PPGI Pre-Painted Colour Coated Coil (RAL)
Coil coated to EN 10169 / ASTM A755 over a galvanized substrate
PPGI is galvanized coil with a paint system applied on a continuous coating line: typically 15–25 µm of topcoat over 5–10 µm of primer and back coat. The substrate coating carries the corrosion performance; the paint carries the colour and the warranty. We supply RAL shades, PE, SMP, HDP and PVDF systems, matched to a colour sample or a RAL number.
