Successful corrosion protection. Stable, durable, safe.

Three forms of corrosion protection are available to enhance the durability of sheet piling – and hence increase the chances of success for your project: coating, hot-dip galvanizing and cathodic corrosion protection

The choice of coating system depends on the corrosion loads expected and the design life (see also DIN EN ISO 12944). Owing to the high loads to which steel sheet piling is usually exposed, epoxy resin or polyurethane coatings are normally used. Such coatings are also compatible with the tk interlock sealing system.

Hot-dip galvanizing

Hot-dip galvanizing is another method of corrosion protection and is also compatible with the tk interlock sealing system. It can also be combined with a coating (duplex system) to yield additional benefits. The requirements of DIN EN ISO 1461 must be adhered to.

Cathodic corrosion protection

Corrosion of steel sheet piling below the waterline can be largely eliminated by the use of cathodic corrosion protection. This is particularly recommended in areas where renewing protective coatings or repairing corrosion damage is technically very difficult. These areas must be taken into account in planning.
