Electrical & Comms FAQs

What's the difference between orange and white conduit?
Use orange for electrical circuits and white for communications/control. Clear colour separation reduces errors during installation and future maintenance.
Yes – where handling and bending radii permit, coils decrease the number of joins and reduce installation time.

Yes – our range of HDPE electrical and communication pipe is manufactured to the same dimensional standards as AS/NZS:4130. We also produce metric PE pipe 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 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. Custom continuous coil lengths are also available, subject to feasibility and MOQs.
