Nominal catalog values. This list does not rate load or span: send the clear span, support width, loads and deflection limit with the quotation so the applicable load table can be checked.
After you shortlist a row
1. Load and deflection
Send the clear span, support width, uniform and point loads and the deflection limit. Read how to read a grating load table before comparing offers.
2. Openings and access rules
Check walkway openings, stair and ladder geometry in the ladder, stair and walkway checker, and add stair treads and handrails to the same request.
3. Resin, surface and fixing
Name the chemicals and temperature, the walking surface and the hold-down clips. Full tables are on the molded FRP grating and pultruded FRP grating pages.
Frequently asked questions
What are the standard sizes of FRP grating?
In this catalog, molded FRP grating is listed from 13–65 mm deep in square, mini and large-open meshes, with panels such as 1220 × 3660, 1220 × 2440, 1524 × 4000 and 921 × 3050 mm. Pultruded grating runs from 25–76 mm deep in T-bar, I-bar, high-load and high-open series. General industrial platforms often use 38.1 × 38.1 mm or 40 × 40 mm square mesh; confirm the panel size and cut plan in the quotation.
How much does FRP grating weigh per square meter?
Nominal weights in the published tables are 5.8–52 kg/m² for molded grating and 8.5–73.6 kg/m² for pultruded grating. Enter a floor area in the selector to total the grating weight; clips, cut waste, crating and pallets are extra.
Should I choose molded or pultruded grating?
Molded grating is a two-way mesh panel and is generally more forgiving when a layout needs many irregular cutouts. Pultruded grating carries load in one direction along continuous bearing bars, which suits longer one-way spans and higher stiffness in the span direction. Mark the span direction on the layout when you choose pultruded panels.
Can I select grating by load or span with this tool?
No. The selector compares geometry, open area and weight. Load capacity and deflection depend on the series, clear span, support width, load footprint and deflection limit, so send those with the request and F1 returns the applicable project load table. A load-class label does not replace the table for the selected row.
Is open area the same as the clear opening?
No. Open area is the share of the panel surface that is open. A mesh designation or bearing-bar spacing is a center distance, not a clear opening. For single square molded meshes the selector estimates the top opening as mesh pitch minus top bar width; check mini meshes, pultruded rows and any accessibility or heel-gap rule on the order drawing.
