The most common type of corrosion protection for steel sheet piles is coatings. To avoid environmental impact from steel dust and spray, steel components should receive the required corrosion protection in accordance with applicable regulations and recommendations prior to installation, if possible. To significantly reduce transport and installation damage, complete coating ex works is recommended.
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 terra interlock sealing system.
