Protecting steel against corrosion

9 February 2023
How can we help you?

By coating or hot-dip galvanising steel parts, you can protect them against corrosion caused by oxygen, salt and moisture. That reduces the risk of a loss of stability in, or the failure of, a steel structure.

  • Applicable to utilities, factories and installations;
  • Spatial adaptation;
  • Permanent measure;
  • Substantial investment;
  • Prevents economic and environmental damage;
  • Applicable at flood depths up to approx. 50 cm.
Protecting steel against corrosion

Hot-dip galvanising involves coating steel with a zinc layer that protects the material against atmospheric factors. Coating also protects materials against salt water.

Complete conservation is very costly in areas where there are a lot of steel assets. In these circumstances, you may decide to protect the most vulnerable steel parts, those located in lower-lying areas or those that are difficult to replace.
