The Composite Group develops agricultural and industrial fibreglass solutions, including specialist components, protective covers, equipment housings, storage tanks and more.
Below is a snapshot of some industrial products we have manufactured. Reach out if we can help build a bespoke product for your business.
Insulated and uninsulated Fibreglass Tanks
We manufacture purpose designed fibreglass tanks up to 100,000 litres for specialist processes, including beverages, winemaking, brewing, dairy, foodstuffs, industrial, pulp and paper applications, together with water and sewage systems.
ARC Over-Bridge Safety Screen
Our years of experience and innovative processes combined with design by Pollen Limited and composite engineering from Gurit developed 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 Overbridge Safety Screens were installed over an electrified rail track to prevent tampering with the lines from the overbridge.
Antarctic Laboratory
The Composite Group worked with Antarctica New Zealand to develop and then manufacture the internal fit-out of their new laboratory container that’s now located at Scott Base in Antarctica. The design was required to be watertight to prevent any moisture entering the laboratory, and fully insulated to withstand the -40 degree Celsius outside temperature.
The design includes insulated composite lined ceiling, wall and floor panels. Heating trace elements were fitted into the floor’s insulation panels, and around the pipe’s insulation cladding to prevent freezing. Shelf mounting brackets were moulded into the insulated walls to ensure the exterior steel cladding was not penetrated.

Trailers and Horse Floats
We manufacture fibreglass roofs for many of New Zealand’s top trailer box and horse float producers.
Heat Ranger Frost Fighting System
We created the moulds and the fibreglass body components for the Heat Ranger agricultural frost fighting system. The 5 metre high unit uses fan forced, heated air out though two rotating ducts to increase the temperature of the air below the inversion layer, to reduce the risk of a frost forming on low-growing crops, such as grapes or blueberries.
The Heat Ranger can cover most field shapes through its unique rotational air distribution management, and it is cost effective in both setup and operating costs per hectare covered. Heat Ranger is environmentally friendly, relatively quiet and very effective, giving it significant advantages over other frost management systems.
