Color coated steel coil is made of galvanized steel or galvanized steel substrate coated with different materials of paint,
so the grade of the substrate can refer to the hot-dip galvanized substrate.
The PPGI/PPGL rating determines its range of application: general purpose, stretch or deep stretch.
