Equipped with 2 dedicated galvanizing production line delivering an annual output of 80,000 tons, our product portfolio complies with JIS G3302, EN 10147 and ASTM A572 standards, covering material grades including SGCC, SGCH, DX51D‑DX54D, G350, G450 and G550.

Backed by sophisticated production facilities and rigorous full‑process quality management, we supply premium hot‑dipped galvanized coils ranging 0.10‑3.50mm in thickness and 870‑1250 mm in width. Our high‑strength ultra‑thin galvanized steel (0.10‑0.25 mm) enjoys prominent price competitiveness and is well‑received by overseas buyers.

Hot‑dipped galvanized steel coil originates from cold‑rolled substrate with double‑sided zinc coating. Zinc plating serves as a highly cost‑efficient anti‑corrosion solution for steel substrates. By imparting excellent rust‑resistant performance to cold‑rolled base material, zinc coating greatly extends the service life of galvanized coils compared with bare hot‑rolled and cold‑rolled steel products.
