ISO 12944

ISO 12944 is the international standard for corrosion protection of steel structures by protective paint systems. It defines how to design, prepare, apply and maintain coatings to ensure long-term durability in different environments.

Where is ISO 12944 applied?

This standard is widely used in:

• Oil & Gas – offshore risers, flare booms, topside piping.
• Petrochemical & Chemical plants – process vessels, reactors, insulated pipelines.
• Marine & Offshore wind – deck areas, turbine towers, hull details.
• Infrastructure & Power – bridges, cranes, boilers, turbines.

For you as an asset owner, ISO 12944 compliance ensures predictable coating lifetimes, reduced risk of premature failure, and lower lifecycle costs.

Extra explanation

ISO 12944 covers:

• Corrosivity categories (C1–C5, CX) – from mild indoor to offshore splash zone.
• Durability ranges – low, medium, high and very high (L, M, H, VH).
• Surface preparation requirements – typically Sa 2½ blasting.
• Coating systems – epoxy, polyurethane, zinc-rich, etc.
• Inspection & maintenance – to ensure ongoing protection.

It is one of the most cited standards in engineering specifications for industrial projects.

Pinovo and ISO 12944

Pinovo supports ISO 12944 compliance by:

• Delivering Sa 2½ blast cleanliness required for coating adhesion.
• Achieving consistent surface profiles in micron roughness.
• Enabling dust-free blasting in ATEX-classified zones.
• Preventing environmental contamination, aligning with sustainability clauses.

Pinovo does not apply coatings, but ensures your substrate is ready to meet ISO 12944 requirements.
