelerating technological innovation and iteration. The world's leading enterprises invest an average of 4.2% of their annual revenue in research and development, continuously driving breakthroughs in product performance through cutting-edge technologies such as nano-coatings and 3D printing adaptation materials. With the deep integration of Industry 4.0 and the concept of green manufacturing, Metal products such as Aluminum Coil/Pipe/Plate, Galvanized Steel, Prepainted Steel, Galvalume Steel, Stainless Steel and Aluzinc Steel It will surely inject strong impetus into the progress of global industrial civilization in a more environmentally friendly, intelligent and efficient manner.
