In the global steel industry, the 275g GI sheet represents a heavy-duty benchmark for corrosion resistance. As a leading manufacturer, we provide 275g/m² zinc coating (total both sides) which ensures a service life often exceeding 20-30 years in outdoor environments. This specific weight—Z275—is the gold standard for projects demanding high durability without the excessive cost of stainless steel.
Currently, the demand for high-zinc galvanized sheets is surging across Europe, North America, and Southeast Asia. With the rise of Sustainable Infrastructure, 275g GI sheets are becoming mandatory for structural components in humid and coastal regions where standard Z120 or Z180 coatings fail prematurely.
The industry is shifting toward "Green Steel" and high-precision coatings. Modern 275g GI sheets now incorporate improved spangle control and surface passivation techniques (Cr-free) to meet environmental regulations while maintaining the structural integrity required for high-rise buildings and solar energy plants.
Founded in 2010, STEP MILLION STEEL SUPPLY CHINA CO., LTD. has evolved into a powerhouse of steel manufacturing. Our production facilities cover over 66,700 square meters of factory space, powered by more than 300 dedicated employees and eight high-frequency welded lines. With a monthly output of 100,000 tons, we are a primary source for global wholesalers.
Our R&D team consists of 20 experienced engineers who ensure that every batch of 275g GI sheet meets the most stringent international standards, including GB, ASTM, BS, and DIN certifications.
International procurement managers prioritize 275g GI sheets for their superior formability and weldability. Whether it is for HVAC ducting in the Middle East or grain silos in South America, the Z275 coating provides the necessary protection against oxidation and chemical wear.
In agriculture, our 275g sheets are used for heavy-duty greenhouse frames. In the automotive sector, they form the backbone of corrosion-resistant undercarriage parts. For the solar industry, our Zn-Al-Mg 275g variants are the top choice for mounting structures in harsh desert or saline-alkali terrains.
As a leading supplier, we support massive infrastructure projects. Our strategic partnerships with giants like Baowu Steel and Hebei Iron and Steel Group allow us to supply 700,000 tons of high-grade steel annually, ensuring supply chain stability for our clients.
Technical expertise and operational excellence define our competitive edge. With over 15 years in the industry, Step Million Steel maintains a profound understanding of material science. Our QC system involves over 20 inspectors using German and Japanese testing equipment to ensure zero compensation claims.
Step Million Steel has established long-term strategic cooperation relations with more than ten well-known enterprises such as LG Electronics and Xizi United. We sell more than 700,000 tons of steel to the country every year, with an annual turnover of nearly 4 billion yuan. Our markets cover nearly 100 countries including South America, Southeast Asia, the Middle East, and Africa.
