Products Description
Electro galvanized steel sheet in coil supplier:
Achieve corrosion resistance and uniform thickness with electro-galvanized steel sheet and coil from GNEE Steel Company.
Electro-galvanized (EG) steel is produced by covering one or both sides of a carbon steel workpiece with a corrosion-resistant zinc coating. This method provides a very consistent thickness of varnish to the steel surface, thereby enhancing the forming and joining operations. Due to its corrosion-resistant properties, electro galvanized coil is commonly used in the construction, automotive, energy, agricultural, military and defense, transportation and manufacturing industries.
Our electro-galvanized products comply with ASTM A-879.As a full-service steel and electro eg galvanized steel coil dealer, we tailor our steel to meet your specifications. We provide a variety of processing services such as ring cutting, cutting to length, pickling, smoothing, stretch straightening, coating, spray painting, etc.

How is eg coil electro-galvanized steel made?
Electrochemical process:
The electrochemical process involves immersing the steel in a cold zinc bath while an electric current is passed through it. This is also called electroplating.
Electroplated zinc, electrolytic bath zinc acts as an anode to protect the steel. The anode is the positively charged electrode (electric current) that attracts electrons and anions (negatively charged ions). The cathode protects the steel from corrosion. The cathode is the negatively charged electrode that attracts cations (positively charged ions).
A conversion coating is then applied to the metal to further enhance corrosion protection. This creates an additional layer of zinc and chromium hydroxide, which gives the material its blue color.
Benefits of electrogalvanizing:
The electrochemical process creates a thinner deposit of zinc, giving the steel greater corrosion resistance and improved performance.
Electro-galvanized surfaces are easy to paint. This is an important quality for industries that manufacture products such as trailers, appliances, and agricultural equipment.
The difference between electro galvanizing and hot galvanizing:
1.There is a big difference in the amount of galvanizing between hot-dip galvanized sheet and electro-galvanized sheet. The amount of hot-dip galvanized sheet cannot be too small. Generally, the minimum is 50-60g / m2 on both sides, and the maximum is 600g / m2. The galvanized layer of the electro galvanized sheet can be very thin, the minimum is 15g / m2.
2.Hot-dip galvanized sheet and eg/egi coil sheet are fundamentally different in the coating structure. There is a slightly brittle compound layer between the pure zinc coating of the hot-dip galvanized sheet and the steel strip substrate. When the pure zinc coating crystallizes, zinc flowers are mostly formed, and the coating is uniform and free of pores. The zinc atoms of the electro galvanized sheet layer are only deposited on the surface of the steel strip, and they are attached to the surface of the steel strip by physical action.
