Coating technology and high-end alloys lead the development of the industry
Driven by the continuous growth of global infrastructure investment and the upgrading of manufacturing, the metal materials industry is undergoing a profound technological transformation. Traditional products such as Galvalume Steel, Galvanized Steel, and Aluminum Coil/Pipe/Plate have continuously optimized their processes. High-end materials such as Stainless Steel, Aluzinc Steel and Prepainted Steel are becoming the new favorites in the fields of construction, home appliances and new energy.
Aluminized zinc steel and galvanized steel: The demand in the construction field is growing steadily
Galvalume Steel, with its excellent corrosion resistance (2 to 4 times higher than that of ordinary galvanized steel) and heat resistance (able to withstand a high temperature of 600℃), dominates in the construction of industrial plants and warehousing facilities. Meanwhile, Galvanized Steel maintains a steady demand in the automotive sheet and home appliance sheet markets by improving zinc coating uniformity (using air knife control technology) and an environmentally friendly passivation process (chromium-free treatment). According to data from the International Zinc Institute, global consumption of galvanized steel exceeded 350 million tons in 2023, with China accounting for more than 45%.
The application fields of aluminium materials continue to expand
With the acceleration of the lightweight trend, the application of Aluminum Coil in the battery housings of new energy vehicles has soared, and the demand for mainstream thickness specifications of 0.3-3.0mm products has increased by 15% annually. The penetration rate of Aluminum Pipe in photovoltaic bracket systems has increased to 30%, and 6061-T6 alloy pipes have become the preferred choice due to their combination of strength and weather resistance. The technological breakthroughs of Aluminum Plate in the aerospace field are remarkable. The new type of aluminum-lithium alloy sheet reduces the weight by more than 10% compared with traditional materials.
Technological upgrades of stainless steel and aluminum-zinc-magnesium alloy steel
In the field of high-end applications, Stainless Steel is undergoing an upgrade of its product structure:
The consumption of 304/316L stainless steel in medical equipment and food machinery has increased by 8% annually
The application proportion of duplex stainless steel 2205 in Marine engineering has increased to 25%
The substitution rate of ultra-pure ferritic stainless steel 444 in the inner tank market of water heaters exceeds 60%
As a new generation of coating material, the cut protection ability of Aluzinc Steel's ternary alloy coating of aluminum-zinc-magnesium (55%Al+43.4%Zn+1.6%Mg) is five times higher than that of traditional aluminum-zinc coating, and it is rapidly penetrating the markets of automotive panels and photovoltaic frames.
Pre-coated color steel leads the revolution of architectural aesthetics
Prepainted Steel achieves performance breakthroughs through innovative coating technology:
The weather resistance of PVDF fluorocarbon coating is over 20 years
The application of antibacterial coated color steel plates in hospitals has increased by 30%
Self-cleaning nano-coating products were showcased at the European Building Materials Exhibition
Market Outlook
The latest report from CRU predicts that the global coated steel plate market size will reach 180 million tons in 2025, among which:
The Asia-Pacific region accounts for 58% (China accounts for 70%).
The demand in the construction field accounts for 45%
The growth rate of applications related to new energy has reached 12% per year
