ELECTRO GALVANIZED STEEL SHEET & COIL

Electro-Galvanized steel coils and sheet are coated by applying zinc to the surface of hot rolled or cold rolled base material by the electrolytic galvanizing process.This allow for both side coating,one side coating and differential coating.They are given chromate or phosphate treatment to improve corrosion resistance or paintability.

CHARACTERISTICS OF ELECTRO GALVANIZED IRON

Corrosion Resistance

To enhance the anti-corrosion property, Electro-Galvanized steel is chemically treated or oiled to protect the zinc coating from white rust. Rust is positively retarded even when the base metal is exposed to the atmosphere during fabrication.

Anti-Finger Print (AFP)

The AFP film can be touched by fingers without print left on its surface and has been approved by several laboratory tests.

Formability

The strong bonding AFP film with self-contained lubricant agent is very good in formability without zinc dust loosening during pressing and slitting process.

Weldability

The AFP film is easy to apply spot or seam welding as with plain steel sheets.

Excellent Paint Adhesion

Electro-Galvanized steel is free from spangles and pinholes.Surfaces are teated with phosphate or chromate to assure improved paint adhesion as well as a smooth and pleasant finish.The AFP film is compatible with most regular paint which may appliedin the coating process.

Resistance to Cleaning Agent

Whenever it is necessary to clean surface of the Electro-Galvanized coil with AFP coating some cleaners (PH 9.5 -10.0) such as Aliphatic & halogened solvents are recommended.Low alkalinity cleaners are also suitable.

Variety of Products

Electro-Galvanized steel is available with bothside, one side or defferential coating,as well as chromatic,phosphatic or oiling treated by application.
