Our advantages

Manufacturing scale.
Engineering judgement.

From conventional pressure pipe to 6-metre structured-wall systems, our capability is built around the realities of transport, installation and long-term operation.

Large-diameter manufacturing

Solid-wall PE pipe up to 1.6 m and project-specific spiral-wound structured-wall systems up to 6 m.

On-site pipe production

When oversized transport becomes a constraint, production equipment can be deployed to the project after feasibility review.

Standards participation

Technical experience includes participation in the drafting of national and industry standards.

Project-specific support

Diameter, pressure, stiffness, jointing and installation are reviewed against actual project conditions.
