We have developed and manufactured a large array of transport products and solutions for vehicles as diverse as trucks, buses, motor homes, and even horse floats.

Designline’s award winning electrical bus

Fantastic shapes can be produced by liquid moulding techniques. This futuristic bus from Designline is a cutting edge low emission vehicle that is being trialled around the world. The concept and design is a credit to Designline and we are extremely proud to have been involved in the development of this state-of-the-art bus.

City bus parts

Our general moulding division manufactures components for Global Bus Ventures Ltd’s construction, offering a pattern making service, which constructs the plugs from which a mould is made. We also have a final assembly operation, where we fit mounting brackets and other hardware to complete each panel. The completed panels are then fitted to shipping jigs to protect them during transit and to ensure a perfect fit at the time of assembly.

Carbon Fibre components

Using a resin infusion process, we also make lightweight, strong components in carbon fibre, such as the internal ducting system for the interior of Real Journey’s coach. It not only looks good but is very light and strong. Any component that needs to be light and strong is ideally suited to carbon fibre construction. We supply external panels, roofs, dashboards, air conditioning, and heat ducting and a variety of other mouldings. These fibreglass panels reduce weight and assembly line labour.


Sandwich panels and insulated vehicle walls

We have developed machinery in our plant to enable us to manufacture sandwich panels up to 14m x 4m in size. Using a vacuum press we can custom build flat panels for any application.

Typical construction types are: Plywood core with fibreglass exterior surfaces (suitable for dry goods truck bodies, bulkhead, roofs, etc) a Polyurethane foam core with plywood stiffening and an exterior surface of high gloss fibreglass sheet.

These panels can be further reinforced with beams for roof application, door frames, hinge blocks, crush blocks etc. Foam-cored panels can be made for chiller bodies (0 degrees) or freezer bodies (down to -30 degrees).

The Composite Group has has also developed a process to foam insulate vans and finish the cargo space with a very durable and easy to maintain interior finish.

This process maximises the internal spaces by following the natural curve of the vans panels.

Fibreglass sheet supplies

The Composite Group is the New Zealand distributor for Vetroresina products and we can supply a range of fiberglass sheet on the roll or cut to length. The following options are available:

Thickness (mm) Widths (mm)
1.5 mm 2500,  3000
2.0 mm 2500
3.0 mm 2500,  3000

Available in lengths up to 60m, topside finish white gelcoat, bottom side is micro sanded. Other colours are available as special order.

Fibreglass sheet is typically used in the manufacturer of panels for the transport and motor home industries and specialist trailers such as horse floats.

The new aesthetic Vetrostyle products can be used for the manufacture of motor home and camper van interiors.

Enquiries for the Vetrorensina panel product are welcome.

Vetroresina fiberglass sheet wraps effortlessly around the sides of this trailer and is then finished with a custom made Composite Group roof.
Foam with fibre glass outside laminate and foam and plywood strengthened wall material.

Truck and van bodies and trailers

Although we don’t construct truck bodies, we do supply the components to make them, for example: roofs, and floor panels, doors and bulkheads, aluminium extrusion corner caps and interior light shells.

Many of our panels can be seen on the roads in the form of van bodies, trailers, and semi trailers.

Custom parts for the transport industry are also a specialty of our work, building bodies for special equipment trucks such as for a mobile water blast unit. This comprised a 2000 litre tank with flat sides (suitably strengthened) and a weatherproof, secure storage locker for the equipment.

Repair work and non slip surfacing

We undertake fibreglass repairs on your damaged truck body, and will happily do insurance quotes for this work.

We also offer a service, where we apply a non-slip surface to any truck van or trailer floor using Speedliner® – see more about Speedliner®.

ARC Over-bridge Safety Screen

Combine our years of experience and innovative processes with design by Pollen Limited and composite engineering from Gurit and the outcome is the ARC Over-bridge Safety Screen for electrified railways. The four interlocking components of the screens offer a practical solution to the overhead wire tampering issue. This robust product efficiently solves a problem and meets a need, while contributing a pleasing, colourful and dramatic aesthetic to the urban landscape.

The ARC Over-bridge Safety Screens installed over an electrified rail track to prevent tampering with the lines from the over bridge.


With our fibreglass manufacturing facilities and skilled staff we can repair your truck &/or trailer body, motorhome or caravan.

With our large vacuum panel table for manufacturing insulated body panels, we can also meet any specific panel needs you may have. We look forward to being of service to you. Request a meeting »
