Heavy zinc mass hot dipped galvanized steel strip with premium corrosion barrier performance. Specially manufactured for harsh outdoor conditions, ground grounding systems, solar panel mounting structures, and coastal infrastructure projects. Thickness up to 4.5mm with a robust zinc finish.
Industrial engineering projects, including electrical utility grounding fields, solar photovoltaic tracking systems, maritime storage facilities, and highway divider systems, require structural materials that offer long-term resistance to atmospheric corrosion. To meet these rigorous specifications, Authentic Steel manufactures heavy-gauge hot dipped galvanized steel strip options with zinc coating capacities that can reach up to 600g/m² on both sides.
Our production facility uses high-temperature metallurgical dipping lines that create a deep zinc-iron alloy layer on the base metal. This advanced structural design provides excellent physical resistance against peeling and wear, even when the steel strips are driven deep into rocky soils for lightning grounding systems. Additionally, the thick zinc layer provides continuous cathodic protection, meaning that if the steel becomes scratched or exposed during field cutting, the surrounding zinc will sacrifice itself to protect the underlying steel from rust.
Authentic Steel carefully balances structural hardness with material elasticity across our entire catalog. This allows engineering clients to roll-form thick 4.5mm steel profiles into complex solar mounting channels without developing micro-fissures along stressed bends. Our close proximity to the port of Tianjin allows us to efficiently manage transit workflows, offering flexible shipping arrangements and lowering total import costs for international buyers.
As the dedicated export division of Winroad Group, our commercial teams have supported international procurement managers since 1994, delivering reliable metal supplies to 78 countries. We provide full material traceability for every container, including mill test certificates, certified chemical readouts, and detailed weight documentation.
