The 80g GI sheet (Galvanized Iron sheet with an 80g/m² zinc coating) represents a critical balance between cost-efficiency and corrosion resistance in the global steel market. Currently, the commercial demand for Z80 galvanized steel is surging, driven by the rapid expansion of urban infrastructure in Southeast Asia, the Middle East, and Latin America.
In the industrial sphere, the 80g coating thickness—often referred to as a medium-duty protective layer—is the preferred specification for internal structural components, ventilation ducts, and light-gauge steel framing. As global economies shift toward sustainable building materials, the longevity and recyclability of 80g GI sheets have positioned them as a cornerstone of modern "green" construction.
Unlike lighter coatings, the 80g variant offers superior protection against oxidation in humid climates, making it a "wholesale favorite" for international traders who require versatile stock that meets multiple regional standards (ASTM, EN, JIS).

Integration of AI-driven quality control in GI sheet production lines ensures that zinc distribution is uniform at exactly 80g/m², reducing material waste and enhancing surface finish for automotive and appliance applications.
Transitioning from pure zinc to Zn-Al-Mg (Zinc-Aluminum-Magnesium) coatings. While 80g pure zinc remains a standard, alloyed coatings provide even higher resistance for specialized solar mounting and offshore structures.
Global buyers are increasingly seeking "One-Stop Factory" solutions where they can procure 80g GI sheets alongside related products like pipe, flat bars, and tinplate to streamline logistics and reduce carbon footprints.
About STEP MILLION STEEL: Founded in 2010, STEP MILLION is a leading steel material supplier and manufacturer in China. Our production facilities cover over 66,700 square meters factory, and have more than 300 employees and eight High Frequency welded lines. Each line has a complete set of equipment to accomplish at least five production steps. This gives us a monthly output of 100,000 tons, half of which is exported.
Over 20 inspectors, with over 10 years’ experience, will find the suitable raw materials for your order. All of our raw materials have GB, ASTM, BS or DIN certifications. CE certifications are available upon request too. To accomplish this, we use testing equipment from Germany and Japan.
The company has established long-term and stable strategic partnership with Hebei Iron and Steel Group, Baowu Iron and Steel Group, Shougang Iron and Steel Group, and others. It sells more than 700,000 tons of steel every year, with an annual turnover of nearly 4 billion yuan.
In North America and Europe, the demand for 80g GI sheet is concentrated in the HVAC (Heating, Ventilation, and Air Conditioning) sector due to its rigid corrosion standards. In Africa and Southeast Asia, the primary application is in corrugated roofing and fence manufacturing, where the 80g coating provides the necessary protection against tropical humidity at a wholesale-friendly price point.
Home Appliance Manufacturing: 80g GI sheets serve as the "skin" for refrigerators, washing machines, and microwave ovens. The smooth surface finish allows for excellent paint adhesion and aesthetic consistency.
Automotive Industry: Used in non-critical structural parts where weight reduction and rust prevention are paramount. The DX51D and DX53D grades are frequently requested by our global automotive partners.
With an annual turnover of 4 billion yuan and 66,700 sqm of space, we possess the financial and physical capacity to handle massive wholesale orders without compromising lead times.
Our proximity and long-term contracts with Baowu and Shougang ensure we get the best raw material prices, which we pass on to our international wholesale clients.
Using Japanese and German testing equipment, every batch of 80g GI sheet undergoes spectral analysis and zinc coating thickness tests to guarantee compliance.
Located in the heart of China's steel hub, we offer expedited shipping to major ports, ensuring your supply chain remains uninterrupted and efficient.
Our 20 R&D engineers work constantly to improve coating adhesion and surface flatness, providing a technical edge that few factories can match.
Having served clients in nearly 100 countries, we understand the local customs, certifications, and payment preferences of every major market.
