GRP Open Mesh Grating

GRP grating panels are lightweight, corrosion-resistant flooring panels made from Glass Reinforced Plastic. Designed as an alternative to traditional steel grating, open mesh GRP provides a durable, anti-slip surface for industrial walkways, platforms, access areas and other environments where safe and reliable flooring is required.

BM Steel stocks GRP flooring panels in a range of thicknesses, including 15mm, 25mm, 38mm and 50mm options, to suit different applications and structural requirements. The open mesh construction supports drainage and airflow, while the gritted surface provides additional grip in wet, oily or high-traffic environments. Panels can also be cut to size or shape according to project specifications.

GRP grating is particularly suited to walkway applications because it is lightweight, non-corrosive and non-conductive. A GRP walkway can therefore provide a practical solution in industrial, utility, marine and other demanding environments where exposure to moisture, chemicals or outdoor conditions can affect traditional steel flooring. BM Steel's open mesh grating is manufactured to meet relevant requirements of BS EN ISO 14122 for permanent means of access to machinery and BS 4592 for industrial flooring and stair treads. BM Steel

GRP grating load capacity depends on factors including panel thickness, the distance between supports, the type of load and the required level of deflection. Thicker panels can generally accommodate greater loads or wider spans, but the correct GRP grating panel should always be selected against the loading and support requirements of the individual installation. BM Steel provides load and deflection information for relevant products to support specification. BM Steel

Available in a variety of colours and thicknesses, BM Steel's GRP open mesh grating panels provide a hard-wearing, low-maintenance flooring solution for walkways, platforms, bridges and industrial access areas.

GRP Open Mesh Grating FAQs

What is open mesh flooring?

Open mesh flooring is a flooring or access surface made with regularly spaced openings rather than a solid panel. The open structure allows liquids, debris and air to pass through the surface, making it useful for industrial walkways, platforms and other access areas.

BM Steel's open mesh GRP flooring panels have a gritted anti-slip surface and are available in different panel thicknesses and colours to suit a range of environments and applications.

What thicknesses do GRP grating panels come in?

BM Steel offers GRP open mesh grating in 15mm, 25mm, 38mm and 50mm thicknesses. Different thicknesses suit different applications, spans and loading requirements, from lighter access areas to more demanding industrial walkways and platforms. BM Steel

The appropriate thickness should be selected according to the required load capacity, span between supports and specification of the project.

What is GRP grating?

GRP grating is an open mesh flooring product made from Glass Reinforced Plastic, also known as Glass Reinforced Polymer or fibreglass. It combines glass fibres with resin to create lightweight, durable panels suitable for flooring, walkways, platforms and access areas.

GRP grating panels are commonly used as an alternative to steel where corrosion resistance, low weight, anti-slip performance or electrical non-conductivity are important.

What is the load capacity of GRP grating?

GRP grating load capacity varies according to the thickness of the panel, the span between supports, the support arrangement and whether the load is concentrated or evenly distributed.

For example, BM Steel's 38mm open mesh GRP grating has published point-load and uniformly distributed-load deflection data across spans from 300mm to 1,500mm. This means GRP grating should not be assigned one universal load capacity; the required panel needs to be assessed against the expected load and span for the installation.

Is GRP grating suitable for walkways?

Yes. GRP grating is widely used for industrial walkways, access routes and platforms because it combines a gritted anti-slip surface with low weight, corrosion resistance and low maintenance requirements.

GRP walkway panels can be particularly useful in wet, exposed, chemical or marine environments where traditional steel flooring may be more susceptible to corrosion. BM Steel offers GRP panels that can be cut to suit the required walkway dimensions.

What are the advantages of GRP grating?

GRP grating offers several advantages for industrial flooring and walkway applications. It is lightweight, corrosion resistant, non-conductive and low maintenance, while a gritted surface provides additional slip resistance.

Unlike steel grating, GRP does not rust, which can make it particularly suitable for wet, outdoor, marine and chemically aggressive environments. Its lower weight can also make panels easier to handle and install.
