Value Added Information and Considerations

  • Corrosion Zones Defined

  • ISO 12944-5:2019 is a part of the ISO 12944 series that deals with the classification of environments, design considerations, quality of materials, preparatory works, and application methods associated with the protective painting of steel structures. Specifically, ISO12944-5:2019 provides detailed guidelines on the types and uses of different protective paint systems. This standard aims to provide effective means of protecting metal structures, ensuring longevity, and mitigating risks from corrosion.

    Classification Of Environment
    ISO 12944-5 provides categories for different corrosivity environments (from low to very high) for varying degrees of corrosion risk. For instance, roofs in coastal areas will be exposed to a different set of conditions than roofs in inland environments. By identifying the environmental conditions that a metal roofing structure will be subjected to, appropriate protective measures can be taken.

  • Corrosion Zone

  • C1 - Heated buildings with clean atmospheres, e.g. offices, shops, schools, hotels - no interior corrosion, external conditions only.

  • C2 - Atmospheres with low levels of pollution. Mostly rural areas. Unheated buildings where condensation may occur, e.g., depots, and sports halls.

  • C3 - Rural, light to heavy industrial, and urban areas with pollution from nearby designated industries or small industries causing significant pollution. Also covers mild marine areas at least 1000m away from the marine environment, with a noticeable salt smell.

  • C4 - Covers heavy industries with high emissions, noticeable chemical odours (sulphur, acids), factories, and buildings with moderate humidity, prone to moderate corrosion due to technical and chemical conditions. Also extends to the marine environment within 100-300m inland from the shore.

  • C5 - Encompasses heavy industries/chemical sectors with strong emissions/odours (sulphur, acids). Addresses high to extremely high corrosion, including coastal buildings within 100m from the shore.

  • Case Histories

  • It’s only a matter of time for every metal roof to eventually have water ingress and for rust to take it’s toll. If you want to give owners the best protection at the best value, while saving time and money, you need to make one choice: the Alumanation 301 system. By selecting the Alumanation 301 system, you can offer the building owners a significantly less costly means of restoring their roofs compared to the enormous expense of roof replacement.
