What Avighna does with PPGI
How PPGI is made
Galvanised coil is chemically pretreated, then roller-coated and oven-baked in a continuous colour coating line.
- 1Pretreatment
Galvanised strip is cleaned and chemically converted so paint adheres permanently rather than sitting on the zinc.
- 2Primer coat & cure
A primer is roller-applied to both faces and cured in a hot-air oven.
- 3Top coat & bake
The finish coat is applied to the RAL shade and baked to a controlled peak metal temperature.
- 4Cooling & recoiling
Water quenching and recoiling follow; film thickness, gloss, adhesion and bend are tested per coil.
