We ofen choose metal sheets to produce metal enclosures for electronics, metal box can protect and looks nice.
And do anodizing or powder coating on surface. Like: spray, galvanized...
Then, what is the difference between electrolytic plates and galvanized sheets?
The galvanized steel sheet has the characteristics of acid resistance, rust prevention, corrosion resistance, long service life, light material, and the appearance is also relatively beautiful, so it is widely used on the surface of instruments and building materials. There are usually two kinds of galvanized steel sheets - hot dip galvanizing and electroplating galvanizing. The galvanized sheet has good rust prevention effect, but is susceptible to chemical corrosion, and the surface zinc layer hinders the welding quality due to surface roughness. High impact paint quality;
The electrolytic plate is chemically treated on the surface of the steel plate with a low cost, but the rust-proof performance is not good for the galvanized sheet. If the galvanized sheet is not painted in the outdoor, it is recommended that you use the electroplating plate to paint the best, especially in places with corrosive substances. The advantage is that the lacquer layer has good adhesion.
Our factory usually use electrolytic plates to produce electronic equipment housing.
