In the ISO 12944 standard, which defines corrosion protection for steel structures using protective paint systems, the C5 Very High (C5-VH) classification refers to the most severe atmospheric corrosion environments – C5 – with the demand for a long durability – Very High / VH – of the coating system.
This table provides an overview of the most common coating systems tailored to different environments and expected durability levels. Some projects may require a more specific approach.
