Brief Introduction
The electro-galvanized steel sheet is manufactured by firstly going through the rolling via the cold continuous rolling unit, annealing treatment via the CAPL unit, and then getting to the electro-galvanizing unit for surface cleaning. Under the action of electric field, the zinc deposits onto the surface of the steel strip from the zinc salt solution to form the surface zinc coating.

The continuous electro-galvanized cold rolled steel plate and steel strip are fit for the industries covering automobile, electronics, home appliance, etc. The main delivery mode is the coil form product. The steel plate and steel strip through transverse or longitudinal shearing can also be available.

Uses
The electro-galvanized steel sheet can be processed with phosphating, passivation, oiling, fingerprint resistance, alloying, etc. Its mechanical property refers to the corresponding base plate.

Product Grade and Standard (table 3)

Variety	Standard	Category	Grade	Purpose and Characteristic
Electro galvanizing	Q/BQB431-2000	Electro galvanized steel strip	BLCE Z, BLDE Z, BUSDE Z, BUFD Z, BSUFDE Z, B240ZKE Z, B280VKE Z, B340VKE Z, B400VKE Z, B170P1E Z, B210P1E Z, B250P1E Z, B210P2E Z, B250P2E Z, B280P2E Z, B140H1E Z, B180H1E Z, B180H2E Z, B210H2E Z, B250H2E Z	This kind of electro-galvanized steel sheet has the type for drawing and high strength cold forming, as well as the dent resistance type. Through the electro galvanizing, the anticorrosion ability is raised significantly.
Electro galvanizing	Q/BQB431-2000	Electro galvanized nickel alloy steel strip	BLCE ZN, BLDE ZN, BUSDE ZN, BUFDE ZN, BSUFDE ZN, B240ZKE ZN, B280VKE ZN, B340VKE ZN, B400VKE ZN, B170P1E ZN, B210P1E ZN, B250P1E ZN, B210P2E ZN, B250P2E ZN, B280P2E ZN, B140H1E ZN, B180H1E ZN, B180H2E ZN, B210H2E ZN, B250H2E ZN	The product falls into the type for drawing and high strength cold forming, as well as the dent resistance type. Its anticorrosion capability is five times stronger than that of pure zinc coated product with the coating of the same thickness.

Surface Treatment Classification (table 4)

Surface Treatment Type	Mark	Use	Description
Phosphating	P	Painting	Phosphating mainly makes surface preparation for the following painting and also plays the function of eradicating the generation of the white rust on the surface.
Chromatizing	C	General use	Chromatizing is mainly for preventing the generation of white rust during the transportation and storage process.
Oiling	O	Pretreatment plus coating	Oiling process is also the effective measure for preventing the product from the white rust.
Fingerprint resistance	N	Electrical appliance	This measure can boost the fingerprint resistance and anticorrosion ability.

Note: The surface treatment mark can combine with the grade arbitrarily, such as SECC-P, SECD-N, SECE-O, etc.
