55% Al-Zn Coated ( GL ) Steel Coils

32 years manufacturer and supplier of hot‑dip galvalume steel coil and sheet.

Authentic Steel Group is a professional Chinese manufacturer and global supplier of hot‑dip galvalume steel (GL). Our production line meets JIS G3321, EN 10215 and ASTM A792 standards, covering grades DX51D+AZ, DX52D+AZ, DX53D+AZ, DX54D+AZ, S280GD+AZ‑S550GD+AZ.

With strict process control and advanced equipment, we offer galvalume coils in 0.10‑3.50 mm thickness, 870‑1250 mm width. Our ultra‑thin high‑strength galvalume enjoys good price competitiveness and is popular with overseas customers. Two surface options are available: anti‑fingerprint (AFP) and non‑anti‑fingerprint.

Hot‑dip galvalume steel features 55% Al‑Zn alloy coating on cold‑rolled base steel. It provides much better weather and heat resistance than ordinary galvanized steel, with longer service life.

Anti‑fingerprint (AFP) galvalume: With transparent protective passivation film, it avoids fingerprint marks, improves anti‑corrosion and surface appearance. Suitable for home appliance panels, interior decoration and high‑end indoor parts.

Non‑anti‑fingerprint galvalume: Without anti‑fingerprint coating, it is cost‑effective and easy for bending & stamping. Fingerprints may occur upon touch. Ideal for roofing, wall panels, ducts and PPGI substrates.

Galvalume steel is widely used in construction, home appliances and metal processing.
