Pre-painted galvalum steel coil/sheet or PPGL is based on galvalume steel coils/sheet and features: excellent aesthetic appeal, formability, corrosion resistance, strong adhesion and longer service time.

PPGL is pre-painted galvalume steel, also known as Aluzinc steel. The galvalume & aluzinc steel coil uses the cold-rolled steel sheet as a substrate and solidified by 55% aluminum, 43.4% zinc and 1.6% silicon at 600 °C. It combines the physical protection and high durability of aluminum and the electrochemical protection of zinc. It is also called aluzinc steel coil.
