Galvanized  Coil

Galvanized Coil
Galvanized coils are products made of low-carbon steel, high-quality high-carbon steel, etc., through hot-dip galvanizing or electro-galvanizing processes. Hot-dip galvanized coils are made by immersing thin steel plates in molten zinc liquid to form an alloy layer and a pure zinc layer with the steel plate matrix. The zinc layer is thick and has strong adhesion and good corrosion resistance; electro-galvanized coils are made by electrochemically depositing a zinc layer on the surface of the steel plate, and the zinc layer is uniform and fine.
