C4 EVO Coating
Rothoblaas coats the carbon steel screws in a 20 μm multilayer coating with a surface treatment of epoxy resin and aluminum flakes. There is no rust after 1440 hours of salt spray exposure, as per ISO 9227. This enables the screws to be used in service class 3 outdoor applications and under class C4 atmospheric corrosion conditions.
