Information Summary:
Galvanized sheet and cold-rolled sheet are both commonly used plates in production and life, so what are the differences between these two plates? What is the difference between galvanized sheet and cold-rolled sheet? What are the differences? It is recommended to take a look at the following list of differences between galvanized sheet and cold-rolled sheet, hoping to help you understand these two plates.
The difference between galvanized sheet and cold rolled sheet
1. Galvanized sheet: Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is an economical and effective anti-corrosion method often used, and about half of the world's zinc production is used in this process.
2. Cold-rolled sheet: Cold-rolled sheet is a product made of hot-rolled sheet through cold pressure processing. Due to multiple passes of cold rolling, its surface quality is better than that of hot-rolled sheet, and after heat treatment, good mechanical properties can be obtained.
Second, the difference between galvanized sheet and cold-rolled sheet
1. Different plates
Galvanized sheet: hot-dip galvanized steel sheet, electro-galvanized steel sheet
Cold-rolled sheet: general cold-rolled sheet, stamping-grade cold-rolled sheet, deep-drawn, extra-deep-drawn and ultra-deep-drawn cold-rolled sheet
2. Different processes
Galvanized sheet: Galvanized sheet is a composite product made by galvanizing and plating a layer of zinc on the surface of the steel plate.
Cold-rolled sheet: Cold-rolled sheet is made of hot-rolled sheet as raw material, and the production process usually goes through major processes such as raw material preparation, cold rolling, heat treatment, leveling, and finishing.
3. Different physical characteristics
Galvanized sheet: With a good combination of high strength and high ductility, it has become a kind of high strength and good formability stamping steel.
Cold-rolled sheet: high strength, high hardness, high surface finish, generally thin sheet, can be used as a stamping plate.
Summary: The above is the entire content of the differences between galvanized sheet and cold-rolled sheet. In fact, the difference between galvanized sheet and cold-rolled sheet is simply that galvanized sheet can be divided into hot-dip galvanized sheet and cold-dip galvanized sheet in terms of production methods. There are certain differences in the substrate of cold-dip galvanized sheet, and the common ones are cold-rolled sheet and hot-rolled sheet.
