Coil Coating Process

Cleaning & Pretreating

The cleaning and pretreating section of the coil coating process focuses on preparing the metal for painting. During the cleaning stage, dirt, debris, and oils are removed from the metal strip. From there, the metal enters the pretreatment section and/or a chemical coater whereby chemicals are applied to facilitate paint adhesion and enhance corrosion resistance.


In this stage a chemical that provides enhanced corrosion performance is applied. This treatment can be chrome free if required.
