The right grate goes a long way

Terra Firma TerraGrate is Australia’s leading manufacturer and supplier of fibreglass reinforced polymer (FRP) & glass reinforced plastic (GRP) grating and mesh.

Our Australian-fabricated FRP and GRP grating significantly reduces your costs thanks to its lighter weight, higher durability, and greater design flexibility.

Our FRP & GRP products can be used in anti-slippery floors, walkways/footpaths, operation platforms, docks, ramps, trench covers, and even stairs. Having supplied grating to some of Australia’s largest companies, we’ve proven that FRP grating is superior to steel and aluminium grating.

Cost-effective grating that meets
all your needs

Our FRP grating is available in a variety of resins, standard and custom colours, depths, panel sizes and mesh
configurations. We also offer structural pultruded profiles.

FRP Moulded Grating

Versatile open weave mesh in various sizes, depths, resins, and colours offers a lighter, stronger, and more durable alternative to traditional materials. Available in a variety of standard panel sizes, or can be manufactured as custom panels ready for installation.

FRP Pultruded Grating

Made from a matrix of high-strength pultruded bars, and is ideal for replacing aluminium and steel grating in corrosive environments. Designed for use where longer, stronger, weight-bearing support spans are required.

FRP Solid Top Grating

Terra Firma Solid Top Grating is covered grating that prevent contamination below the surface. It’s reinforced with glass fibre plates applied to one or both bearing surfaces, providing 50% higher stiffness than that of open mesh gratings.

Mini Mesh and Micro Mesh

Specifically designed for outdoor walkways, industrial applications or where solid flooring is not permitted due to airflow requirements. Mini Mesh provides excellent slip-resistance in wet, oily, and icy conditions.

Trench Deck

Trench Deck is an anti-slip, interlocking, sealable flooring system. Suitable for public walkways and civil infrastructure, such as WTPs, due to it’s chemical resistance, high tensile strength, cost-effective, and sustainable benefits.

Grating Clip Systems

Made from 316 grade stainless steel, Terra Firma Grating Clip Systems are available in a wide range of fixing options. Talk to the Terra Firma team for recommendations for your project.

FRP Structural Profiles

Suitable for use in industrial, commercial and marine applications, our Structural Profiles outperform steel, wood and aluminium for safety and strength. Profiles include channels, beams, angles, SHS, tubes, rods, embedment angles and plates.

Anti-slip Sheeting

Anti-slip sheeting offers resistance to chemicals, fire, and corrosion, reducing slip hazards in high-traffic or wet areas. Designed to surpass P5 slip resistance rating, these customisable plates fit any floor size, ensuring safety in various environments.

Stair Nosing

Customisable high-visibility, anti-slip stair nosing suitable for any step size. Durable for high-traffic, wet areas in marine, industrial, commercial, and public spaces. Non-slip surface exceeds P5 rating per AS/NZS 4586:2013 standard for pedestrian materials.

Plastic Pedestals for FRP

Durable pedestals, crafted from UV-stable, recyclable polypropylene, are strong, lightweight, and reusable. Heights range from 12.5mm to 1460mm, with versatile accessories like slope adjusters, wall fixings, and stabilising rods for various applications.

FRP Rebar

FRP Rebar can be manufactured to unique standards and is the product of choice where specific performance characteristics are required. Offering a lightweight, robust, and durable alternative to traditional steel reinforcement for concrete and masonry structures.

Cable Trays

Durable cable trays, chemical/corrosive/fire resistant, outpeforming metal alternatives. Ideal for hostile environments—oil rigs, electric and chemical plants, refineries. Lightweight, easy install, excellent thermal/electrical insulation, radio wave transparency.

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.”
