How A Coated Coil Is Built

The finish is applied on the coating line, before the material ever reaches your press or your board bench.

Coil coating line sequence Uncoiler CleanDegrease TreatCr-free PrimerPolyester Top coatPrintPattern CureOven FilmPE film Recoiler Coil inCoil out

On PCM steel the printed pattern sits under a clear varnish and above the top coating, and a polyethylene film protects the face until the panel is installed. The full nine layer build up is published on every pattern steel product page.

Do you supply coil or cut sheet?

What is the difference between painted writing steel and ceramic writing steel?
