Capabilities
Tough plastics fabrication, engineered end-to-end from our Jandakot workshop since 1999. Design and engineering, in-house CNC and welded fabrication, and a deep HDPE stock — all under one roof.
What we do
Polyline holds Air, Water and People capability under a single roof in Jandakot — so design, engineering and fabrication never travel between vendors.
CNC-cut, butt-welded and extrusion-welded HDPE ducting that survives the mine. Straight runs, 45/60/90° elbows, branches, T-pieces, flanged bag adapters — engineered to reduce friction, leakage and recirculation.
See productsPump floats, modular pontoons and floating intake screens — CFD-modelled, FEA-verified at every lifting point. Donut floats in small/medium/large; pontoons that ship under 2.7 m width for road transport.
See productsFlat-pack escapeways assembled on-site with full installation documentation. Cable stoppers, hose hangers, vehicle protection — engineered HDPE for the parts of the mine where people work.

Every Polyline build starts in SolidWorks, gets stress-tested in FEA, and — when airflow matters — runs through CFD before the first weld is laid.
One-off and custom HDPE products fabricated to your drawings — for mining, civil, industrial and marine.

Polyline holds standing stock of UV-stable Simona HDPE in PE100 black, natural-white and hi-vis yellow — sheets, rolls and bar — ready to feed our CNC, butt-welding and sheet-bending lines.

HDPE versus steel for buoyancy and structural pontoon applications: lower density, immune to corrosion, no painting, lower lifecycle cost, ~55–80% lower carbon footprint at equal buoyancy.
