MGDUFF is one of the foremost authorities on marine cathodic protection and one of the world’s leading suppliers of anodes for leisure boats, commercial ships and offshore structures.

Founded in 1956, MGDUFF was the UK’s first corrosion-control company and has pioneered the development of cathodic protection technology and anodes for yachts, powerboats, inland waterway vessels and commercial ships.

From trialling zinc anodes in Chichester harbour in the 1950s, MGDUFF, led by the Seabrook family, has grown over six decades to become a global expert in its field. As a result, MGDUFF is a byword for innovative engineering and high-quality anodes.

Today, with stockists all over the world, MGDUFF offers over 3,000 anodes and a bespoke anode manufacturing service, as well as a range of related civil engineering services.

Our foundry boasts energy-efficient electric furnaces and each melt is batch-tested using our computer-linked spectrometer to check chemical composition. This process ensures that each batch produces the high-quality anodes for which MGDUFF is known. We operate quality management systems that comply with ISO9001-2015, ISO45001-2018 and ISO14001-2015 requirements.
