PPGL — Pre-painted Galvalume
Colour coated on an aluminium-zinc (GL) base for longer life in coastal and harsh weather.
Overview
About PPGL
PPGL is colour coated on galvalume — a 55% aluminium, 43.4% zinc, 1.6% silicon alloy coating. The aluminium gives a barrier against corrosion and heat, so PPGL typically lasts much longer than PPGI in coastal, humid and industrial air. It is the preferred choice for long-life roofing, factory buildings, warehouses and cold chain facilities. We coat PPGL on the same line with the same paint systems and supply it in coils, sheets and profiles.
