Cathodic Protection of wharf structures is an effective method of corrosion protection. It increases the design life and can be replaced much more easily than reapplication of corrosion protection coatings. It is typically utilised in conjunction with corrosion coatings to form  a complete corrosion protection system. It is a sacrificial form of protection where an anode, typically made of aluminium or zinc alloy is bolted or welded to the steel structure.

The steel and anode material form a galvanic cell where the anode oxidizes preferentially to the steel, hence reducing or eliminating the rusting of the steel. ESC has the capability to design, supply, install and commission such cathodic protection systems.
