Mini-mesh FRP grating reduces the open area between bearing bars to create a heel-proof, wheelchair-accessible walking surface that still drains water and resists corrosion. Public pedestrian bridges, pier walkways, and amusement park platforms specify this type for both safety compliance and longevity.

What the Smaller Grid Actually Does
- Heel-proof by design. The 20 mm × 20 mm square opening is small enough that a stiletto heel, a cane tip, or a child's shoe won't punch through. For public infrastructure — pier boardwalks, aquarium viewing platforms, municipal water treatment catwalks — this single detail removes a liability that standard 38 mm grating can't address.
- Drainage without the hazard. Water, rain, and washdown spray still pass straight through. The open area is smaller than standard molded grating, yes, but it's more than enough for surface drainage. What you gain is confidence that dropped keys, phones, and small tools stay on the walking surface instead of disappearing into the sump below.
- Wheelchair and trolley friendly. The flat, fine-grid surface rolls smoothly. Maintenance crews pushing tool carts, visitors in wheelchairs, or families with strollers all cross without bumps or hesitation. Accessibility compliance in public-facing facilities often makes mini-mesh the only grating that passes review.
- Same corrosion backbone. The resin options are identical to standard molded grating — polyester for general outdoor exposure, vinyl ester where chlorine or chemical mist is present. The smaller grid doesn't compromise chemical resistance; it's the same thermosetting resin matrix, just formed around a finer mandrel set.
You'll see this grating underfoot at public aquarium walkways, coastal pier decking, theme park bridge crossings, and water treatment plant catwalks — anywhere the public or unescorted personnel walk over open water or chemical baths. In these settings, the 20 mm grid isn't a preference; it's often written into the safety specification.
Operating Parameters
| Parameter | Typical Range / Value | Notes |
|---|---|---|

| Load rating | Pedestrian live load: 5.0 kN/m² (uniform) | Not rated for forklift or heavy vehicle traffic |
Proven in Field
"The public walkway over our treatment channels used to be steel grating with anti-slip paint — constant repainting, constant complaints about heels getting stuck. We switched to mini-mesh FRP three years ago. No repainting, zero heel incidents, and the visitors' feedback has been entirely positive."
