// Product

Pit boxes and enclosures, made to order

We manufacture composite electrical pit boxes and enclosures for power, telecom and infrastructure networks.

Buried electrical assets need housings that do not rust, conduct or rot. Our composite pit boxes and enclosures are non-conductive, corrosion-proof and load-rated, made to your dimensions for cable pits, junctions and equipment.

Made to your dimensions

From standard pits to bespoke enclosures, we mould and fabricate to your size, load rating and fit-out, ready to install on the network.

// What we make

Boxes and enclosures

Pit boxes, lids and enclosures moulded and fabricated to suit the network.

Electrical Pit Boxes fiberglass
Cable pit boxes

In-ground pits for cable, power and comms networks, non-conductive and corrosion-proof for years in the ground.

Electrical pit boxes fiberglass
Equipment enclosures

Housings, cabinets and enclosures for field equipment, sealed against dust, water and the weather.

Electrical pit boxes fiberglass
Lids & covers

Load-rated lids and access covers engineered for footpath, light or heavy traffic, light enough to lift by hand.

Custom enclosures

Bespoke boxes built to your size, load rating and fit-out, with cut-outs, glands and fittings added in-house.

// Why composites

Why composite enclosures

Composite pit boxes do four things steel and concrete cannot.

Non-conductive

Electrically and thermally insulating, so buried assets stay isolated.

Corrosion-proof

No rust underground or in wet, dirty pits where metal breaks down.

Lightweight

Easy to handle, lift and install on site without cranes or heavy lifting gear.

Load-rated

Engineered and lid-rated for traffic, footfall and site loads.

// Materials & methods

The right material, the right process

Each box gets the laminate and lid rating matched to its load and location.

Materials

  • Fibreglass & GRP: tough, non-conductive, corrosion-proof.

  • Vinyl ester resin: extra chemical resistance.

  • UV-stable gelcoat: surfaces that last outdoors.

  • Load-rated lids: classes to suit traffic and footfall.

Processes

  • Moulding: boxes, lids and enclosures to shape.

  • Fabrication: cut-outs, glands and fittings added.

  • Custom sizing: built to your dimensions and rating.

  • In-house tooling: moulds and patterns held on site.

Common questions

In-ground cable pits, equipment enclosures, cabinets, load-rated lids and access covers, and custom boxes built to your size, load rating and fit-out.

Composite boxes are electrically non-conductive and corrosion-proof, so buried assets stay safe and isolated, and they will not rust underground or in wet, dirty pits the way steel and concrete do.

Yes. Lids and access covers are engineered and rated for footpath, light or heavy traffic to suit each location, while staying light enough to lift by hand.

Yes. We build to your size, load rating and fit-out, with cut-outs, glands and fittings added in-house.

All boxes are manufactured in-house at our facility in Wingfield, Adelaide. We are Australian owned and have operated since 1999.
