HDPE FABRICATION · WA SINCE 1999

Tough plastics. Tougher jobs.

Engineered HDPE that keeps air, water and people moving — safely. Designed, analysed and fabricated for the industry.

What we do

Air. Water. People.

Three product pillars built for a single environment — the working mine.

Air

Mine ventilation ducting

Rigid and segmented HDPE ducting for positive and negative pressures. Straights, Elbows, Y-pieces, branches and adapters — custom sizes and custom shapes.

How we work

Design. Analyse. Fabricate.

More than fabrication — we engineer the solution.

01

Design

3D concepts, layouts and visualisations. R&D on project-specific innovations.

02

Analyse

FEA analysis. Computational Fluid Dynamics where airflow or intake behaviour matters.

03

Fabricate

CNC routing (4100 × 2055 mm bed), fusion butt-welding and DVS 2207-4 extrusion welding — all under supervision.

§03

Cases in the field

Shipped. On-site. Working.

Did you know

A single 110 kW mine fan costs around $400,000 a year to run. Reducing friction, leakage and recirculation directly impacts cost.
