Galvanized coils are divided into galvanized coils with spangle and galvanized coils without spangle. Galvanized coil with spangle The galvanized coil with spangle is a zinc flower obtained by condensing the zinc layer under normal conditions after galvanizing. It is mainly used for general purposes. The galvanized with spangle are also divided into small spangle, medium spangle and big spangle, which are mainly used in construction and other occasions with less direct contact with the human body.
Galvanized coil without spangle The Galvanized coil without spangle mainly refers to a special production process, which generally controls the lead in the zinc pot to a certain level.
