Tough, but still good to the environment.
YELLOX is chromium(VI)-free.

YELLOX is free from chromium(VI) and therefore environment-friendlier than standard yellow zinc coating – both during manufacture and in use. Despite this, it’s also more resistant to corrosion than the conventional bright or yellow zinc coatings used for screws. YELLOX is an innovation that benefits the environment and the user.

Listed below are the advantages and characteristics of the globally unique YELLOX coating from SPAX at a glance:

  • YELLOX gives you 6 times better corrosion protection compared with bright zinc coating of the same thickness (coating thickness of 4–6 μm under artificial atmospheric corrosion conditions).
  • YELLOX is chromium(VI)-free and therefore much more environmentally friendly both to manufacture and use than conventional coatings.
  • With YELLOX, the screw retains its yellow finish, offers greater corrosion protection and is chromium(VI)-free
    (i.e. environment- and health-friendly).
