Difference Between Galvanized Steel Sheet and Cold Rolled Steel Sheet
Differences in physical characteristics
The surface layer of galvanized steel sheet has strong corrosion resistance, good process performance, and is conducive to production and processing, but the draw ability of galvanized steel sheet is not as reliable as that of cold-rolled wholesale galvanized steel roofing sheet, and the zinc layer is very easy to be damaged during electric welding.
Generally, a cold-rolled steel sheet is a commodity obtained by hot-rolled metal sheet production and processing according to cold working pressure, because, after multiple cold-rolling, its process performance is better than the hot-rolled metal sheet, after quenching and tempering treatment can obtain excellent physical properties.
Processing technology differences
Since the heating process is not carried out during the processing of cold-rolled steel plates, the shortcomings such as black spots and iron oxide scales that are often found in hot rolling are not found. The process performance is good and the smoothness is high. It can consider some unique application regulations, such as electromagnetic induction characteristics, low alloy plate characteristics, etc. The galvanized steel sheet is a commonly used economic development and reasonable anti-rust treatment method. About half of the world’s zinc production is a cold-rolled galvalume corrugated roofing sheet price using this kind of processing technology.
Cold-rolled steel plate: mostly used in the automobile industry, household appliances, etc., such as refrigerators, electric water heaters, etc. galvanized steel plate: the key is used in engineering construction, light industrial machinery business services and other manufacturing industries. Among them, the construction industry is suitable for roof tiles; the metallurgical industry uses it to manufacture household appliance casings, kitchen supplies, etc.
