Micro & Mini Mesh GRP Grating Panels

Tighter-opening molded GRP panels — heel-friendly, ADA toe-passing, small-part-retentive.

Product Overview

Micro & Mini Mesh GRP Grating Panels

Standard molded GRP grating uses 38 x 38 mm openings. Micro mesh (mini mesh) GRP grating shrinks the opening to 12, 15 or 20 mm while keeping the corrosion-proof, anti-slip properties of molded GRP — so high heels, wheelchair casters and small tools no longer drop through. On the standard 1220 x 3660 mm panel, micro mesh is offered alongside the Mini-Mesh 19.05 mm top over a 38.1 mm base.

Openings 12 / 15 / 20 mm square, plus Mini-Mesh 19.05 mm top over 38.1 mm bottom
ADA toe-passing: openings at or below about 13 mm keep heels and casters from dropping through
Blocks small tools, screws and parts falling through to equipment below
Grit-top option: coefficient of friction 0.6-0.8 dry, 0.5-0.7 wet
GRP panels up to 1220 x 3660 mm; thickness 25 / 30 / 38 / 40 / 50 mm
Flexural strength about 110 MPa (ASTM D790); Barcol hardness 40-50 (ASTM D2583)

Configurations

GRP Grating Configuration Options

Opening	Best For	Key Benefit
12 mm	Fine particle control, heel pins, small foot traffic	Stops the smallest tools and parts
15 mm	Pedestrian decks, rooftop walkways, ADA routes	Balances toe-passing safety with open area
20 mm	General anti-slip pedestrian and light service	More drainage than 12/15 mm, still heel-friendly
19.05 mm Mini-Mesh	Public access, ADA-compliant small openings	Mini-Mesh top over 38.1 mm base (about 44% open)

Reserve micro mesh for the walking and working zones, and use standard 38 mm mesh on purely drainage or equipment decks where no one walks regularly — that puts the heel-friendly, part-retentive surface exactly where it is needed. Panels are fixed with SS304/SS316 clips, a 3-5 mm expansion gap and a minimum 40 mm bearing on supports.

FAQ

Frequently Asked Questions

What micro mesh opening should I use for an ADA-accessible walkway?

Choose a 12 mm or 15 mm opening. Openings at or below roughly 13 mm prevent thin high heels and small wheelchair casters from dropping through, which is the core concern for accessible routes. Add a grit-top surface for wet-weather slip resistance.

Is micro mesh stronger than 38 mm standard grating?

Panel span rating depends mainly on thickness and glass content, not opening size. A micro mesh panel feels stiffer under foot because it distributes a point load over more bars, but for long spans or heavy loads select the correct thickness or pair it with pultruded supports.

Does the smaller opening reduce drainage too much?

Yes, open area is lower than 38 mm mesh. For walkways and equipment decks that is rarely a problem; for high-flow trench covers use standard mesh, or use micro mesh only on the pedestrian strip.

What thickness micro mesh panel do I need?

Thickness follows the support span and load across the molded range of 25, 30, 38, 40 and 50 mm on the 1220 x 3660 mm panel; 38 mm is the workhorse for mixed pedestrian and light equipment traffic.
