Widnes Galvanising, the latest addition to the Joseph Ash Group, has just launched their new environmentally-friendly passivation process!
An alternative to hexavalent chrome passivation, Widnes Galvanising’s non-chrome 6 passivation is a fantastic step towards keeping the galvanizing process environmentally friendly, as well as making sure we deliver only the best quality finish for our customers.
After hot dip galvanizing has taken place, items (on request) are “passivated”. Passivation causes a chemical reaction to occur, where a thin transparent layer of metal oxide coats the galvanized steel to help reduce the effects of wet storage stain and cool the items so they can be handled safely.
Our new passivation process does not use hexavalent chromium (Cr(VI)) compounds within the process. Instead, it relies on compounds which are considered less toxic and more environmentally friendly. Our new method of passivating is a safer alternative to traditional Cr(VI) passivation, while delivering only the highest-quality finish for our customers.
The main difference between hexavalent chrome passivation and our new non-chrome 6 passivation is its environmental impact; Widnes Galvanising’s passivation process is more environmentally-friendly than traditional Cr(VI) passivation. At Joseph Ash we’re dedicated to protecting the environment, so this is a fantastic change for our Widnes site.
