G550 Galvanized Steel Coil

Tntroduction of galvanized coils:

Galvanized steel coil sheet is a thin steel sheet that is immersed in a molten zinc bath so that a layer of zinc adheres to the surface. At present, the continuous galvanizing process is mainly used for production, that is, the rolled steel plate is continuously immersed in a plating bath containing molten zinc to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot dip method, but it is heated to about 500 degrees Celsius immediately after coming out of the tank, so that it forms an alloy film of zinc and iron. This kind of galvanized coil has good paint adhesion and weldability.

What is G550 steel grade?

G550 steel is a continuous hot-dipped aluminium/zinc alloy-coated structural steel with a regular spangle surface and a guaranteed minimum yield strength of 550MPa with limited ductility. Suitable for roll-forming to a minimum internal diameter of 4t. Roofing, walling and structural steel framing.

What are the properties of G550 material?

G550 steel is a hot-dipped Al-Zn alloy coated structural steel with a regular spangle surface and guaranteed minimum yield strength of 550 MPa with limited ductility. Suitable for roll forming to a minimum internal diameter of 4t.

G550 Steel:

G550 steel is a structural steel grade in the Australian AS 1397 (Continuous hot-dip metallic coated steel sheet and strip) standard. G550 means that the minimum yield strength is 550MPa.

G550 steel can provide the following hot-dip coatings:

Zinc coating (Z).

Zinc coating converted to zinc/iron alloy (ZF).

Zinc/aluminium (ZA).

Zinc/aluminium/magnesium (ZM).

Aluminium/zinc (AZ)

Aluminium/zinc/magnesium (AM).
