Power and data deserve protection from day one. DM Plastics and Steel manufactures durable polyethylene (PE) conduit and poly pipe systems for electrical and communications networks – ideal for subdivisions, rail, renewables, data infrastructure and brownfield upgrades. Engineered for clear visibility, easy identification and rapid installation, our conduits suit directional drilling, open trenching and other underground install methods, and integrate cleanly with water, gas and other utilities. Whether replacing cables or installing new sub-ducts for future network growth, DM Plastics and Steel delivers the right solution for your project.
High-visibility orange co-ex conduit for power cable protection in underground and trenchless applications.
White co-ex conduit for fibre, data and control cable protection across civil, telco and infrastructure projects.
Narrow-bore sub-ducts designed to run inside host ducts, organising and separating individual cable runs.
DMP&S non-pressure conduit solutions are engineered for the extreme demands of modern mining operations — long-distance runs, high UV exposure, elevated ambient temperatures and heavy site traffic. Available in coils and straight lengths, we offer bench or stage-based packaging, coordinated delivery scheduling and material specifications, compliant with site safety and asset-identification requirements, to keep power feeds, pit dewatering systems, comms corridors and plant services reliable and easy to manage.
For subdivisions, road and rail corridors, and precinct utility networks, speed, clarity and constructability are essential. Our conduit range is color-coded for unambiguous service identification (e.g., orange for electrical, white for communications) to streamline tie-ins and handover documentation. We advise on coil-versus-straight length deployment strategies tailored to your construction methodology, provide work-front packaging, and supply compatible PE mains for potable, recycled water, sewer and fire services so pits can be completed in a single pass.
Contractors delivering data centres, renewable energy sites and telco networks rely on smooth-bore conduit that facilitates efficient cable hauling and future expansions. Our products support long continuous pulls through directional drilling and other underground installation methods and integrate cleanly with water, gas and other utilities. Technical support covers bend-radius guidance and best handling practices to produce clean installations with fewer return visits. The result: reduced downtime, lower labour costs and systems ready for high-density cabling and future-proof upgrades.
DM Plastics & Steel supplies these products nationally. Standard coils are held in common sizes and lengths, with made-to-order options for projects and larger lengths available to streamline transport for large quantities. Talk to us for current lead times and logistics to your region.
With extensive experience supporting major infrastructure projects across Australia, DM Plastics & Steel specializes in non-pressure HDPE conduit pipe solutions. We provide informed material selection, site-optimised packaging (coils and straight lengths), and reliable supply tailored to conduit-specific installation methods. Our technical support covers sizing, bend-radius and handling guidance, accessory bundling and coordinated logistics to meet complex program schedules and on-site constraints. Guided by our motto, “Producing Solutions,” we deliver pragmatic, cost-effective conduit systems designed for durability, ease of installation and long-term performance.
Based at Dry Creek, Adelaide, DM Plastics and Steel is an Australian-owned manufacturer delivering locally made HDPE conduit and sub-duct solutions with flexible extrusion capacity across small to large diameters. Backed by ISO 9001 quality systems, in-house testing and R&D, we align production to live programs and stage deliveries so crews stay productive — reducing joints and downtime with continuous lengths on drums or coils, or straight lengths where appropriate.
Absolutely. We manufacture metric HDPE pressure pipe for water, gas and fire mains applications and supply compression, electrofusion, fabricated and moulded fittings, plus backing rings so you can source the full multi-utility package from one supplier.
Yes – we have extensive transport and rail experience, including the Gawler Rail Electrification Project (2020–2022). Our project delivery model aligns production with site programs, offering staged or workfront deliveries, just-in-time supply and coordinated logistics to keep crews productive and minimise downtime. Backed by ISO 9001, in-house testing and R&D, we co-engineer specials and manage documentation, inspections and handovers to meet programme, quality and safety requirements.
