What are the precautions for using galvanized sheets?

1. When storing, high humidity, acidic and damp environment is not conducive to its keeping. Choose a dry, clean and ventilated place in the house for storage to avoid erosion by dew or penetration of moisture. When storing, don't destroy the wrapping paper and shorten the storage time as much as possible.

2, the transportation should be covered with a good raincover, and must be padded with cushion wood and rubber pads, fixed with ropes, to try to avoid loading and unloading in the rain. Steel coils should be added under the cushion wood or support frame, stacking layers should not be more than two layers.

3, the steel plate needs to be used as early as possible, so as not to be too long, it may occur processing performance reduction, tensile deformation and so on. Galvanized plate processing degree is too high, may destroy the zinc layer, so before use also need to confirm the degree of processing. Flat plate by the outside world under abnormal pressure, the zinc layer will be partially detached.

4, to prevent dirt and oil powder sticking to the surface so that will affect the galvanizing effect, shall not use organic solvents to wipe the surface of the steel plate, may make the surface of the zinc electroplating coating loss or peeling.

What are the differences between galvanized sheet and cold rolled sheet

1, different physical properties

Galvanized sheet corrosion resistance is good, easy to construct, while the cold rolled sheet high hardness, the surface is very smooth.

2, different materials

The main material of galvanized sheet is hot-dip galvanized steel and electro-galvanized steel, while the main material of cold rolled sheet is stamping grade cold rolled sheet.

3、Different process

Galvanized sheet through the galvanizing process on the surface of the steel plate coated with a layer of zinc, made of alloy products, and cold rolled sheet production without heating, the appearance of a better gloss.

Selection of galvanized sheet to pay attention to what

1, before buying galvanized sheet, pay attention to understand the brand, there are many brands of galvanized sheet, the choice of space is relatively large, try to choose a big brand of galvanized sheet, quality and other aspects will be more secure.

2, galvanized sheet bought back, pay attention to storage in a dry place, do not store in the wet area, which will cause some damage to the galvanized sheet.

3, buy galvanized sheet, pay attention to check the surface of the galvanized sheet, see whether there are stains, etc., if so, such galvanized sheet is best not to buy.

4, you can choose according to the specifications of the galvanized sheet, combined with the actual situation to buy, if you buy the size of the galvanized sheet is not appropriate, it will affect the use of galvanized sheet.
