Coil coating or pre-painting is an industrialized process in which large metal coils go through a series of fully automated production steps prior to final fabrication stages.
The process was born in the 1950’s. Since then, the fundamental benefits of painting “in the flat” and subsequently bending and cutting the material into shape have not changed.
Today, an estimated 80% of metal roofs and facades are painted by coil coating.
A fully in-house in process environment implies that no chemicals are directly released into the environment
Continuous process developments have led to heavy metal free production
98 percent of VOC's are eliminated by collecting VOC's from solvents and use of oxidizers to turn those compounds into fuel to for the ovens
Stable line speeds and flat surface application ensure an even paint distribution within a production batch
Line automation leads to optimum color stability between batches (important for large structure buildings)
The end products are green, too. Prepainted metal is fully recyclable, and coil coated products are often made of recycled content
The wide choice in available solutions offers an excellent color stability over building lifetime for every environment
Excellent corrosion resistance is assured by the strong combinations of conversion layers, primers and topcoats
Surface areas of over 500 sqm are economically ideal for coil coating applications; for smaller areas powder coating is often the right choice
Coated aluminum is a price economic alternative for anodized and painted zinc surfaces
