In the contemporary industrial landscape, 45g alu zinc coils (commonly known as Galvalume or Aluzinc) have emerged as the gold standard for projects requiring an optimal balance between cost-efficiency and long-term durability. With a coating composition of 55% aluminum, 43.4% zinc, and 1.6% silicon, the 45g/m² coating weight is specifically engineered for environments that demand superior heat reflectivity and atmospheric corrosion resistance.
Global demand is surging in regions like Southeast Asia, the Middle East, and Latin America, where rapid urbanization and infrastructure expansion are driving the need for reliable roofing and cladding materials. The 45g specification is particularly favored in the solar energy sector for mounting structures, where lightweight yet robust materials are essential for massive PV installations.
Leading the Way in Steel Material Supply and Manufacture since 2010.

Our production facilities cover over 66,700 square meters factory, featuring eight High Frequency welded lines. Each line has a complete set of equipment to accomplish at least five production steps, ensuring a monthly output of 100,000 tons, half of which is exported globally.
Our facilities include a molding workshop complete with 20 R&D engineers possessing over 10 years’ experience. We specialize in value for clients, providing tailored solutions for pre-galvanized, hot-dip, and alu-zinc requirements.
STEP MILLION STEEL SUPPLY CHINA CO., LTD. has established stable strategic cooperation with world-renowned enterprises such as LG Electronics and Xizi United. Our markets cover nearly 100 countries across Middle & South America, Southeast Asia, the Middle East, and Africa.
As global carbon neutrality targets approach, the construction industry is shifting towards 100% recyclable materials. Alu-zinc coils, with their long lifespan and recyclability, are becoming the preferred choice for green-certified buildings.
The global transition to renewable energy has created a massive procurement need for 45g alu zinc coils. These coils provide the necessary structural integrity and corrosion resistance for solar farm brackets in harsh outdoor environments.
Smart manufacturing and AI-driven quality control are now industry standards. As a modern factory, we utilize German and Japanese testing equipment to ensure every micron of the 45g coating is uniform and compliant with international standards.
From residential roofs to heavy industrial machinery, 45g alu zinc coils serve diverse sectors.
Widely used for purlins, floor decks, and structural frames in commercial buildings due to high strength-to-weight ratios.
Ideal for residential and industrial roofing, providing excellent thermal insulation and resistance to acid rain.
The anti-fingerprint variant of alu-zinc is perfect for washing machines, refrigerators, and oven back panels.
Used in non-visible structural parts and exhaust system components where heat resistance is paramount.
Essential for manufacturing outdoor cabinets, ventilation ducts, and precision metal stamping parts.
