The ZF100 Zinc Iron Sheet, commonly referred to in the industry as Galvannealed steel with a 100g/m² coating weight, represents a pinnacle in metallurgical engineering. Unlike standard galvanized steel, ZF100 undergoes a specialized heat treatment process (annealing) after the hot-dip stage. This causes the iron from the steel base to diffuse into the zinc coating, creating a unique Zinc-Iron alloy layer.
In the current global industrial landscape, the demand for ZF100 has surged, particularly in North America, Europe, and East Asia. As the automotive industry transitions towards Electric Vehicles (EVs), the need for materials that offer superior weldability and exceptional paint adhesion—without sacrificing corrosion resistance—is paramount. ZF100 provides a matte, velvet-like surface that is ideal for high-precision painting, making it the preferred choice for external body panels and internal structural components in modern manufacturing.
The trend is moving toward "Thin-Gauge, High-Strength" sheets. Factories are now integrating Magnesium into the Zinc-Iron matrix to further enhance edge protection and longevity in harsh environments.
Global procurement standards now prioritize "Green Coating" processes. As a leading supplier, we utilize energy-efficient induction heating during the galvannealing process to reduce carbon footprints.
AI-driven quality monitoring ensures that every millimeter of the ZF100 sheet maintains a consistent alloy phase, meeting the strict requirements of Tier 1 automotive suppliers.
STEP MILLION STEEL SUPPLY CHINA CO., LTD., founded in 2010, is a leading steel material supplier and manufacturer in China. Our production facilities cover over 66,700 square meters and house more than 300 employees.
With eight High Frequency welded lines, we achieve a monthly output of 100,000 tons, half of which serves the global market. Our facilities include a molding workshop with 20 R&D engineers, each possessing over 10 years of experience in metallurgical science.
"Serve the public, focus on quality." We have established strategic cooperation with world-renowned enterprises such as LG Electronics and Xizi United.
Located in the heart of China's steel hub, we maintain strategic partnerships with Hebei Iron and Steel Group, Baowu Group, and Shougang Group, ensuring stable raw material supply and competitive pricing for ZF100 sheets.
Over 20 inspectors with 10+ years of experience verify every batch. Utilizing testing equipment from Germany and Japan, we guarantee compliance with GB, ASTM, BS, and DIN certifications.
With an annual turnover of nearly 4 billion yuan and 700,000 tons sold annually, our logistics network ensures expedited delivery to nearly 100 countries across Southeast Asia, the Middle East, and South America.
Whether it's DX51D, DC53D, or specific ZF coating weights, our 20 R&D engineers provide customized solutions tailored to specific industrial humidity and mechanical stress requirements.
The ZF100 Zinc Iron Sheet is engineered for versatility across diverse climates and industries.
Used in tropical regions where high humidity and UV exposure demand a coating that won't peel. The Zn-Fe alloy provides an anchor for automotive primers, preventing "creep" corrosion.
In high-end manufacturing centers like South Korea and Germany, ZF100 is the standard for refrigerator panels and washing machine drums due to its spot-welding efficiency.
In arid or coastal solar farms, ZF100 and its variants (like Zn-Al-Mg) offer the structural integrity and corrosion resistance needed for 25-year lifespans.
With over 15 years of industry experience, our commitment to quality is matched by a pricing strategy that ensures cost-effectiveness without compromising material integrity. We provide comprehensive solutions within 48 hours and address all inquiries within 24 hours.
Our service model includes flexible cooperation terms, such as accepting small-scale initial orders to build trust before long-term partnerships. Enhanced payment terms and expedited delivery schedules are integrated to maximize value for global clients.
