For laboratories, galvanized steel sheets are better than cold-rolled steel sheets.
Definition and characteristics of galvanized steel sheets and cold-rolled steel sheets
1. Under the same conditions, galvanized steel sheets have better corrosion resistance than cold-rolled steel sheets. The coating of galvanized steel sheets (galvanized steel sheets are coated with a layer of zinc) can largely prevent the steel sheets from rusting, oxidation, and corrosion resistance. Hot-dip galvanized steel sheets are more corrosion-resistant than cold-rolled sheets. The corrosion resistance of cold-rolled steel sheets is slightly worse. When in contact with air, the steel sheets will oxidize and rust.
2. Characteristics of galvanized steel sheets Strong corrosion resistance, good surface quality, conducive to deep processing, economical and practical, the drawing performance of cold-dip galvanized steel sheets is not as reliable as that of cold-rolled steel sheets.
3. Galvanized steel sheets are made of cold-rolled steel sheets as raw materials. After pickling and surface galvanizing, a layer of zinc coating is formed on the surface of the steel sheets. They are mainly used in the fields of testing, construction, machinery, electrical appliances, and home appliances. Cold-rolled steel refers to a thin plate formed by rolling hot-rolled steel at room temperature, which is commonly used in automobiles, freezers, furniture and other fields.
The characteristics of cold-rolled steel are high strength, good toughness, clear texture and easy processing.
The effect of use in different environments The effect of galvanized steel and cold-rolled steel is also different in different environments.
In terms of corrosion resistance, galvanized steel has very strong corrosion resistance and can be used in harsh environments; while cold-rolled steel has relatively weak resistance and is easily oxidized because it is not coated with special coatings or metals on the surface.
In terms of wear resistance, cold-rolled steel is harder and easy to deform and crack; while galvanized steel has a zinc coating on the surface, which can enhance wear resistance and is not easy to damage.
In terms of processing, cold-rolled steel has no surface coating and has a high hardness, which is very easy to process and shape; while galvanized steel has a zinc coating on the surface, which requires special treatment during processing, which will affect the processing quality.
Therefore, if obvious advantages in corrosion resistance and wear resistance are required, galvanized steel plates are recommended for laboratory benches; if processing and forming applications are required, cold-rolled steel plates are recommended.
