FRP mesh decking
and grating

their trust in Terra Firma

Timber rots. Aluminium bends.
Steel corrodes.

Traditional decking materials weren’t designed for Australia’s exposed environments. Timber deteriorates and becomes dangerously slippery in wet conditions. Chicken wire overlays distort and break down, creating trip hazards rather than preventing them. Steel corrodes in coastal and wet environments, increasing maintenance costs and liability exposure. For councils, asset managers, and contractors, the cycle of reactive repair and replacement is a budget and OH&S problem that compounds over time.

High performance
without the maintenance bill

Rigorously trialled and tested across Australia’s most demanding environments, TerraGrate mini mesh and micro mesh is the composite alternative to wood and steel that meets airflow requirements without compromising on slip resistance, fire safety, or durability.

Queens Park Lake Boardwalk Upgrade: 30-40% savings over the asset life

Moonee Valley City Council’s existing timber boardwalk and substructure had begun to rot, creating safety risks for pedestrians and increasing maintenance demands. Terra Firma delivered an engineered FRP solution using TerraGrate FRP Moulded Mini Mesh Decking and FRP Structural Profiles, replacing the decaying timber substructure with lightweight, corrosion-proof alternatives. The upgraded boardwalk provides a safe, durable, and low-maintenance access structure for community use, with installation completed with minimal disruption to the public.

Terra Firma’s TerraGrate range is designed for multiple applications and environments

FRP Moulded Mini Mesh

Open mesh composite decking for outdoor walkways, boardwalks, and industrial floors where airflow is required. Excellent slip resistance in wet, oily, and icy conditions.

FRP Micro Mesh

Finer mesh profile for applications requiring a denser surface, suited to shared pedestrian paths, public spaces, and environments where debris ingress or animal footing anxiety is a consideration.

FRP Mini Mesh Decking

Prefabricated decking panels in standard and custom sizes, ready to install with hand tools. Suitable for public spaces and bushfire zones.

FRP Structural Profiles

Channels, beams, angles, SHS, tubes, rods – outperform steel, timber, and aluminium for industrial, commercial, and marine applications.

TESTIMONIALS

Hear why
our customers
love Terra Firma

“Terra Firma pit lids substitute a poorly performing heavy product with a cost effective, strong, lightweight alternative. Their installation throughout the M80 upgrade has minimised the manual handling risk to workers by weighing ¼ of a concrete lid and through its easy to use lifting key that minimising the stress on the body whilst opening.”

VicRoads Innovations & Initiatives Bulletin

“The OH&S benefit for our maintenance workers, and the reduction in maintenance costs demonstrated during the initial trial installation has now led to the Council rolling out a budgeted annual pit lid replacement using lightweight composite lids.”

Engineer, Launceston City Council

“Frankston City Council have faith in the product and over the past 17 years have experienced the return on investment firsthand – in terms of economic benefits and time efficiency, as well as improvements to OH&S”

“We have seen Terra Firma continue to improve their lids from the word go – they have a lid for all situations, in classes B, C, D and E. They are well suited for practicality, as well as aesthetically with a selection of different colours enabling us to match the lid to the colour of the paving around it.”

Maintenance Planning & Contracts Coordinator, Frankston City Council

“The installation of the Bianco Precast encased Terra Firma lightweight pit lids at these locations have already paid forthemselves. Prior to these installations concrete pit lids were being replaced at these locations every month, sometimes twice a month. The Council has now begun specifying Terra Firma pit lids for capital works programs and new subdivisions.”

Civil & Maintenance Coordinator, City of Norwood Payneham & St Peters

“After discovering Terra Firma composite fibreglass lids, Unley City Council were able to reduce the number of workers required for installation and maintenance of their drain covers, as well as reducing the risk of injury to their workers”

Project Manager Capital Works, Unley City Council

“I can see a definite use for these lids as a replacement where needed – for pits around the City and Valley where the sweepers are causing deformation of the existing plastic lids. They would also be useful in other high traffic / vehicle path areas around existing intersections.”

Maintenance Coordinator, Brisbane City Council

“Don’t worry, with the Terra Firma D400 pit lids, we can open the lid, inspect the pit and have it closed before the customer has finished paying for their petrol.”
