Salt spray hours | 29 March, 2010

I have a customer that wants 5000 hrs to red rust. The steel is plated with chloride zinc (barrel plated) and a black chromate. They say a company in Taiwan has the technology, but can not deliver in a production setting. Does anyone know of a cost effective coating over steel that can come close to that many SS hours?

5000 hours, yeow!!! Salt spray testing "periods range from a few hours (e.g. 8 or 24 hours of phosphated steel) to more than a month (e.g. 720 hours of zinc-nickel coatings, 1000 hours of certain zinc flake coatings)."

We have no relationship, nor receive benefit from the company referenced above.
