Open Mesh GRP Stair Tread Grating FAQs

What makes GRP stair tread gratings safer than steel alternatives?

GRP treads offer a gritted anti-slip surface with a high-visibility nosing strip, maintaining traction even in wet or oily conditions. Unlike steel, GRP remains non-slip without surface wear or rusting. 

Are these stair treads suitable for outdoor environments?

Yes. The corrosion-resistant GRP construction performs well in coastal, chemical, and high-humidity environments without degradation or surface damage. 

Can GRP stair treads be retrofitted onto existing stairs?

Yes. They can be installed onto existing steel or concrete frameworks using mechanical fixings, providing an effective upgrade to improve safety and durability. 

Do these gratings comply with UK safety standards?

All BM Steel GRP stair treads are designed and tested in accordance with BS EN ISO 14122 and BS 7976-2 for slip resistance, ensuring compliance with workplace safety requirements.

Are custom sizes or colours available?

BM Steel can supply stair treads cut to specification, including bespoke widths, depths, and colour options for improved visibility or zoning.
