Cullen Steel was established at Mascot, NSW in the 1930, making us one of the longest established steel fabrication companies in NSW. At the time, the principal activities included the fabrication of steel structures for the building industry and manufacture of agriculture equipment. During the Second World War, Cullen Steel was also involved in manufacturing armoured vehicles.
In 1946, Cullen Bros became a public company and relocated to an 8 acre site at Villawood, NSW. In 1959, Cullen Bros were taken over by Jaques Ltd and the company was subsequently renamed to Jaques Cullen. Jaques was a major supplier and exporter of equipment and plant for the mining, quarrying and construction industries, and as a result, the company expanded. The company not only continued to provide fabricated structural steel to the building industry, but also diversified into specialised fabrications for the mining and construction industries.
