Plastic and polymer grating

Heavy-duty, customised and cost effective

Fire and corrosion resistant fibreglass reinforced plastic (FRP) grating is the superior alternative to timber and steel for safety rails, walkways, and jetty decking. Terra Firma is Australia’s leading FRP manufacturer, delivering high-performance, sustainable solutions across Australia.

70% lighter than steel

30-40% whole-of-life savings

20-25% faster to install than steel

Product of choice in over 500 projects Australia-wide

Timber rots. Steel corrodes.
Concrete crumbles.

For jetties, boardwalks, and public walkways, traditional materials carry a cost that doesn’t show up in the initial quote. Timber deteriorates in wet and marine environments, becoming a slip hazard and a maintenance burden. Steel corrodes in saltwater and coastal conditions, requiring repainting, recoating, and eventual replacement. Concrete cracks, creating ongoing repair costs and safety risks. The ongoing maintenance cycle costs more than the original installation – and creates real OH&S exposure every time it fails.

High performance
without the maintenance bill

FRP is what most people mean when they search for plastic grating – lightweight, non-corrosive, and built to perform in the environments where timber, concrete and steel struggle most.

  • No rust, rot, or corrosion – ever
  • Prefabricated offsite
  • Non-conductive – safe in marine, saltwater and industrial environments
  • Modular components cut on site – no hot works permits required
  • Fire resistant to BAL40
  • Lightweight and easy to install
  • Available in custom colours, grit and mesh sizes
  • P5 rated anti-slip surface
  • Colour stable – no repainting, no fading, no maintenance

Safe access in a corrosive marine environment, without the maintenance risk

SRG Global needed safe access to maintain and repair concrete supports beneath the Gladstone Wharf structure. Working in a confined, exposed marine environment, crews faced significant safety risks – traditional scaffold platforms couldn’t deliver the stability, slip resistance, and corrosion resistance the job demanded. Terra Firma supplied FRP Moulded Grating, giving crews a stable working platform that held up where traditional materials failed.

TerraGrate: Terra Firma’s full range of Australian-fabricated fibreglass reinforced plastic grating and products

Plastic Moulded Grating

Versatile open weave mesh for jetties, marine structures, and industrial walkways. Standard or custom panels, non-corrosive, lightweight, and stronger than steel mesh.

Plastic Pultruded Grating

High-strength bar construction for longer weight-bearing spans. Ideal for replacing aluminium and steel grating in corrosive marine and industrial environments.

FRP Solid Top Grating

Covered grating that prevents contamination below the surface. 50% higher stiffness than open mesh, suited to disability access ramps, food facilities, and wet areas.

Mini Mesh and Micro Mesh Grating

Composite walkway mesh for boardwalks, public walkways, and marine decking where airflow is required. Excellent slip resistance in wet, oily, and icy conditions.

Trench Deck

Anti-slip, interlocking, sealable flooring system. Chemical resistant and high tensile strength, suited to water treatment plants, public walkways, and civil infrastructure.

Stair Nosing and Stair Treads

Exceeds P5 per AS/NZS 4586:2013, customisable, high-visibility, suited to marine, industrial, and public applications.

FRP Structural Profiles

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

Anti-slip Sheeting

Surpasses P5 slip resistance, chemical, fire, and corrosion resistant, suited to high-traffic or wet areas.

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.”
