Since 2025, driven by policies on green low-carbon development and intelligent manufacturing, key metal materials including Galvanized Steel, Galvalume Steel/Aluzinc Steel, Prepainted Steel, Stainless Steel, and Aluminum Coil/Pipe/Plate have entered a period of technological breakthroughs. Through optimizing material formulas and integrating cross-industry technologies, domestic enterprises have promoted performance upgrades of multi-category materials, injecting impetus for high-quality development into sectors such as infrastructure, logistics, and manufacturing.​ Coated Materials "Compete for Excellence": Dual Breakthroughs in Corrosion Resistance and Environmental Protection​As fundamental materials in industrial and construction fields, the technological upgrading of Galvanized Steel and Galvalume Steel has become an industry focus. Traditional Hot-dip Galvanized Steel achieves basic corrosion protection in ordinary atmospheric environments relying on the electrochemical protection properties of zinc coating, but its service life is limited in extreme environments such as coastal high-salt spray and industrial acid rain. Against this backdrop, Galvalume Steel (also known as Aluzinc Steel) with 55% Al-Zn alloy coating stands out due to its dual advantages of "aluminum's physical barrier + zinc's cathodic protection". Its corrosion resistance is 2-6 times that of ordinary Galvanized Steel, maintaining stability at high temperatures of 315℃ for a long time, with a thermal reflectivity of over 75%.​ The practice of Jinsteel Holding Group, a leading domestic enterprise, is representative. The high-end Zn-Al-Mg prepainted steel sheets developed by the company in collaboration with AkzoNobel use 150g/㎡ Zn-Al-Mg-coated steel as the base material, combined with 7+20μm PVDF coating. Passing the 1000-hour UV-B aging test, their service life is extended to 50 years, 4 times that of traditional prepainted steel sheets. This composite technical route of "coating + film" not only retains the core advantages of Galvalume Steel in heat resistance and corrosion protection but also enhances self-cleaning and UV resistance through PVDF fluorocarbon coating. It has been successfully applied to the plant enclosure system of Yudong Zijin Intelligent Logistics Industrial Park, meeting the high-standard scenario requirements of digital warehousing and intelligent logistics.​ Prepainted Steel and Aluminum Materials: Lightweight Features Adapt to Green Building Needs​The environmental upgrading of Prepainted Steel has become another technical highlight. Addressing the pain points of high VOC emissions and easy fading of traditional products, industry leaders have adopted the innovative solution of "Zn-Al-Mg replacing traditional base material + solvent-free coating". The external wall system of Jinsteel Photovoltaic Equipment Industrial Park has realized this replacement, reducing the material corrosion rate to 1/5 of that of traditional prepainted steel sheets and cutting the whole-life-cycle maintenance cost by 60%. The cutting-edge coating technology provided by coating enterprises such as AkzoNobel enables Prepainted Steel to achieve "50-year color durability" in multi-climate areas like Shangqiu, meeting the dual needs of aesthetics and durability for intelligent industrial parks.​ Aluminum Coil/Pipe/Plate are seizing the high-end market by virtue of their lightweight advantages. In the construction field, aluminum alloy plates have become the preferred choice for curtain wall and roof systems due to their density being only 1/3 of that of steel. In industrial pipeline scenarios, the oxidation resistance of aluminum pipes adapts to corrosive environments such as chemical industry and water treatment. Meanwhile, high-precision aluminum coils have been applied in batches in fields such as home appliance panels and new energy battery casings, promoting the upgrading of end products towards "lightweight and long service life".​ Stainless Steel and Cross-Industry Integration: Building an Industrial Ecosystem Across Multiple Scenarios​Stainless Steel continues to deepen its presence in high-end manufacturing fields relying on its high strength and acid-alkali resistance. In scenarios such as food processing and medical equipment, stainless steel grades like 304 and 316L meet strict hygiene standards through surface polishing and antibacterial treatment. In the new energy field, stainless steel pipes have become core components of hydrogen storage systems for hydrogen fuel cells, and their hydrogen embrittlement resistance provides support for the industrialization of hydrogen energy.​ Notably, material enterprises are building industrial ecosystems through cross-industry cooperation. The "base material + coating" joint R&D model between Jinsteel and AkzoNobel, and the standardization practice of Baosteel in the field of hot-dip Galvalume steel plates, have promoted the transformation of metal materials from "single product supply" to "systematic solutions". Data shows that in 2025, the domestic market share of Galvalume Steel has increased by 12 percentage points compared with three years ago, and the penetration rate of Zn-Al-Mg prepainted steel sheets in the logistics infrastructure field has exceeded 20%.​ Industry experts point out that with the in-depth implementation of the "Green and Low-Carbon Development Roadmap for China's Iron and Steel Industry", the upgrading of materials such as Galvanized Steel and Galvalume Steel will focus on the three directions of "reduced coating weight, solvent-free coating, and recycling". Meanwhile, the application scenarios of aluminum materials and Stainless Steel will further extend to strategic fields such as new energy and high-end equipment, providing core support for the green transformation of Made in China.​

