General galvanised steel strip processing process (brief introduction):
1) pickling (to remove iron oxide on the surface of the strip)
2) Cold rolling (rolling thin, improve wall thickness tolerance, surface finish)
3) galvanising (forming a zinc-iron alloy layer + zinc layer on the iron substrate, anti-corrosion, beautiful)
4) Delivery (after some products are slit lengthwise and slit, they are delivered in a net edge state)
Special Note: Some of the thicker galvanized steel strip (such as thickness of 2.5mm or more), do not need cold rolling rolling, pickling directly after galvanizing, called pickling straight plating, this mainly depends on the downstream product requirements.
