History - A track record spanning 4 generations

The Sturrock and Robson journey began in 1912 when Frederick Claud Sturrock and Thomas William Robson ventured into business together.

The early businesses thrived during the South African mining boom of the 1920s and, under four generations of Robson custodians, have grown into a diversified, international group of industrial companies.

During the last century, we have gained invaluable experience, knowledge, relationships and a robust reputation – a reputation which continues to strengthen today.
