EG Steel Coil and Sheet Specifications
Electro-galvanizing is a galvanizing process in which a layer of zinc is electro-chemically deposited on the surface of cold rolled steel. The thickness of the zinc layer is usually in the range of 5-20 μm and is available in bright zinc, matte, and colored galvanized forms. Wanzhi Group provides EG steel and HDG steel in various styles and sizes following international standards such as JIS, EN, ASTM, GB, etc. as well as further processing services.

Process
- Pre-treatment: degreasing, acid washing, water washing. Pre-treatment: Degreasing, acid washing, and water washing (to remove impurities on the steel surface).
- Zinc plating: Immerse the substrate in the electrolytic solution, and energize it to deposit zinc ions on the steel surface.
- Post-treatment: passivation, oiling and drying. (Enhance the corrosion resistance of steel, and prevent oxidation.)
Benefits of EG Steel
EG steel has a uniform, smooth surface coating, free of zinc spangle and particles, combining the mechanical properties of cold rolled steel coil with the corrosion resistance of zinc, and maintaining stable properties during precision stamping and bending processes.
- Good surface quality
- Good precision machinability
- Aesthetically pleasing
- Cost-effective
- Wide range of applications
EG Steel Applications
EG steel is used in electronics and automotive interiors to meet the needs of automotive, home appliances, electronics, and decorative applications for high surface quality, fingerprint resistance, aesthetics, scratch resistance, precision stamping, lightweight, and rust prevention.
- Car body, car interior decoration, battery casing
- Refrigerator shell, washing machine shell, air conditioner shell
- Computer chassis, cell phone bracket, chassis cabinet
- Light steel keel, decorative panels
- Metal cans, instrument boxes, etc.

Electro-Galvanized vs Hot-Dip
| Comparison | Electro-galvanized | Hot-dip galvanized |
| Process | Normal Temperature Processing, Electrolytic Deposition | High-Temperature Processing |
| Zinc layer | 5–20 microns (conventional) | 40–150 microns (customized) |
| Surface | Smooth, zero spangle | Rough, zinc spangle |
| Corrosion resistance | medium | high |
| Processing | precision stamping, bending | slitting, bending, molding |
| Environmental protection | wastewater from electrolysis needs to be treated | zinc fumes from high temperatures need to be filtered |
| Processing cost | high | low |
| Applications | automotive, home appliances, electronic | building construction, industrial production |
Best Electro-Galvanized Steel Price
The processing cost of EG steel is high (the process is more complicated), but the cost of zinc consumption is low, and the energy cost is low, so the unit price of electro-galvanized material is higher, the price is in the range of 600-1200 US dollars per ton, leave the thickness of the steel, zinc layer, width, surface treatment, and other requirements you need, get a free quote from Wanzhi Group!

QA – EG steel Coil and Sheet
How to choose electro-galvanized steel for appliances?
Factors to consider when choosing electro-galvanized steel for appliances include corrosion resistance, appearance quality, mechanical properties, cost-effectiveness, and compliance, and materials for appliances need to be compliant with industry standards such as RoHS, and so on.
How to choose EG steel thickness for car parts?
The thickness of steel for car parts depends on the application, body panels need to be 5–15 microns thick for corrosion resistance and compliance, while electro-galvanized steel for car chassis needs to be 20–25 microns thick for higher corrosion resistance.
What are the corrosion resistance tests for electro-galvanized sheets?
The corrosion resistance of electro-galvanized sheets can be evaluated in several ways: Salt spray test, Neutral salt spray test, Cyclic corrosion test, Field exposure test, etc.
