What is the difference between galvanized sheet and cold rolled sheet

Whether galvanized sheet or cold rolled sheet, it is relatively common in our daily life. Although the plates look similar on the outside, the color is metal. But there are some differences between the two, and we need to distinguish them.

First, the difference between galvanized sheet and cold rolled sheet

1, the first difference is reflected in their physical properties, the choice of galvanized sheet, its surface corrosion resistance is relatively strong, and conducive to post-processing, but the cold-rolled sheet ductility can be slightly better, especially in the welding, galvanized sheet is easy to be damaged, but cold-rolled sheet is not easy to suffer damage.

2, the second difference is the performance of the material, if it is cold rolled plate, it is through hot rolling, later through the cold rolling technology to get the product, need to go through multiple steps, so the processing is slightly more complicated, but it can get better mechanical properties.

3, the third difference is the process, cold rolled plate in the production process does not need to be heated, so there will be no defects, better surface quality, gloss is relatively strong, and the size is more accurate. But galvanized sheet is through some way of rust removal, the surface may lead to some pitting or oxidation phenomenon.

4, the fourth difference is their range of application is different, cold rolled plate is generally used in automobile manufacturing or electrical appliances are widely used. Galvanized sheet is generally used in the construction industry, such as tiles on the roof can use this plate, in addition, kitchen utensils can also choose galvanized sheet made of.

Two, galvanized sheet and stainless steel difference

Some people found galvanized sheet and stainless steel appearance is the same, in fact, compared with the two also have certain differences. For example, galvanized sheet is coated with a layer of metal zinc on the iron sheet, which can achieve a certain anti-corrosion effect. And there are two kinds of process, one is cold plating, and one is hot plating, after a long time may be used on the surface of zinc will be lost, but stainless steel will not be anticorrosive, it is through trace elements, so that it can change its composition, to achieve the effect of anticorrosion, so the two production process is different.
