The difference between galvanized steel sheet and cold-rolled steel sheet

Time:2025-01-08

Galvanized steel sheet: Good corrosion resistance, easy construction, good match with high strength and high ductility, has become a high-strength, good formability press steel.

The main differences between galvanized steel sheets and cold-rolled steel sheets are as follows:

Physical Properties:

Galvanized steel sheets: Good corrosion resistance, easy construction, good match with high strength and high ductility, has become a high-strength, good formability stamping steel.

Cold-rolled steel sheets: High hardness, very smooth surface, generally thin sheets, can be used as stamping sheets.

Materials:

Galvanized steel sheets: The main materials are hot-dip galvanized steel sheets and electro-galvanized steel sheets.

Cold-rolled steel sheets: The main material is stamping-grade cold-rolled steel sheet, which is also divided into general-purpose cold-rolled steel sheet, deep-drawing grade, extra-deep drawing grade, and ultra-deep drawing grade cold-rolled steel sheet according to production needs.

Processing Technology:

Galvanized steel sheets: A zinc alloy product obtained by plating a layer of zinc on the surface of the steel sheet through a galvanizing process.

Cold-rolled steel sheets: Using hot-rolled coils as raw materials, rolled at room temperature below the recrystallization temperature. The production process usually includes raw material preparation, cold rolling, heat treatment, leveling, and finishing.

Application Fields:

Galvanized steel sheets: Due to its good corrosion resistance, it is widely used in applications requiring corrosion resistance, such as construction, home appliances, and automobiles.

Cold-rolled steel sheets: Mostly used in automobile manufacturing, electrical products, and other occasions with high requirements for strength and surface quality.

In summary, galvanized steel sheets and cold-rolled steel sheets have significant differences in physical properties, materials, processes, and application fields. The choice of which sheet metal depends on the specific needs and application scenarios.
