  Hot-dip galvanized steel coil/sheet (GI) is produced by continuously immersing cold-rolled steel substrate into molten zinc liquid. It features strong coating adhesion, excellent corrosion resistance and good forming performance. It is the main substrate for PPGI prepainted coils and widely used in construction, steel structure, home appliances and hardware processing.

二、Mandatory Order Parameters

1. Steel Grade

• DX51D+Z: General forming grade, common stock, for PPGI substrate, purlins and general hardware parts

• DX52D+Z: Improved bending grade for bending and light stamping

• DX53D+Z / DX54D+Z: Deep drawing grade for home appliance shells and complex stamped parts

• S220GD/S250GD/S350GD+Z: High-strength structural grade for load-bearing steel structures

2.  Zinc Coating Mass

Standard double-sided zinc coating: Z60, Z80, Z100, Z120, Z140, Z180, Z200, Z275 (g/㎡, total both sides). Higher value means better corrosion resistance and higher price. Z80-Z120 for inland use; Z180-Z275 for outdoor and humid environments.

3.  Dimension

• Thickness: 0.22mm–3.0mm (substrate thickness, excluding zinc coating)

• Width: 600mm–1500mm, custom slitting available

• Sheet: Custom cut-to-length size available

4. Surface Finish

• Normal Spangle: General industrial use, cost-effective

• Minimized Spangle: Fine surface texture

• Zero Spangle: Smooth surface without spangle, ideal for appearance parts, spraying and PPGI substrate

• Skin-passed: Improve flatness and eliminate stretcher strain

三、起订量 MOQ

MOQ: 5–10 tons for standard stock sizes. Higher MOQ for special thickness, high zinc coating and customized surface.

四、 Lead Time

 7–10 working days for stock goods; 10–20 working days for customized production, subject to extension in peak seasons.
