Slips and falls are among the most common industrial injuries, which is why anti-slip FRP grating is specified across walkways, platforms, stair treads and trench covers. This guide explains how anti-slip fiberglass grating surfaces work, which standard to apply, and how to choose the right surface profile for your application.

What makes FRP grating anti-slip?

Anti-slip FRP grating embeds grit or forms a mechanical profile on the walking surface to increase the coefficient of friction (COF). ZeAllgrate offers three proven surface systems: a fused grit-top surface that bonds angular silica to the panel, a concave surface with a chamfered, self-draining profile, and a sand-embedded surface for wet and oily environments. Each is factory-applied during molding, so the slip resistance is part of the panel, not a coating that wears off.

Grit-top vs concave vs silica-embedded

Grit-top panels are the most widely specified: angular quartz grit is embedded into the top of the panel to bite footwear and reduce slip, ideal for general walkways and platforms. Concave surfaces are chamfered so water, oil and debris drain off the walking line, keeping the surface drier and safer outdoors. Silica-embedded surfaces maximise grip in wet, greasy or food-processing environments where standing moisture is common. For most industrial work, a grit-top surface gives the best balance of grip and cleanability.

Slip-resistance standards and COF

The most relevant references for anti-slip FRP grating are the Americans with Disabilities Act (ADA) coefficient-of-friction guidance, ASTM F1637 for walking surfaces, and DIN 51130 for ramp and stair slip testing in Europe. A COF of 0.5 or higher is generally considered slip-resistant for dry walking surfaces. When you specify anti-slip grating, confirm the target COF and the applicable standard for your country and application — ZeAllgrate can supply test data for the surface you choose.

Where anti-slip FRP grating is required

Use anti-slip FRP grating anywhere people walk on composite flooring: industrial plant platforms, offshore decks and marine environments, wastewater treatment walkways, chemical plant platforms, solar rooftop walkways, trench covers and stair treads. The corrosion resistance and light weight of FRP grating combine with the anti-slip surface to deliver safe, long-life access in aggressive environments where steel rusts.

Choosing the right anti-slip surface

Match the surface to the exposure: general dry walkways → grit-top; outdoor or wet areas → concave; heavy oil, grease or food processing → silica-embedded. If your walkway sees frequent chemical washdown, confirm the resin system (polyester, isophthalic or vinyl ester) matches the chemicals. ZeAllgrate manufactures both molded and pultruded anti-slip panels and can quote cut-to-size sections for your project.
