Poly Welding

Delivering quality work throughout Queensland and PNG

DSM Poly specialises in the installation of poly pipe, electro-fusion and extruder welding and fabrication. 

With over twenty years experience, we have gained a reputation for delivering excellent workmanship, with a proven ability to tackle the most difficult and demanding projects.

Who we are? 

DSM Poly was founded in 1994 by Dieter Sanger. Since inception DSM Poly has developed into a well-known company throughout the Queensland and Papua New Guinea Mining industry. In 2017 Dieter Sanger retired, retaining ownership with new management succession to Sam Livingston a loyal 12 year employee of DSM Poly welding. Sam Livingston accepted the Director role in 2017 priding himself on the same visions and values within the business.

We are committed to providing a safe and diverse workplace.  65% of our workforce are Indigenous traditional land owners of the Gudjal and Kalkadoon peoples.  At DSM Poly we are committed to providing  equal rights and opportunities for all workers, regardless of gender, colour, age, ethnicity, physical ability, sexual orientation and religious beliefs.

We pride ourselves on our high standard of work, safety, loyalty and honesty. We work closely with our clients to ensure they get the quality and high standard of work they deserve. Some of our major clients include Civil and Mining Industries throughout Queensland and Papua New Guinea.

Recycling forms a vital part of who we are and we recycle all our PP and PE shavings. DSM Poly has also installed a 10 kilowatt solar system that supplies enough power to our premises, thereby minimising our carbon footprint.
