Protect surfaces that are highly prone to corrosion, rust and the detrimental effects of the environment which lead to weaker structures, reduced value of goods and gain a high cost of fixing. Our anti-corrosion solutions encompass both conventional and heavy-duty type coatings — ideal for any metal surface such as structural steel works, storage tanks (for edible products, fuel, oil water etc.), pipes, piles, vessels and metal bridges.
A Globally Recognised Standard For Corrosion Protection
ISO 12944 has the best practices in protecting structural steel surfaces. It all starts by ‘Selecting the environment’ and ‘Selecting the lifespan’ to pick out your desired durability.

ATMOSPHERIC-CORROSIVITY CATEGORIES AND EXAMPLES OF TYPICAL ENVIRONMENTS
Corrosivity Category | EXTERIOR | INTERIOR |
---|---|---|
C1 Very low |
- | Heated buildings with clean atmospheres, e.g. offices, shops, schools, hotels |
C2 low |
Atmospheres with low level of pollution: mostly rural areas |
Unheated buildings where condensation can occur, e.g. depots, sports halls |
C3 Medium |
Urban and industrial atmospheres, moderate sulfur dioxide pollution; coastal areas with low salinity | Production rooms with high humidity and some air pollution, e.g. food-processing plants, laundries, breweries, dairies |
C4 High |
Industrial areas and coastal areas with moderate salinity | Chemical plants, swimming pools, coastal ships and boatyards |
C5 Very High |
Industrial areas with high humidity and aggressive atmosphere and coastal areas with high salinity | Buildings or areas with almost permanentcondensation and with high pollution |
Cx Extreme |
Offshore areas with high salinity and industrial areas with extreme humidity and aggressive atmosphere and subtropical and tropical atmospheres | Industrial areas with extreme humidity and aggressive atmosphere |
Note: Corrosivity categories can also be estimated by considering the combined effect of the following environment factors: yearly time of wetness, yearly mean concentration of sulfur dioxide and yearly mean deposition of chloride (see ISO 9223). The loss values used for the corrosivity categories are identical to those given in ISO 9223.
CATEGORIES FOR WATER AND SOIL
Category | ENVIRONMENT | EXAMPLES OF ENVIRONMENT AND STRUCTURES |
---|---|---|
IM1 | Fresh water | River installations, hydro-electronic power plants |
IM2 | Sea or brackish water | Immersed structures without cathodic protection(e.g. harbour areas with structures like sluice gates, locks or jetties) |
IM3 | Soil | Buried tanks, steel piles, steel pipes |
IM4 | Sea or brackish water | Immersed structures with cathodic protection(e.g. offshore structures) |
Note: For corrosivity category IM1 and IM3, cathodic protection can be used with a paint system tested accordingly
Durability | YEARS TO FIRST MAJOR MAINTENANCE |
---|---|
Low (L) |
Up to 7 years |
Medium (m) |
7 to 15 years |
High (H) |
15 to 25 years |
Very high (VH) |
More than 25 years |
