FRP MOULDED GRATINGS
& FOR WALKWAYS & INDUSTRIAL FLOORING
Manufactured by Plastic Fabricators
Metal grating in a chemical plant has a short shelf life. It rusts, it needs repainting, and worse, it has scrap value which means it occasionally walks off site. FRP molded grating was built to solve exactly this set of problems..
We manufacture FRP molded gratings in standard and heavy-duty load ratings, for walkways, platforms, trench covers, and solar farm walkways. No corrosion, no conductivity, no repainting, and because it's a composite material, no scrap value for anyone to steal.
TECHNICAL DATA
WHAT IS FRP MOLDED GRATING?
FRP molded grating is a load-bearing floor and walkway panel made from fibreglass and resin, moulded into an open mesh pattern instead of a solid sheet. It’s used wherever steel or GI grating would normally go walkways, platforms, trench covers, flooring — but without the corrosion, weight, or conductivity that comes with metal.
The grating is cast in one piece rather than assembled from welded bars, which is what gives it uniform strength across the whole panel and consistent slip resistance on the surface. Unlike pultruded grating, which is built from extruded profiles locked together, molded grating comes out of the mould as a single interlocked mesh — this is what gives it the higher load ratings needed for vehicle-rated flooring and heavy foot traffic areas.
In practical terms: if you’re standing on it in a chemical plant, walking across it on a cooling tower deck, or driving light equipment over it in a solar farm, molded grating is doing a job steel used to do — just without rusting, needing paint, or being worth stealing for scrap.

TYPES OF FRP GRATING WE MANUFACTURE
We manufacture two main profile families for cable tray applications: channel type (solid bottom) trays for lighter cable loads and enclosed protection, and ladder type trays for heavier cable bundles that need ventilation and easier access. All profiles are pultruded in Safety Yellow (RAL 1003) as standard; other colours are available on request for volume orders. Standard length is 6 metres, with custom cutting available.
FRP Moulded Grating
DESCRIPTION
FRP Moulded Grating is manufactured as a single, interlocked panel, creating a strong structure that distributes loads across both directions. Its open-grid design provides drainage and ventilation while reducing overall weight, making it a reliable alternative to steel for walkways, platforms, flooring, and access areas exposed to moisture or corrosive conditions.
WHY THE MOULDED CONSTRUCTION MATTERS
Because the load-bearing bars are formed together as one continuous panel, loads are shared across the grid rather than concentrated in one direction. This bi-directional strength helps the grating tolerate regular foot traffic, equipment loads, and occasional impact while maintaining stability, even after field cutting.
FEATURES
- Single-piece, interlocked moulded construction
- Bi-directional load distribution
- High strength-to-weight ratio
- Corrosion, moisture, and chemical resistant
- Slip-resistant walking surface
- Open mesh supports drainage and ventilation
- Non-conductive and low maintenance
- Easy to cut and install on-site.
APPLICATIONS
Industrial walkways | Access platforms | Mezzanine flooring | Trench covers | Drainage areas | Chemical plants | Water treatment facilities | Marine environments | Utility and maintenance platforms
FRP Pultruded Grating
DESCRIPTION
FRP Pultruded Grating is assembled from continuous pultruded bearing bars connected by cross rods to form a rigid grid. Unlike moulded grating, its primary strength runs along the bearing-bar direction, making it ideal for applications with predictable loads and clearly defined support spans.
WHY THE PULTRUDED CONSTRUCTION MATTERS
Continuous glass reinforcement gives the bearing bars high longitudinal strength and stiffness. When installed with the bars spanning between supports, the grating can handle longer spans and heavier directional loads with controlled deflection. Correct bar orientation is essential for safe performance.
FEATURES
- High strength and stiffness along the bearing-bar direction
- Excellent strength-to-weight ratio
- Suitable for longer, clearly supported spans
- Corrosion, moisture, and chemical resistant
- Slip-resistant walking surface
- Open grid supports drainage and ventilation
- Non-conductive and low maintenance
- Lightweight for easier handling and installation
APPLICATIONS
Industrial walkways | Access platforms | Catwalks | Stair treads | Trench covers | Mezzanine flooring | Chemical processing plants | Water treatment facilities | Marine environments | Utility platforms
FRP Grating with Chequered Plate
DESCRIPTION
FRP Grating with Chequered Plate combines a moulded FRP grating base with a solid, diamond-patterned top plate. It provides a closed, non-perforated walking surface while retaining the lightweight, corrosion-resistant, and non-conductive properties of FRP.
WHY THE CHEQUERED PLATE MATTERS
The solid top prevents tools, fasteners, liquids, and small components from falling through the grating. Its raised diamond pattern improves underfoot traction, while the moulded grating beneath provides structural support and distributes loads across the panel.
FEATURES
- Closed, non-perforated walking surface
- Raised chequered pattern for improved slip resistance
- Moulded grating base for structural support
- Helps prevent tools and small parts from falling through
- Corrosion, moisture, and chemical resistant
- Lightweight compared with metal flooring
- Non-conductive and low maintenance
- Suitable for indoor and outdoor installation
APPLICATIONS
Inspection platforms | Maintenance walkways | Mezzanine flooring | Equipment platforms | Work areas above machinery | Electrical facilities | Chemical processing plants | Water treatment facilities | Marine environments | Areas handling tools or small components

Standard Specifications
Universal grating size across all standard variants is 1220mm × 3660mm, with mesh box size of 38mm × 38mm. Load capacity is determined by panel thickness and rib thickness.
| Variant | Size | Mesh Box | Rib Thickness | Load Capacity |
|---|---|---|---|---|
| Standard (A) | 1220×3660×25mm | 38×38mm | 5/6mm | 500-600 kg |
| Medium Duty (B) | 1220×3660×30mm | 38×38mm | 5/6mm | 600-700 kg |
| Heavy Duty (C) | 1220×3660×38mm | 38×38mm | 5/7mm | 1000-2000 kg (with support; light vehicle movement only) |
Note: The heavy-duty 38mm variant is rated for vehicle movement only when installed with proper structural support underneath. It is not intended as a standalone vehicle-rated deck without support framing.

APPLICATIONS BY INDUSTRY
WHY THICKER GRATING CARRIES MORE LOAD
This is a common question, so here’s the straightforward version: load capacity in FRP grating comes from two things panel thickness and rib thickness — not the mesh size, which stays constant at 38×38mm across every variant.
Going from 25mm to 30mm to 38mm panel thickness increases the section depth of the grating, which is what resists bending under load. The rib thickness (5/6mm to 5/7mm) adds to this by stiffening the individual mesh members. That’s why the 38mm heavy-duty variant can handle up to 2000kg while the 25mm standard variant tops out around 600kg the mesh pattern is identical, but the structural depth carrying that load is very different.
This is also why the heavy-duty variant needs underlying support for vehicle movement at that load range, the grating panel alone isn’t meant to span unsupported the same way a lighter foot-traffic panel would.
