For laboratories, galvanized steel is better than cold rolled steel.
Definition and characteristics of galvanized steel and cold rolled steel plate
1, the same conditions in terms of corrosion resistance, galvanized steel than cold-rolled steel performance is better, galvanized steel coating (galvanized steel coated with a layer of zinc) can be largely prevented from rusting, prevent oxidation, corrosion resistance and other characteristics of hot-dip galvanized steel than cold-rolled steel corrosion resistance, cold-rolled steel is slightly worse than the corrosion resistance of steel, in contact with the air when the steel plate will oxidize and rust.
2, galvanized steel sheet features strong corrosion resistance, good surface quality, conducive to deep processing, economical and practical, cold galvanized steel sheet is less reliable than cold rolled steel sheet tensile properties.
3, galvanized steel is cold rolled steel as raw material, after pickling and surface galvanized goods, so that the surface of the steel plate to form a layer of zinc-plated steel, mainly used in laboratory, construction, machinery, electrical appliances, home appliances and other fields. Cold rolled steel plate refers to the hot rolled steel plate at room temperature by rolling to form a thin plate, commonly used in automobiles, freezers, furniture and other fields.
The cold rolled steel plate is characterized by high strength, good toughness, clear texture, easy processing and molding.
Effect of use in different environments In different environments, the use of galvanized steel and cold rolled steel plate is different.
Anti-corrosion Galvanized steel sheet has very strong anti-corrosion properties and can be applied in harsh environments; while cold rolled steel sheet is relatively weak in resistance and prone to oxidation because it is not plated with special coatings or metals on the surface.
Abrasion resistance Cold rolled steel plate is harder and prone to deformation and rupture; while galvanized steel plate has a zinc coating on the surface, which enhances abrasion resistance and is not easy to be damaged.
Processing aspect Cold rolled steel plate has no surface coating and is hard, very easy to process and shape; while galvanized steel plate requires special treatment when processing due to the zinc coating on the surface, which will affect the processing quality.
Therefore, if you need to be in the anti-corrosion, wear-resistant aspects of the obvious advantages of the laboratory bench selection is recommended to choose galvanized steel; and if you need to carry out processing, molding applications, it is recommended to choose cold-rolled steel.
