Appliance Grade Deep Drawing PPGI Steel Coil – Zero Spangle
Product Overview
Appliance-grade pre-painted galvanized steel (PPGI) is a high-precision color coated product specially developed for home appliance manufacturing. Built on zero-spangle deep-drawing galvanized steel substrate with appliance-grade polyester paint, this DC04 grade delivers ultra-smooth surface appearance, excellent deep formability and consistent paint adhesion. It is the standard material for home appliance shells, panels and internal components, and is widely adopted by global home appliance OEMs.
