Source certified galvanized steel coil directly from Authentic Steel (Winroad Group). Featuring thickness options from 0.1mm to 3.5mm, reliable corrosion resistance, and global port delivery from Tianjin. High zinc coating uniformity ensures excellent forming capabilities for diverse industrial processing lines.
When managing international procurement for industrial projects, reliability and direct factory accountability are paramount. Authentic Steel, serving as the professional international export arm of Winroad Group, brings over three decades of advanced steel manufacturing expertise straight to your supply chain. Since our establishment in 1994, we have consistently refined our hot-dip galvanizing lines to provide the global market with premium-grade material that excels in structural longevity and corrosive resilience. Our strategic facility setup near the bustling Tianjin port guarantees optimized inland logistics, lower transit risks, and swift vessel loading for shipments to over 78 countries.
Our production infrastructure supports an extensive capability range tailored to meet diverse industrial drawing requirements. We maintain strict control over both the cold-rolled substrate selection and the subsequent metallurgical zinc bonding process to deliver consistent dimensional accuracy.
Material Thickness Capability: Available from 0.1 mm to 3.5 mm to support both light-gauge profiling and heavy structural work.
Coil Width Selection: Ranging standardly from 870 mm up to 1250 mm, with precise slitting services available upon request.
Zinc Coating Weight Options: Engineered from 30 g/m2 up to a heavy-duty 600 g/m2 for extreme atmospheric exposure.
Every single galvanized steel coil leaves our mill after passing uniform coating verification. Depending on your final manufacturing application, we offer precision engineered surface aesthetics including classic Regular Spangles for robust industrial ducting, Minimized Spangles for modern machinery housing, and completely smooth Zero Spangles. The Zero Spangle variant acts as an excellent bonding substrate for high-durability PPGI color coating production lines, preventing paint delamination over extended life cycles.
Long-distance ocean freight demands impeccable protective packaging. We utilize a multi-layer heavy-duty export wrapping system combining moisture-proof synthetic barrier paper, heavy steel inner and outer peripheral rings, and robust steel strapping bands. This meticulous layout ensures that your steel arrives at your facility entirely free of white rust, physical deformation, or edge damage caused by rough handling during sea transit. Our dedicated export engineering team provides full transparency with complete material test certificates (MTC) accompanying every shipment.
