Heavy Duty GRP Anti-Slip Flooring, Grating & Treads

GRP (glass reinforced plastic) anti-slip flooring, also known as fibreglass flooring, gives a permanent, corrosion-resistant grip on walkways, stairs and platforms in the toughest site environments

What is GRP Flooring?

GRP flooring is made from glass reinforced plastic, a composite of glass fibres bound in a resin matrix. You'll also see it called fibreglass flooring, or glass reinforced polyester when a polyester resin is used. The result is a strong, rigid and lightweight material. A bonded grit surface gives it a permanent anti-slip finish.

GRP doesn't rust, rot or corrode. It stays safe underfoot in wet, oily and chemical-exposed environments where steel and timber degrade quickly. That's why it has become a standard choice for walkways, stairs, platforms and access routes across industry.

GRP vs steel and aluminium flooring

Steel and aluminium are still common in industrial flooring, but GRP has several practical advantages:

Corrosion resistance. GRP needs no galvanising or painting, and it won't rust in marine or chemical environments.
Lower weight. Panels are a fraction of the weight of steel, so they're easier to handle, install and replace, often without lifting equipment.
Non-conductive and non-magnetic. This makes GRP well suited to electrical installations, substations and rail environments.
Permanent grip. The gritted surface is part of the product, not a coating that wears away.
Easy to fit. GRP can be cut on site with standard power tools, with no welding required.

Choosing the right product

GRP grating. Grating is ideal for walkways, platforms, trench covers and mezzanines where liquids need to drain away. Our GRP Mini Mesh Grating has a small 19mm aperture, making it comfortable underfoot and safe for small dropped tools.
GRP stair treads. Anti-slip GRP stair treads fix over existing steps, including worn concrete, timber or chequer plate. They give full-depth grip without replacing the staircase.
GRP stair nosings. Anti-slip GRP stair nosings protect the leading edge of each step, where most slips start. High-visibility colours make step edges easier to see.
Decking strips. Anti-slip GRP decking strips are a cost-effective way to make timber decking, ramps and walkways safe in wet weather.
Step-over platforms. A GRP stepover platform gives safe access over pipes, cables and obstructions.

Applications

Offshore and marine: jetties, pontoons, rigs and vessels, where salt water destroys steel.
Water and wastewater treatment: walkways and covers exposed to constant moisture and chemicals.
Rail: non-conductive walkways, cable route covers and lineside access.
Rooftops: safe maintenance routes to plant and equipment.
Industrial plants: chemical, food processing and manufacturing sites where spills, oils and wash-downs make floors hazardous.

Installation and fixings

Correct fixing is as important as the flooring itself. We stock everything you need to complete the job in one order.

FAQs

Is GRP flooring slippery when wet?
No. The grit is bonded into the surface, so GRP keeps its grip in wet, icy and oily conditions.

How long does GRP flooring last?
Because it doesn't corrode or rot, GRP typically lasts much longer than untreated steel or timber in harsh environments, with minimal maintenance.

Can GRP stair treads be fitted over existing stairs?
Yes. Treads and nosings can be fixed over concrete, timber and metal steps using adhesive, screws or both.

Can I cut GRP to size on site?
Yes. Use a diamond or abrasive blade, wear dust protection, and seal the cut edges.
