About Us

CST Composites, or ‘Composite Spars and Tubes’ as it was originally known, was founded in 1995. From its inception the company has focused on the design and manufacture of cost effective, yet high quality, filament wound tubing to service marine, industrial and high-tech markets.

The strength of CST lies with its unique filament winding technology which has been developed and evolving since day one. Today the company runs four filament winding machines and three pultrusion machines giving a production capacity capability of more than 20 tonnes of composite per year. CST is the largest user of carbon tow in Australia and New Zealand. Our products are exported worldwide with significant markets in Europe, USA, China and Asia.

All of CST Composites’ profiles and tubing are manufactured at one of our two high-tech facilities in Sydney, Australia. With over 3000 sq. metres of floor space, our factories house a wide range of specialist machines and tools used for the fabrication of composite sections.

In the early days activities were focused in the marine market where CST worked closely with development classes such as the 18’ skiffs to produce carbon spars that were strong, responsive, light and reliable. Since then, the company has grown consistently year upon year, broadening its applications into the industrial and high-tech sectors.
