High Quality PPGI (Prepainted Steel Coil) from Angang Steel, Shougang, HBIS and TPCO.
Prepainted Steel Coil Process
First, the steel coils are galvanized (Normally 55% Al +37%Zn + 8%Mg) to enhance their corrosion resistance. Then, they go through a surface preparation process, including cleaning, degreasing, and chemical treatment, to ensure good adhesion of the paint or polymer coating. Next, the coils are coated with paint or polymer in a controlled and uniform manner through rollers and coating application systems. After coating, additional curing or drying processes are carried out to ensure the proper adhesion and durability of the coating.
