Painting Galvanized Steel

thread332-31150

Painting Galvanized Steel

Painting Galvanized Steel

(OP)
We are looking to reduce cost on some parts and it has been suggested that we change from aluminum to galvanized steel on the chassis and covers of these parts.  I seem to remember that galvanized steel does not paint well.  Is this true? Is there a process to paint galvanized steel?

Thanks

RE: Painting Galvanized Steel

If you are trying to use steel for automotive underbody applications, you should use cathodic electrocoating - this is the standard process for the auto industry.

If you need an exposed part with matched paint, then you will need a multi-step system similar to what OEM's use to coat galvanized steel.

For either of these choices, try PPG Industries for more information:
