Our most commonly used mesh product. 38 x 38 mm (31 x 31 mm) aperture. Medium (general grade) grit surface.
Fibreglass Heavy Duty Mesh Grating
FRP (Fibre Reinforced Polymer), also commonly known as fibreglass, heavy duty mesh grating is ideal for applications that require additional load capacity. With a 50 mm thickness, it is suitable for drain covers, high-traffic areas, and loading bays in industrial and commercial applications. It is durable, low maintenance, easy to install, and provides resistance to slips and corrosion.
Safety and Quality Above the Standard
What Sets us Apart
We are a New Zealand family-owned and operated company with plenty of stock on-site from our premises in the Bay of Plenty. We provide an in-house cutting service, with our workshop fully equipped with sophisticated cutting processes and fabrication techniques. Non-standard sizes and finishes are available. Our team is always ready to provide technical support and design recommendations.
Our moulded FRP grating is manufactured using the hand lay-up and open mould casting process, combining strength, durability, and customisability in every panel.
How it Works:
Fibreglass reinforcements (roving or mat) are manually layered in both directions into a heated open mould (hand lay-up). Resin is then poured or brushed over the fibres (open mould casting) until fully saturated. The panel is cured in-mould, creating a solid, seamless structure with no joints or weak points.
Why This Process Matters:
Bidirectional Strength: Reinforcements are placed in both directions, giving equal load-bearing capacity across the panel.
Seamless, One-Piece Construction: No joints or welds – excellent durability and delamination resistance.
Customisable Resin System: Vinyl ester, polyester, or phenolic options are available, along with additives such as fire retardants, UV stabilisers, colour pigments, and anti-slip grit.
Ideal for Complex Mesh Designs: Allows for flexible mesh sizes, such as mini mesh and micro mesh.
Excellent Corrosion Resistance: Resin-rich surfaces provide high chemical and UV resistance.
Consistent Quality: The moulded surface ensures uniform bar spacing, thickness, and an anti-slip texture.
Efficient Production: Requires minimal finishing – only edge trimming and optional coating.
Load bar spacing: 38 x 38 mm (26 x 26 mm aperture)
50 mm depth
Dimensions: 3669(L) x 1230(W)
Non-standard sizes available.
Isophthalic polyester (ISO) – general purpose grade resin suitable for minimal contact with harsh chemicals
Vinyl Ester (VE) – superior grade resin formulated to withstand frequent contact with harsh chemicals
Medium Grit (600 µm | Approximately P40 to FEPA Classification): The trusted choice for general, commercial, and industrial use, providing reliable slip resistance in workshops, plants, and high-traffic areas.
Fine (barefoot friendly) and coarse (industrial) grit gradients are possible upon request.
