The most commonly used method for galvanized steel coil is the hot-dip galvanizing process.
In the hot-dip galvanizing process, the carbon steel coil is immersed in an acid bath to remove the steel scale. Once the steel is cleaned and the scale is removed, it is continuously immersed in the molten zinc bath to form a metallurgical bond and protective coating with a controlled coating weight. The weight of the coating increases the corrosion resistance of the steel.
The zinc bath in the hot-dip galvanizing process contains trace elements such as aluminum. The presence of these traces optimizes coating adhesion and improves the ductility of galvanized steel, galvanized steel coils and galvanized steel slit coils, enabling the material to form hundreds of products that we use every day.
In previous steel making generations, galvanized steel coil used to contain large, flowery crystalline patterns of zinc on the surface of the steel known as "spangle". Spangle resembles large hexagonal snowflakes. Although today's galvanized steel still contains spangle, modern steel mills produce galvanized steel with spangle that is virtually undetectable to the naked eye. This is known as minimum spangle and zero spangle galvanized steel.
