Whether in the atmosphere, water or soil, all unprotected steel is subject to corrosion which will eventually lead to failure. To avoid this, steel should be protected not only from the service environment but also for the proposed lifetime of a structure. 

The ISO 12944 standard is designed as a guideline for architects, engineers, specifiers, contractors and applicators in choosing the correct systems to meet the demands of both environment and service life. 

Choosing a coating system that complies with ISO 12944 can be achieved in three straightforward steps. 

With vast experience and expertise globally in protecting on & offshore structures for all concepts of the protective market, Jotun has a coating system to meet the exact anticorrosive requirements for every situation.
