Our Approach

Our Values & Ethos

At DM Plastics & Steel, our values guide every decision—from the workshop to the worksite.


Clear decision-making, honest lead times, accountable delivery, and long-term relationships. These aren’t slogans — they’re how we operate every day on the floor and in the field.

Safety

No job is worth doing if it can’t be done safely. Safety is everyone’s responsibility, so we plan, train and operate with a zero-harm mindset and the discipline to stop work when something isn’t right.

Excellence

We work together to deliver the best outcomes. Collaboration, technical rigour and continuous improvement underpin the quality of our pipe and fittings, and the reliability our customers count on.

Integrity

We do the right thing and we do what we say we will do. Clear communication, honest lead times and accountable follow-through build trust on every project.

Respect

We embrace openness, trust and teamwork. We value diversity and build relationships that are mutually beneficial—within our team, with our partners and across the communities we serve.

About Us

Our Team

A “one-team” culture defines us — early issue escalation, open communication, accountability and technical expertise.

This mindset is why customers describe us as easy to deal with and why our partnerships last decades.

About Us

Our Facilities & Capability

DM Plastics & Steel operates from a 1.6-hectare site at Dry Creek, Adelaide. The location and layout give our customers real advantages: the greatest number of adaptable PE extrusion machines in South Australia to produce an extensive range of pipe classes, sizes and lengths; and production lines that combine state-of-the-art techniques with streamlined systems to meet order requirements efficiently.

We currently manufacture pipe and supply fittings from 16mm to 630mm in diameter.

This gives us one of SA’s most adaptable extrusion footprints.

About Us

Our team is active in PIPA, IAL, and CCF SA to stay aligned with industry best practice.
