Hot-dip galvanizing is the reaction of molten metal with an iron
substrate to produce an alloy layer, thereby combining the
substrate and the plating layer. Hot-dip galvanizing is to pickle
iron and steel parts first. In order to remove iron oxide on the
surface of iron and steel parts, after pickling, it is cleaned in
an ammonium chloride or zinc chloride aqueous solution or a mixed
solution of ammonium chloride and zinc chloride.And then sent to
the hot-dip plating bath. Hot-dip galvanizing has the advantages of
uniform coating, strong adhesion and long service life.

Galvalume steel is also called Aluminum-Zinc Alloy Coated
Steel,aluminized zinc steel(aluzinc steel),SGLC,The galvalume metal
is composed of 55% aluminium, 43.4% zinc and 1.6% silicon
solidified at 600 ~C. Its whole structure consists of
aluminium-iron-silicon-zinc, forming a compact quaternary crystal
alloy.The surface of the galvalume steel sheet is characterized by
smooth, flat and gorgeous stars, and its base color is silver
white. The special coating structure makes it have excellent
corrosion resistance.
The normal service life of galvalume steel sheet is up to 25a, and
its heat resistance is good. It can be used in high temperature
environment at 315 C. The adhesion between coating and paint film
is good, and it has good processing performance. It can be punched,
sheared and welded. The surface conductivity is very good.
