Which grating is right for you?

Answer four questions and we will suggest a starting model, surface and panel size for your environment, use and support span.

This tool gives a recommendation; projects require engineering. We make the final selection together, based on load, span and fixing details.

In what environment will the grating be used?

The environment affects the resin system and the mesh type.

Chemical and treatmentTreatment plants, chemical and petrochemical; contact with acids and alkalis
Marine and salt waterMarinas, ports, shipyards, pools and jetties
Food and hygieneFood and beverage plants, areas that must be kept clean
General industryFactories, energy facilities and substations, cooling towers
Architectural and decorativeFacades, balconies and decorative surfaces

What will the grating carry?

The use determines the load threshold we look for.

Pedestrian walkwayMaintenance walkways, crossings and service areas
Platform, heavy pedestrian loadHeavy foot traffic, work with equipment, crowded platforms
Stair treadsTreads cut from moulded grating, with anti-slip nosing
Over drainage channelsChannel gratings and channel covers
Facade and decorativeCladding and screens that are not walked on

There are people or equipment below the grating; small objects must not fall through.

What is your support span?

The support span is the gap between the two supports (beams or sections) under the grating. The panel bridges this gap unsupported; the larger the span, the lower the load it can carry.

450 mm or lessPlatforms with closely spaced supports, and stair treads. Here 38×38 H38 carries approx. 1,500 kg.
600 mmAt this span 38×38 H38 carries approx. 875 kg.
750–900 mmAt 900 mm 38×38 H38 carries approx. 380 kg.
1000 mm or moreAt 1000 mm 38×38 H38 carries approx. 305 kg; beyond this the value drops quickly.

How slip-resistant does the surface need to be?

The surface does not change the load rating; it changes grip and appearance.

Standard, concaveConcave bar tops; sufficient for most walkways
High, grittedExtra slip resistance for wet, slippery and sloping areas
Smooth, decorativeSanded smooth surface; facade and decorative applications

How is the recommendation calculated?

We use the approximate point load values from our load table. We choose the lightest model that carries at least 300 kg for walkways and stairs, and at least 500 kg for platforms and heavy pedestrian loads.

19×19 mini mesh in food and hygiene areas, or where small objects could fall through to below.
50×50 H50 over drainage channels.
The lightest model with a smooth surface for facade and decorative use.
A gritted, anti-slip nosing on stair treads.

H25, H30, H38 and H50: 38×38 mesh. The 750–900 mm row is calculated with the 900 mm values, the ≥ 1000 mm row with the 1000 mm values.
