Thanks for the help guys!
The panel will will have pem studs for mounting din rail and various components will mount via the din rail.
I will do a zinc/chromate finish. I will do more homework with this information.
What would the correct and cost effective process be for plating a sheet steel electrical panel? The panel has to conduct on all surfaces.
My local plater says "Zinc Plate with Blue Chromate" finish.
Any suggestions/experience?
