Corrosion protection of sheet piles

Coating

The most commonly used form of corrosion protection for steel sheet piles is coating. On the basis of experience to date, it can delay the onset of corrosion by over 20 years.

To prevent harm to the environment due to blasting dust and overspray, steel components should be given the necessary corrosion protection in conformity with current regulations and recommendations if possible before installation. Since it is known that, given careful treatment, only minor damage occurs during transport and assembly, we recommend complete coating in the factory.

The choice of coating system depends on the anticipated stressing and the desired service life. We supply sheet piles with all conventional coating systems and give advice on the choice of system.

Because of the severe stressing to which sheet piling structures are exposed, epoxy resin or polyurethane coatings are usually applied. For the sake of the environment, only tar-substitute products and tar-free systems should be used.

Hot-dip galvanizing

Corrosion protection by hot-dip galvanizing is one of the widely used methods in steel construction. Combined with an additional coating (duplex system), synergies are created.

For the galvanizing of steel sheet piles a special steel analysis is necessary and compliance with regulations governing interlock tolerances. Surface quality and product identification must be taken into account. Notice should therefore be given of the intention to have the piles hot-dip galvanized before the start of rolling.
