Galvanized steel coil description

Galvanized steel is a carbon flat rolled steel product that is covered in a zinc coating on its surface. This coating increases a steel coil’s, slit coil’s, or sheet’s resistance to corrosion. The most common method of galvanizing steel is the hot dip galvanized process.
In the hot dipped galvanized process, base carbon steel coil is submerged in an acid bath to remove steel scale. Once the steel is cleaned and its scale is removed, it is continually submerged in bath of molten zinc forming a metallurgical bond and protective coating at a controlled coating weight. The coating weight immediately increases the corrosive resistance of the steel.
The zinc bath during the hot dipped galvanized process contains trace amounts of elements like aluminum. The presence of these trace amounts optimize coating adhesion and improve the malleability of galvanized steel sheet, galvanized steel coil, and galvanized steel slit coil allowing the material to be formed into hundreds of products that we use every day.
