C4 introduces serious corrosion risk. A bare steel panel exposed to C4 will show visible rust within months. Coatings require 2–3 layers: zinc-rich epoxy primer (100–150 µm), epoxy intermediate (100–150 µm), polyurethane topcoat. ISO 12944 helps engineers select a protective coating system by defining atmospheric corrosivity categories (C1 to C5 and CX) and linking the environment + durability target to coating system performance expectations. If your project spec says “C3/C4/C5,” it's essentially telling you how aggressive. Selecting the appropriate steel for use in a corrosive environment classified as C4 (according to ISO 9223) is crucial. This system is used across many manufacturing and construction industries to enable a common language of corrosion environments to which each industry can adapt their. The C4 classification system is part of the ISO 12944 standard, which offers comprehensive guidelines for assessing the corrosion protection needs of steel structures exposed to diverse atmospheric conditions. Like other classifications in this standard, C4 designates a specific level of.
