Pre Painted Steel Coils

electro-galvanization employs an electric current to deposit dissolved zinc onto the surface of the material to be plated. This method offers uniform coating thickness and decorative properties, making it a preferred choice for various applications. However, unlike hot-dip galvanization, electro-galvanized materials typically undergo chromate treatment to enhance corrosion resistance and prevent white powdery corrosion formation.

PPGI Steel Coil

Commonly known as color-coated steel sheet, it is made of high quality cold-rolled steel sheet, hot-dip galvanized steel sheet or aluminium galvanized steel sheet as the substrate. After surface degreasing, phosphating and chromate treatment conversion, it is coated with organic paint and baked.
