Product Description

GI galvanized galvanised steel coil brief introduction
Galvanized steel coil is proceeding by the chemistry degrease and electric analysis with the cold rolled steel coil and sheet, clean the oils on the surface of steel, sufficiently heated to the proper temperature for zinc coating, pass by level up, strain rectify, and then passivation or annoit etc. Hot-dip galvanizing is the process of applying a protective zinc coating to steel sheet or iron sheet, to prevent rusting.

GI galvanized galvanised steel coil advantages
Hot dipped zinc on the surface of cold rolled steel sheet improves anti-erode and prolong the usage period of steel coil. The galvanized steel coil looks more beautiful and artier.

GI galvanized galvanised steel coil applications
Galvanized steel coil is widely used in light industry, home appliances,automobile and architecture (as light steel keel, air conditioner system, panel,roof sheet, rolling door ). It is also the base materials for color coated steel sheet.

GI galvanized galvanised packing details-standard export sea worthy packing
All steel rolls have standard seaworthy export packing. From inside to outside, there are anti-rust cloth, plastic film, stainless steel guard board, strapping and lock catch.
