Zinc 40g/m2 regular spangle galvanized coils GI coils from China mill

Zinc 40g/m2 regular spangle galvanized coils GI coils from China mill For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.

Product Description

Zinc 40g/m2 regular spangle galvanized coils GI coils refers to the surface of metal, alloy or other materials plated with a layer of zinc to play a beautiful, rust and other functions of the surface treatment technology.Zinc 40g/m2 regular spangle galvanized coils GI coils main methods used are hot dip galvanizing and electric galvanizing.

Generally speaking, Zinc 40g/m2 regular spangle galvanized coils GI coils is to take the substrate (usually cold rolled) in the liquid zinc tank continuous immersion, the formation of a layer of zinc film on the metal surface, play a beautiful role in antirust!, the zinc layer is to protect the substrate from oxidation!

Hot dip galvanized: Zinc 40g/m2 regular spangle galvanized coils GI coils is divided into flower galvanized and no flower galvanized is zero zinc.
