PPGI — Pre-painted Galvanised
Colour coated on a zinc (GI) base — the workhorse for roofing, cladding and appliances.
Overview
About PPGI
PPGI is galvanised steel coil that is cleaned, pre-treated, primed and finish-coated on our continuous colour coating line. The zinc layer protects the steel from rust while the paint gives colour, weather resistance and a clean finish. It is the most widely used colour coated steel in India for industrial roofing, wall cladding, pre-engineered buildings, sandwich panels, doors, shutters and white goods. We supply PPGI in coils, cut sheets, slit coils and ready profile sheets, in RAL-matched shades and a choice of paint systems for each climate.
