classification
1.Galvanized steel plate is divided into ordinary electrolytic plate and fingerprint resistant electrolytic plate. Fingerprint-resistant plate is an additional fingerprint-resistant treatment on the basis of ordinary electrolytic plate, which can resist sweat. It is generally used on parts without any treatment, and its brand is SECC-N. The common electrolytic plate can be divided into phosphating plate and passivation plate. The phosphating is more commonly used, and the brand is SECC-P, commonly known as p material. Passivation plate can be divided into oiled and non-oiled.
2.give an example:
Hot dip galvanized steel sheet (SGCC) has one advantage over electro-galvanized steel sheet (SECC). The bending and section of SECC are very easy to rust. ate. The case steel plate made of this material has bright color and metallic luster. The advantage of this steel plate is good corrosion resistance.
3.Electrogalvanized sUnder the same conditions, the rust resistance of SGCC is much better. High-quality case usually adopts SECC or SGCC galvanized steel plteel sheet (SECC): uniform gray, mainly imported, fingerprint resistant, with excellent corrosion resistance, and maintains the processability of cold-rolled steel sheet. Use: household appliances, computer case shell and some door panels and panels.
Hot-dip galvanized steel plate (SGCC): dip galvanized, bright white, small zinc flakes (difficult to see), and large zinc flakes can clearly see hexagonal flowers. In China, only two factories, China Steel and Shengyu Steel Corporation in Taiwan Province, can produce high-quality materials. There is no steel factory in Chinese Mainland that can produce high-quality materials, mainly relying on imports.
