Den Tucker and Martin Brocklesby - the names behind the D and M - started DM Plastics & Steel more than 30 years ago and while Martin moved on in the 1990s, the business name remains and continues to grow. The South Australian company manufactures and exports a variety of plastic and steel products for the rural, mining, viticulture and civil sectors.

DM Plastics & Steel, based at Dry Creek in Adelaide’s northern suburbs, is a major Australian manufacturer - and the only South Australian manufacturer - of polyethylene pipe, used for water movement for stock, mining, domestic projects and major water infrastructure.

The company also manufactures a range of innovative products for fencing, vineyards and roadside safety, including the guideposts, sign posts and buffer rails we drive by every day on our metropolitan and regional roads.

The focus is “producing solutions” for its clients – everything from vinstakes for vine growers to polydroppers for fencing.

DM Plastics continues to grow with more than 50 staff and a 2,500-strong distribution network across the country and overseas. Its fencing products are exported as far as Hong Kong, the Falkland Islands and the Middle East.
