JIS G3321 SGCC Hot Dipped Galvanized Steel Sheet Coil DX51D Z30-Z275
Hot-dipped galvanized steel sheet is characterized by protection base metal(Fe) as corrosion resistance of zinc itself and acts effective sacrificed-anodic of zinc. It is characterized by extremely excellent workability due to produced by continuous annealing, temper rolling and after treatment process.

Features
1. Hot Dip Galvanized Steel Sheet/plate is manufactured to have a long durability, strong corrosion resistance and shiny surface.
2. Hot Dip Galvanized steel features excellent forming properties, paintability, weldability, and is suitable for fabrication by forming, pressing and bending
ABOUT SURFACE
REGULAR SPANGLE:
Regular spangle is also called normal spangle which is naturally formed without any additional treatment during galvanizing.
MINI SPANGLE:
The spangle is restrained and formed as mini spangle by reducing the lead content in the zinc liquid or by blowing the zinc powder from the equipment installed on the zinc pot.
EXTRA SMOOTH:
The mini spangle is further skin-passed to produce the extra smooth surface.
Packaging
Standard sea-worthy package:

Brief Introduction
Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized Steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized Steel Coil is an essential fabrication component.
The Protection Principle
1. Anodic reaction: Zn-2e=Zn2+
(The alloy coating loses electron, sacrificing itself in dissolution.)
2. Cathodic reaction: Fe2++2e=Fe
(Fe gains electron reaction, being protected)
