Interactive FRP Design Tools
Run a quick indicative estimate in your browser, then hand the numbers to our engineers for a certified, project-grade specification. These tools are deliberately simple — they model a grating panel as a simply-supported beam on representative material properties, not as a finite-element model.
Load & Span Calculator
Model a molded or pultruded panel as a simply-supported beam. Enter panel type, thickness, clear span, load type and your deflection limit — the tool returns computed deflection, allowed deflection and a PASS / FAIL verdict with a recommended next thickness.
Open Calculator →Resin Selection Wizard
Answer five questions — chemical environment, peak temperature, UV exposure, fire/smoke requirement and food contact — and the wizard scores five resin systems (orthophthalic, isophthalic, vinyl ester, FR vinyl ester, phenolic) and ranks the best fit with pros, cons and a cost index.
Open Wizard →Panel Count Calculator
Estimate how many standard 1.22 × 3.66 m (4 × 12 ft) panels cover a rectangular area. Enter the area length, width and a waste allowance — the tool proposes an orthogonal layout and returns the panel count, covered area and waste percentage.
Open Calculator →How to Use These Tools
Indicative, not certified
Outputs are first-pass estimates on representative E-values and idealised section properties. Use them to compare options and size a project concept, not to issue a final fabrication drawing.
Engineering sign-off
Every purchase should be closed out against ZeAllgrate certified load/span charts and approved resin datasheets, which already carry the ZeAllgrate working-load safety factor (~4:1–5:1).
Send us the input
Paste your span, load, chemistry and code requirement into the contact form — engineers return a written recommendation and certified data within one business day.

Want a Certified Specification, Not an Estimate?
Send clear span, UDL, any point load, your deflection limit and the chemicals involved — ZeAllgrate engineers return the exact panel, resin and load chart.
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.
