Shandong Fulilai Steel Group is a leading supplier of galvanized steel sheet & coil. Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. There are two main processes used to produce galvanized steel: continuous hot dipping and electro-galvanizing.
The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through electrolytic disposition. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer.
A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, but it will also sacrifice itself to protect the underlying steel sheet. Sacrificial or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel at areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.

| Type of surface |
After the hot-dip galvanized steel sheet is pulled out of the zinc pot, the appearance of the crystal grains formed as the zinc layer cools and solidifies is called spangles. The size, brightness and surface morphology of spangles depend on a series of factors, but they are mainly related to the composition of the zinc layer and the cooling method.Galvanized steel coil has the advantages of uniform coating, strong adhesion and long service life.
