Leading National Galvanizers Proud to Be Chrome-Free

As part of our ongoing mission to become a truly sustainable business, we have successfully become completely Chromium Trioxide free.

After dedicating several years and significantly investing into the research, development and trials of alternative chemicals, Wedge Group Galvanizing Ltd is proud to have completely removed Chromium Trioxide from our processes – months ahead of the latest legislation set to govern this industry-wide.

David Nobes, Technical Services Director at Wedge Group Galvanizing Ltd, said: “Over the past few years in particular, we’ve made a conscious effort to reduce or remove high-risk and non-sustainable chemicals and metals from the galvanizing process – to ensure it’s safer for our team, compliant with legislation, and in line with our sustainability targets (and that of our customers too).

“With no direct equivalent to Chromium Trioxide available, it’s challenging for businesses – like ourselves – who want to not only adopt new procedures ahead of changing rules and regulations, but who want to also discover innovative, sustainable, and safer solutions.”

Chromium Trioxide is traditionally used in the passivation process during galvanizing. It creates a protective surface on the galvanizing coating that keeps the surface bright and shiny for up to 12 weeks, and minimises wet storage stain on the coating for the immediate period after galvanizing.

But as of September 2024, the European Union’s REACH legislation is banning the use of Chromium Trioxide in most manufacturing processes (including galvanizing). Due to this, the leading UK supplier will cease manufacture of the chemical ahead of this upcoming deadline.

David added: “This isn’t a new phenomenon to us and so we’ve luckily been unaffected by the regulation change. We’ve spent many years searching for an alternative solution, and one product in particular stood out to us as it works in a similar way alongside existing equipment and processes. Since 2020, we’ve been successfully trialling this non-chrome product at several of our plants, and it became common practice across all 14 at the end of April.

Wedge Group Galvanizing Ltd is the largest hot-dip galvanizing organisation in the UK with a history dating back over 150 years. With 14 plants strategically placed across the country, the firm offers a truly national galvanizing service.
