40+ years supplying PE pipe, HDPE fittings, and irrigation systems across civil, mining, plumbing, irrigation, rural and electrical projects.
Send us your specs (DN size, pressure class, colour, quantity, SDR). We respond with transparent pricing and lead times — same day for standard SKUs.
Our team helps you choose the right SDR, PN class, joining method and coil strategy for long-term performance and on-site logistics.
Standard sizes don't always fit. We can co-extrude, custom-stripe, or assemble bespoke fittings to your exact specifications.
From quoting through commissioning, we're available to advise on constructability, safety, staging and site conditions.
Questions after delivery? Our team provides real-world advice on performance, maintenance and future upgrades.
We supply infrastructure across:
Rural poly pipe, fencing, Polpro risers and windmill hardware engineered for Australian farms, stations and pastoral operations.
Rural “B” LDPE, deliver end-to-end stock water and station solutions. ID-sized rural coils, metric PE (potable and recycled water), compression fittings and LDPE options (black, lilac co-ex, white co-ex) support efficient irrigation network builds.
End-to-end vineyard solutions combining metric/rural HDPE mains and LDPE laterals with our specialist accessories: Steel Vinstakes & extension posts, Prudent™ trellis clip system, poly wire-ties, bird-net caps and supports. Designed for long service life, UV stability and quick installation across new plantings and renewals, with valves and fittings to suit block layouts and pump configurations.
Metric PE families (potable, sewer, recycled water, fire mains) and non-pressure conduit for trench/open-cut and trenchless programs; full fittings suite for constructability.
Metric PE including plain black and white co-ex for dewatering, process water and trunklines, with fabricated fittings and backing rings for site assemblies.
Metric PE (blue/black), yellow stripe for gas, cream stripe for sewer and red stripe for fire main applications, with compression/electrofusion fittings and QA support.
Orange co-ex electrical, white co-ex communications and sub-duct HDPE conduit for cable protection in linear and urban works.

HDPE is our high-density pressure pipe for potable water, sewer and industrial applications. LDPE (low-density polyethylene) is more flexible, used for rural and agricultural systems. HDPE (high-density polyethylene) covers both, with superior durability for harsh conditions. We’ll help you pick the right grade for your project.
SDR (Standard Dimension Ratio) controls pressure rating and wall thickness. PN (Pressure Nominal) is the working pressure class (e.g., PN10, PN16, PN20). We’ll recommend the right combination for your application.
Absolutely. We have in-house R&D and co-extrusion capability. Common custom options include colour-striping (for identification) or white co-extrusion (for UV protection in rural applications). Ask us.
Yes. We’re ISO 9001 accredited, ISO Type 5 certified, WaterMark certified, SA Water approved, and hold a WSAA appraisal. Every metre is tested on-site to Australian standards.