It is predicted that the domestic aluminum industry market scale will exceed 2.5 trillion yuan in 2025, and steel consumption is expected to rebound to 1.01 billion tons.​ Dual Breakthroughs in Superconductivity and Corrosion Resistance: Prepainted Steel Opens New Track​Jinguang Holdings Group recently realized the mass production of China's first superconducting prepainted steel sheets. This innovative product, based on a zinc-aluminum-magnesium substrate, adopts special superconducting paint coating and an original coupling agent formula, controlling the conductive resistance within 50 milliohms. Meanwhile, relying on the high-content coating ratio of 3% magnesium and 6% aluminum, it achieves self-repair of cut sections, with corrosion resistance far exceeding that of conventional products. The neutral salt spray test shows no corrosion for 4,000 hours, and its service life can reach 30 years, doubling that of traditional prepainted steel sheets.​ "Precise control is implemented from the steelmaking process, with the cleanliness of molten steel and alloy ratio controllable throughout," introduced Zou Ming, Chief Technology Officer of Jinguang. Relying on a cold rolling plant with independent intellectual property rights covering the entire process, the enterprise has formed six high-quality product series including galvanized steel, galvalume steel, and prepainted steel. The rolling speed of 1,500 meters per minute and color difference control accuracy within 0.5 on the production line have reached international leading levels.​ Stainless Steel Prepainted Sheets Solve the Industry Dilemma of "Welding Corrosion"​The "Zebra" stainless steel prepainted sheets launched by Baosteel Co., Ltd. adopt the "designated area customized coating" technology, accurately reserving welding areas on the steel sheet surface to realize the staggered distribution of bare steel and coating, which completely solves the pain point of coating damage caused by traditional prepainted sheet welding. This product uses high-performance stainless steel substrate and modified fluorocarbon topcoat, with the neutral salt spray corrosion resistance test exceeding 70,000 hours, nearly quadrupling that of conventional products. It is especially suitable for high-end building roofs in coastal high-humidity and high-salt environments.​ To achieve extreme precision, the Baosteel team optimized the roll coating system and coating process, controlling the stripe boundary deviation of 3,000-meter-long sheets at the micrometer level. At the same time, it eliminated the "thick edge" defect of the coating, ensuring the leveling property and gloss uniformity of the paint film, with an appearance flatness comparable to that of a mirror.​ Full-Industry-Chain Upgrading Supports Material Innovation​The breakthrough of high-end metal materials cannot be separated from the dual empowerment of equipment and systems. Jinguang has built an intelligent production system covering the entire industry chain. The pickling and cold rolling unit adopts advanced technologies such as laser welding and shallow tank turbulent pickling, and the continuous hot-dip coating unit can flexibly produce galvanized steel, zinc-aluminum-magnesium steel, galvalume steel and other multi-category products. Combined with intelligent logistics and AI quality control system, it realizes minimal human intervention in the whole production process. At present, the enterprise has obtained multiple international certifications including EU CE, American standards and European standards, maintaining a R&D investment speed of "one patent per week" and accumulating more than 100 national patents.​ At the policy level, the state exerts dual efforts through production capacity regulation and R&D support. While controlling electrolytic aluminum production capacity within 45 million tons, the central fiscal special fund supports the R&D of key technologies such as high-end aluminum alloys and corrosion-resistant steel, promoting the proportion of high-end aluminum materials output to increase to 28% and high-end steel output to exceed 180 million tons in 2024. In the field of green transformation, enterprises such as Baosteel and Angang have accelerated the layout of electric arc furnace steelmaking. In 2024, the output of electric arc furnace steel increased by 6.3% year-on-year, while Jinguang realized the low-carbonization of the production process through comprehensive recycling of waste energy.​ Global Market Competitiveness Continues to Strengthen​Technological upgrading is promoting the optimization of the export structure of China's metal materials. In 2024, the domestic export volume of aluminum materials reached 5.8 million tons, with a year-on-year increase of 7.2%, and the export average price rose by 3.1%; the export volume of steel products reached 72 million tons, among which the proportion of high-end plates continued to increase. It is expected that the export volumes of the two categories will increase to 6.1 million tons and 75 million tons respectively in 2025. From lightweight aluminum materials for new energy vehicles to corrosion-resistant steel materials for high-end buildings, China's metal materials are occupying higher value links in the global industrial chain by virtue of the advantages of "performance upgrading + cost control".​ Industry experts point out that with the large-scale application of technologies such as superconductivity and long-term corrosion resistance, traditional categories including galvanized steel, stainless steel and aluminum materials will be revitalized. The full-industry-chain advantages and continuous innovation capabilities of leading enterprises will accelerate China's transformation from a major metal material producer to a powerful one.​

As the global construction, appliance, and new energy industries recover and transform, the metal materials market is showing a trend towards diversification and high performance.
