Electro‑Galvanized (EG) Steel Plate is produced through an electrolytic zinc‑coating process, resulting in:
A uniform, thin zinc layer
A smooth, bright, defect‑free surface
Excellent paintability and formability
Precise thickness control
Superior surface quality compared to HDG
EG steel plate is widely used in automotive manufacturing, home appliances, electronics, and precision‑formed industrial components where surface quality is critical.
