Moulded GRP Grating
Corrosion-Resistant GRP Grating Systems for Industrial Use
What Is Moulded GRP Grating?
Moulded GRP grating is manufactured as a single, integrated panel using a moulding process. Panels are produced in fixed sizes and can be cut on-site to suit specific installation areas, including penetrations, columns and irregular layouts.
The moulded structure provides uniform, bi-directional strength, allowing loads to be distributed evenly across the panel. This makes moulded GRP grating suitable for applications requiring flexibility in layout while maintaining resistance to corrosion, moisture and environmental exposure.
Characteristics of Moulded GRP Grating
Moulded GRP grating is designed for applications where durability, safety and environmental resistance are required.
Characteristics include:
- Bi-directional load-bearing capability
- Manufactured as fixed panels and cut on-site to suit installation requirements
- Excellent resistance to corrosion, chemicals and moisture
- Suitable for complex layouts and cut-outs
- Lightweight compared to traditional materials
- Minimal maintenance requirements
Moulded GRP grating is suitable for use in both internal and external environments where long-term performance is required.
Mesh Sizes
Moulded GRP grating is available in a range of mesh configurations to suit different safety and application requirements.
Standard Mesh Options
- Normal mesh – 38mm square
- Micromesh – 19mm square
Mesh selection is typically based on load requirements, foot traffic, equipment access and safety considerations.
Grating Thicknesses & Panel Sizes
Grating Thicknesses
Moulded GRP grating is available in a wide range of thicknesses to suit different load and span requirements:
- 13mm
- 25mm
- 30mm
- 38mm
- 50mm
- 75mm
Thickness selection is determined by load requirements, span, application conditions and compliance considerations.
Panel Sizes
Moulded GRP grating panels are manufactured in various metric and imperial sizes. Panels are supplied as fixed sizes and can be cut on-site to accommodate installation constraints, penetrations and irregular layouts.
Surface Finishes
Moulded GRP grating panels are supplied with integral surface finishes formed during the moulding process.
Meniscus Surface
A meniscus surface provides a slightly raised, concave finish formed during manufacture.
- Standard moulded finish
- Suitable for general industrial environments
Gritted Surface
A gritted surface finish provides enhanced slip resistance.
- Integral anti-slip finish
- Suitable for walkways, platforms and access areas
- Maintains slip resistance over the service life of the installation
Standards & Compliance
Moulded GRP grating systems are suitable for use in applications requiring compliance with recognised industry standards.
Moulded GRP grating supplied by PJNC is suitable for use in accordance with:
- BS 4592-6:2008 – Industrial flooring, stair treads and handrails manufactured from GRP materials
- BS EN ISO 14122 – Safety of machinery and permanent means of access to machinery
Typical Applications
Moulded GRP grating is used in applications where corrosion resistance, slip resistance and flexibility of layout are required. The bi-directional load-bearing structure and availability of different mesh sizes make moulded grating suitable for installations involving complex layouts, cut-outs and penetrations.
Typical applications include:
- Industrial walkways and access routes
- Platforms and service areas
- Water and wastewater treatment facilities
- Chemical processing and manufacturing plants
- Utilities and energy installations
- Marine, coastal and offshore environments
- Plant rooms and enclosed service areas
Moulded GRP grating is suitable for both new installations and refurbishment projects where durability, safety and minimal maintenance are required.
