Key Advantages

What the zinc layer delivers

GI corrosion resistance

Barrier plus sacrificial zinc protection extends service life. GI coating weight test confirms the ordered Z class.

Mechanical stability

DX51D galvanized coil and structural grades with controlled yield, tensile strength and elongation.

Forming

Suitable for shearing, stamping, lock forming and roll forming, including galvanized coil for pipe making.

Surface choice

Zero spangle galvanized coil for paint and appliances, or big spangle galvanized coil for visible structural use.

Size range

0.12–2.0mm GI coil, slit width, and GI coil weight 5–10 tons. G60/G90 galvanized coil for US-standard orders.

Export control

Online gauge, bend test, salt spray and seaworthy packing GI coil. SGS test for GI coil on request.

Spangle

Zero spangle and big spangle

Zero spangle galvanized coil

Smooth, almost no visible crystal. Preferred for PPGI substrate, appliance panels and drawing parts.

Minimized spangle

Fine crystal for fittings and ductwork that still need a paintable surface.

Big spangle galvanized coil

Regular star-like zinc flower for duct, purlin and general construction steel.
