What are the differences between galvanized sheet and cold rolled sheet

In our daily lives, especially when it comes to home decoration, we have a certain understanding of the materials used for home decoration. So what is the difference between galvanized sheet and cold-rolled sheet we see in our daily lives? Today, the editor will talk to you about the differences between cold rolled sheet and galvanized sheet? I hope it can bring help to everyone. Interested friends can leave a message in the comment section!

Galvanized sheet refers to a steel plate with a layer of zinc on its surface, and galvanizing is a commonly used economical and effective anti-corrosion method! Galvanized sheet is a thin steel plate coated with a layer of metallic zinc to prevent corrosion on the surface of the steel plate and extend its service life. This type of zinc coated steel plate is called galvanized sheet. Cold rolled steel plate is an abbreviation for cold-rolled steel plate. The base material of cold rolled sheet is hot-rolled steel plate, which is generally relatively thin and has a thickness of 0.2-3mm. The surface is bright and flat, somewhat like stainless steel.

Cold rolled sheet is a product obtained by cold pressing hot rolled thin plates. Due to multiple passes of cold rolling, its surface quality is superior to that of hot rolled thin plates. After heat treatment, good mechanical properties can be obtained.

1. Physical properties: Galvanized sheet has strong corrosion resistance, while cold rolled sheet has good drawing performance.

2. In terms of technology, cold rolled sheets are products obtained through hot rolling technology, which is slightly more complex and free from defects. The surface of galvanized sheets is treated with rust removal technology, and there are pits or oxidation phenomena on the surface.

3. Due to different physical properties, galvanized steel plates are more resistant to corrosion than cold-rolled plates. The characteristics of galvanized steel sheet are strong corrosion resistance, good surface quality, convenience for deep processing, and economic practicality. The drawing performance of galvanized steel sheet is not as reliable as that of cold-rolled sheet, and galvanized sheet is not as easy to weld as cold-rolled sheet, causing damage to the zinc layer during welding.

4. The application scope is different, with cold-rolled sheet used in automotive manufacturing, electrical appliances, etc., and galvanized sheet used in the construction industry.
