Electro-Galvanizing Steel Coil Applications
(1) Home appliances and electronics industry
Refrigerator/washing machine panel: smooth surface, can be directly sprayed or coated
Electronic chassis (servers, switches): electromagnetic shielding + rust prevention
Lamp accessories: precision stamping
(2) Auto parts
Interior parts: instrument panel bracket, seat slide (need to be sprayed for aesthetics)
Fuel tank: good weldability, resistant to fuel corrosion
(3) Construction and hardware
Light ceiling keel: used in dry indoor environment
Hardware (hinges, brackets): low-cost rust prevention solution
Will electro galvanized steel DC01+ZE rust?
Will rust. The zinc layer of electrogalvanized steel DC01+ZE is thinner and has a good anti-rust effect in a dry indoor environment, but it will rust in a humid, acidic, alkaline or outdoor environment. When the zinc layer is worn or white rust (basic zinc carbonate) is found, apply protective paint in time
