I often do these processes in Lecong, and the steps are as follows: (The board width is different and the price is different, taking 10 10mm as an example).

Pickling (120 yuan)-calendering (700 yuan)-finishing and straightening (80 yuan)-hot dip galvanizing (about 1000 yuan).

Total 1900 yuan. The price of 20 10 cold-rolled sheet is basically the same as that of galvanized sheet, and galvanized steel is completely at a loss.

Processing 3.0mm hot rolled sheet into 0.5mm galvanized sheet is at least cheaper 1000 yuan/ton than buying 0.5 galvanized sheet in the market.

1 100- 1200 is the market price difference comparison between 3.0 hot-rolled coil and 0.5 galvanized sheet.

The actual processing cost is subject to the quotation of Shunde Chencun Colorful Company, which specializes in color-coated boards.

It is sprayed on the basis of zinc plating. 1000 yuan hot galvanizing is for 0.5* 10 10.

The thickness of zinc layer is 80g/m2. The width and thickness of the plate are different, and the price is also different. The wider the width, the more expensive it is.

Moreover, the thinner the plate, the more expensive it is, and the thicker the zinc layer, the more expensive it is, and the quality of zinc plating made by ourselves is much worse than that of the original factory.

And it's more expensive than the original one. I suggest taking the original one.
