Steel Strip Plating
Steel Strip Plating

EGL and ETL are mainly used in automotive panels, appliance panels and food packaging cans. Strips in large coils are produced through a continuous production process and then cut to the required specifications after electroplating is completed.

APPLICATION & PRODUCTION PROCESS
Application & Principle
Electro-galvanized plate(EGL) Electro-galvanized plate is characterized by good corrosion resistance, processability, weldability and painting, mainly used in automobile, home appliances, light industry and other industries. Electro-galvanizing products include double-sided, single-sided and differential coating depending on different coating; there are also passivation, phosphating, fingerprint proof and other products according to the different post-plating treatment.
Electrolytic tinplate(ETL) Electrolytic tinplate is mainly used in packaging industry because of its excellent corrosion resistance, beautiful appearance, high strength, light weight, good(deep stamping) formability, and good resistance to organic substance, dilute acid, alkali and salt corrosion. Tinplate products can be further divided into two categories: food (i.e. food packaging products) and general products (i.e. non-food packaging products).

PRODUCTION PROCESS INRODUCTION
After several pre-treatment processes, the cathodic strip will be treated in a series of electrolytic cells. The electrolytes in these cells contain soluble zinc or tin ions, which will be electrodeposited on the surface of the strip after electrochemical reaction.
Reaction Mechanism
Anodic reaction(on anode surface): 2H 2O-4e →O 2↑ + 4H +
Main cathodic reaction(on steel plate surface):
Zn 2++ 2e → Zn / Sn 2++ 2e → Sn
Cathode surface reaction:
2H 2O + 2e → H 2↑ + 2OH -
