The wave of metal material manufacturing
Against the backdrop of the global manufacturing industry's accelerated transformation towards high-end, intelligent and green development, metal materials, as the cornerstone of modern industry, are undergoing profound changes and innovative development. Key categories such as aluminized zinc steel sheets, Galvanized Steel sheets, aluminum coils/tubes/plates, Stainless Steel, aluminized zinc magnesium steel sheets, and color-coated steel sheets have become the core driving force for the high-quality development of various industries, thanks to breakthroughs in cutting-edge technologies and the expansion of application fields.
Aluminized zinc steel sheet: Technological innovation expands the application scope
A major technological leap has been achieved in the field of aluminized zinc steel sheets. By optimizing the alloy composition and coating process, the comprehensive performance of the products has been significantly improved. The new generation of aluminized zinc steel plate developed by Wuhan Iron and Steel Corporation adopts a zinc-aluminum-rare earth alloy coating. Its corrosion resistance in harsh industrial environments has been improved by 70%, far exceeding that of traditional products. Its surface is treated with special passivation, which significantly enhances the adhesion and weather resistance of the coating. In the application of outdoor photovoltaic power station brackets, its service life is extended to over 30 years, effectively reducing the total life cycle cost by 40%. Meanwhile, this product, with its excellent formability and electrical conductivity, has been widely applied in the manufacturing of battery trays for new energy vehicles, contributing to the development of the automotive industry towards lightweight and safety.
Galvanized Steel Sheet: Green intelligent manufacturing leads industrial transformation
The galvanized steel sheet industry actively practices the concept of green development and accelerates the process of intelligent production. Shougang has introduced an intelligent zinc pot control system, which precisely regulates the temperature, flow rate and galvanizing time of the zinc liquid by using big data and AI algorithms, achieving a 20% reduction in zinc consumption and a 35% increase in production efficiency. The new type of galvanized steel plate adopts an environmentally friendly chromium-free passivation process, reducing heavy metal pollution from the source and meeting the EU RoHS standard. In the field of construction, high-strength galvanized steel sheets are used in the structural components of prefabricated buildings. Their excellent anti-rust and mechanical properties ensure a service life of over 50 years for building structures. At the same time, they simplify the construction process and promote the construction industry to move towards a green and efficient direction. In the home appliance industry, the wide application of galvanized steel plates has enhanced the durability and aesthetic appeal of products, meeting consumers' demands for high-quality home appliances.
Aluminum coils/tubes/plates: Lightweight innovation empowers development in multiple fields
Aluminum materials have shone brightly in fields such as aerospace, new energy vehicles, and architectural decoration due to their outstanding properties of lightweight, high specific strength, and corrosion resistance. The ultra-high strength aluminum alloy plates developed by AVIC Aluminum Industry have achieved a strength of over 700MPa through advanced hot working and aging treatment processes. They have been successfully applied to key parts of the wings and fuselage of domestically produced large aircraft, reducing the structural weight of the aircraft by 15% and effectively enhancing fuel efficiency and flight performance. In the field of new energy vehicles, BYD adopts an integrated die-cast aluminum body technology, extensively using aluminum profiles and plates. As a result, the overall vehicle weight is reduced by 12%, and the driving range is increased by 10% to 15%. Meanwhile, the demand for aluminum coils in the architectural decoration industry continues to rise. Through technologies such as pre-roller coating and transfer printing, aluminum coils can present a rich variety of colors and textures, meeting the needs of personalized and high-end architectural design, and adding a beautiful landscape to urban buildings.
Stainless steel: High-end customization to meet special needs
The stainless steel industry focuses on the research and development of high-end products and customized services to meet the strict demands of various industries. The super austenitic stainless steel developed by Taiyuan Iron & Steel (Group) Co., Ltd. can maintain excellent mechanical properties and corrosion resistance even in high-temperature, high-pressure and highly corrosive chemical environments. It has been successfully applied to key equipment such as large-scale refining and chemical plants and nuclear power evaporators. For the food and medical industries, the enterprise has launched sanitor-grade stainless steel, which has undergone special electrolytic polishing and passivation treatment. The surface roughness Ra is ≤0.1μm, and the bacterial adhesion rate is reduced by more than 90%, meeting international hygiene standards such as the US FDA and the EU EN10088. Customized services have become a new highlight in the stainless steel market. Enterprises provide products with special specifications, performance and surface treatment based on customer demands, such as customizing antibacterial stainless steel for high-end kitchenware and seawater corrosion-resistant stainless steel for Marine scientific research equipment, further expanding the application boundaries of the market.
Aluminized zinc-magnesium steel sheet: A new type of material is emerging
Aluminized zinc-magnesium steel sheet, as a new generation of high-performance metal material, has rapidly captured the market with its excellent performance. The aluminized zinc-magnesium steel plates produced by Shagang adopt a unique zinc-aluminum-magnesium-calcium alloy coating formula. Under the same coating thickness, their corrosion resistance is 6 to 8 times that of ordinary galvanized steel plates. In scenarios such as highway guardrails and outdoor billboards that are constantly exposed to harsh environments, aluminized zinc-magnesium steel plates are gradually replacing traditional materials due to their advantages of extremely long service life and low maintenance costs. Its self-healing property enables zinc, aluminum and magnesium elements to react rapidly in the air even if the surface coating is partially damaged, forming a dense protective film that prevents the spread of corrosion and ensures the long-term stable use of the material.
Color-coated steel plate: Upgraded integration of functionality and aesthetics
The color-coated steel plate industry is accelerating its upgrade towards functionalization and aesthetics. The multi-functional color-coated steel plate jointly developed by Nippon Paint and Baosteel integrates multiple functions such as antibacterial, anti-fouling, heat insulation and flame retardancy, and is widely used in places with strict environmental requirements such as hospitals, schools and cold chain logistics. In terms of antibacterial performance, the antibacterial rate against common bacteria such as Escherichia coli and Staphylococcus aureus is as high as 99.9%. In terms of anti-stain performance, the special fluorocarbon coating makes it difficult for surface stains to adhere and makes it easy to clean and maintain. In terms of color and texture design, with the aid of cutting-edge technologies such as digital printing and 3D simulation, color-coated steel plates can realistically present effects like wood grain, stone grain, and fabric grain, meeting the pursuit of personalization and artistry in high-end architectural decoration. Meanwhile, the product has excellent weather resistance. Under extreme weather conditions, the coating will not fade or powderize for 10 years, providing long-lasting protection for the appearance of buildings.
