Galvanized coils are materials produced through a continuous hot-dip galvanizing process using hot-rolled steel strips or cold-rolled steel strips as the base plate. Hot-dip galvanized sheets are supplied as rectangular flat sheets after cross-cutting; hot-dip galvanized coils are supplied as rolls after being rolled.
