GRP grating stair treads deliver a permanent anti-slip solution for industrial and commercial staircases, replacing painted steel and chequer plate that quickly loses grip in wet, oily or chemical environments. The integral grit top surface bonds the slip resistance into the panel itself, so it cannot wear off, peel away or be missed in a maintenance cycle.
Specified across food production, water treatment, offshore, rail and chemical processing sites, GRP stair treads are corrosion-resistant, lightweight and supplied with a bonded contrasting nosing that marks the step edge. They fit onto angle supports fixed to the stair stringers and are held down with M clips, for new staircases and refurbishment projects alike. Grating stair treads come in packs of two in 617 x 310mm, 725 x 310mm and 966 x 310mm sizes. Please allow 3 to 4 working days for delivery of these treads. Bespoke cuts available on request.

GRP stair treads: specification guide
GRP grating stair treads are complete fibreglass treads with an integral anti-slip grit surface and a bonded contrasting nosing. They are fitted as the treads themselves on new or refurbished steel staircases, onto angle supports fixed to the stair stringers. Where existing steps are sound but worn or slippery, our GRP stair tread covers fit over them instead. Because GRP will not rust and grips in the wet, fibreglass stair treads are the usual specification for external staircases, fire escapes and industrial stairs.

Treads, tread covers or nosings?
Choose full grating treads when you are building or re-treading a steel staircase, tread covers when the existing steps are structurally sound but worn or slippery, and nosings when the steps are in good condition and you only need to upgrade grip and edge visibility. Grating stair treads have a bonded contrasting nosing, and tread covers come in black and white, black and yellow, grey and yellow or all stone.
Fitting GRP stair treads
GRP grating stair treads fit onto angle supports fixed to the stair stringers and are held down with M clips, and tread covers fix over existing steps with a simple glue and screw fixing, with no hot works needed. Treads can be trimmed to width on site with a diamond blade and dust extraction, as shown in our cutting guide, or cut to size by us. For the surrounding structure our open mesh grating covers landings and walkways, and GRP platforms and step units handle access over plant and pipework.
Where GRP stair treads are used
External staircases and fire escapes, plant room and mezzanine stairs, marine and offshore installations, rail and transport sites and anywhere steps get wet, oily or icy. The combination of grit surface and contrasting nosing tackles the two main causes of stair accidents: slips and misjudged edges.

Frequently asked questions
What are GRP stair treads?
They are fibreglass stair treads made from 38mm GRP grating, with an anti-slip grit surface and a bonded contrasting nosing on the leading edge. They fit onto angle supports fixed to the stair stringers of steel staircases and are held down with M clips. To make worn steps safe again, GRP stair tread covers fit over the existing steps instead.
Can I fit GRP treads over my existing steps?
Yes. If the existing steps are sound, GRP stair tread covers fix straight over concrete, steel or timber steps with a simple glue and screw fixing. Full grating treads are for open steel stringers and new staircases.
Are GRP stair treads slippery when wet?
No. The bonded anti-slip grit surface is designed for wet and greasy conditions, which is why GRP treads are the standard fix for external stairs and fire escapes that get slippery in the rain.
Why do the treads have a contrasting nosing?
The contrasting nosing makes the step edge easy to see, which reduces trips and missed steps and supports the visibility guidance for stairs in workplaces and public buildings.
Can stair treads be cut to width?
Yes. Treads can be trimmed to your stair width on site with a diamond blade and dust extraction, following our cutting guide, or ask us about cutting before delivery.
How are GRP stair treads fixed?
GRP grating stair treads fit onto angle supports fixed to the stair stringers and are held down with M clips, and tread covers fix over existing steps with a simple glue and screw fixing. No welding or hot works permits are needed.
How many treads come in a pack?
Our 38mm GRP grating stair treads are supplied in packs of two, with trade prices shown on the product page.
Are GRP stair treads fire rated?
They are made with a fire retardant ISO resin system with fire performance to BS476. Our guide Is GRP grating fire resistant? explains the ratings.
Do you deliver stair treads next day?
Tread covers and nosings ordered by 12pm are normally dispatched the same working day. Please allow 3 to 4 working days for GRP grating stair treads. You can request a sample before ordering a full staircase.
