The coating that offers extremely good corrosion protection.

The new and exclusive WIROX coating from SPAX offers better corrosion protection in the neutral salt-spray fog test than is required by standard for conventional bright zinc coating and it has a considerably higher surface hardness. This makes it ideal for outdoor use in structures such as carports and pergolas, in which they are not directly exposed to the elements. What’s more, WIROX has a considerably higher surface hardness than, for example, conventional yellow zinc coating or zinc flake coatings, making it more resistant to mechanical stress.

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

  • WIROX provides far better corrosion protection compared with bright zinc plating (layer thickness: 4-6 µm under artificial atmospheric corrosion conditions)
  • WIROX is especially advantageous for service class 2 applications built to Eurocode 5 for outdoor structures without direct exposure to the weather, such as carports or pergolas
  • WIROX is chromium(VI)-free and therefore much more environmentally friendly both to manufacture and use than conventional coatings
  • WIROX is resistant to abrasion and mechanical stress
