Panel Count Calculator
FRP Grating Panel Count Calculator
Estimate how many standard panels cover a rectangular area. Standard molded and pultruded panels are 1.22 × 3.66 m (4 × 12 ft). Enter the area dimensions and a waste allowance; the tool proposes an orthogonal layout and reports the panel count, covered area and layout waste.
1 · Inputs
The tool lays panels with the panel length along the area length. Pultruded bearing bars must run across the support span — confirm orientation with engineering before ordering.
Run the calculation to see the panel count.
Enter your area and press Calculate Panels — panel count, layout, covered area, waste and an order suggestion.

Design basis: ZeAllgrate (Fiberglass Grating Manufacturers Council / ACMA) design guidelines; ASTM D790 (flexural properties), ASTM D638 (tensile), ASTM D648 (heat deflection) and ASTM E84 (surface burning). Resin property data based on Ashland / Reichhold technical datasheets. All outputs are INDICATIVE estimates for specification guidance only — they are NOT a substitute for certified load/span charts, approved resin datasheets or professional engineering judgment. Final design must be verified by ZeAllgrate engineering.
