|---|---|
| Mesh size | Mesh opening affects drainage, walking comfort, panel weight and bearing capacity. |
| Resin system | Select resin by chemical, UV, marine or wastewater exposure. |
| Surface | Concave, gritted or covered-top surfaces should match anti-slip and cleaning needs. |
| Panel details | Confirm panel size, cutouts, color, clips, support direction and packing marks. |
Standards reference
FRP Standards and Property References
- FRP grating can be reviewed by thickness, mesh size, resin system, color, surface and project drawings.
- ASTM E84 addresses surface flame spread and smoke development under specified exposure conditions; ASTM D635 addresses burning rate or extent and time of burning of horizontal plastic specimens.
- ASTM D2583 addresses Barcol indentation hardness. A hardness result does not establish a fire classification or grating load capacity.
- For load selection, match the exact product series, clear support span, load case and deflection limit using the FRP grating load and support-span guide. Request the applicable report and match its method, edition and product identity to the purchase requirement.
- Outdoor, wet and pedestrian projects should confirm anti-slip surface, UV exposure, support condition and local access requirements.
- Final specification should follow project drawings, operating environment and buyer approval documents.

FAQ
Molded FRP Grating Buyer Questions
What is molded FRP grating used for?
It is used for wet, chemical, marine and wastewater access areas where corrosion resistance, light weight, drainage and an anti-slip walking surface matter.
What sizes are common?
38 × 38 × 38 mm (thickness × mesh) is a common size for wet access floors. 50 × 50 × 50 mm is a heavier option reviewed by span and load.
Which resin should I choose?
It depends on the real exposure. Send the chemical name, concentration, temperature and contact mode (immersion, splash or washdown). Our screening guide gives candidate resins only; critical service needs supplier data or coupon testing.
How far can molded FRP grating span?
It depends on the product series, thickness, load case and deflection limit. Match your clear span and load with the FRP load and span guide before selecting thickness.
Gritted or concave surface: which one?
A gritted or covered-top surface gives more grip on wet walkways. A concave surface can be enough where cleaning and drainage matter most.
Can molded FRP grating be cut to size?
Yes. Stock panels can be cut to your layout; confirm cutouts, edge condition, clips and support direction before production.
Is FRP grating fire rated?
Fire performance depends on the exact product and test. ASTM E84 covers flame spread and smoke; ASTM D635 covers burning rate. Ask for the report that matches your product and requirement.

FRP chemical-service screening and release
Source: QY-FRP-CRG-01, Rev. 1.0 / 24 Jul 2026. The guide covers early RFQ screening for molded or pultruded grating, treads and structural profiles. On this page it supports selection of the exact molded-grating product; the PDF remains downloadable.
Not a universal chemical-resistance chart: exposure data → resin shortlist → coupon/supplier review → approved service. Unknown chemistry, concentration, temperature, cleaning or load conditions must be escalated. A generic “vinyl ester” label does not make formulations, laminate build, manufacturing process or service limits equivalent.
Open the detailed chemical-service checklist and reference tables
On small screens, swipe wide tables sideways or focus the table and use the left/right arrow keys.
Exposure data required before resin screening
| Input | Required project information | Why it matters |
|---|---|---|
| Chemical identity | Full name, CAS number, mixture/trade name and SDS | Similar names can represent different exposure risks. |
| Concentration | Normal, minimum and maximum concentration | Dilute and concentrated service can behave differently. |
| Temperature | Continuous, normal peak, upset peak and cleaning temperature | Temperature commonly changes the suitability boundary. |
| Contact mode | Immersion, splash, vapor, intermittent washdown or spill only | Continuous wetting is more severe than occasional contact. |
| Duration | Hours per event, cycles per day and design life | Cumulative exposure and cycling influence risk. |
| Mechanical duty | Span, load, impact, abrasion, cut edges and fasteners | Chemical and mechanical degradation can interact. |
| Hygiene/safety | Food contact, potable water, flame/smoke, slip and electrical requirements | May require independent certification or testing. |
Four approval gates
- A — Complete data: identify the exposure, ranges, units and cleaning/upset conditions.
- B — Traceability: identify resin manufacturer, exact family/formulation, batch and laminate construction.
- C — Matching evidence: review evidence for the actual exposure and mechanical duty.
- D — Project release: record accepted service limits and responsible approval.
The following routes are candidates for an evidence request only, not approved resin recommendations or service ratings.
Preliminary shortlist and escalation triggers
| Exposure family | First screening route | Mandatory escalation triggers |
|---|---|---|
| Water, dilute neutral salts, outdoor moisture | General-purpose or corrosion-grade system may be considered. | Elevated temperature, immersion, potable/food contact, freeze-thaw or electrical duty. |
| Dilute acids | Corrosion-grade or vinyl ester candidate; request exact supplier data. | Oxidizing acids, mixed acids, concentration swings or elevated temperature. |
| Alkalis / caustics | Vinyl ester or specialist system candidate. | High concentration, hot cleaning, alternating acid/alkali or stress exposure. |
| Solvents / fuels / oils | Specialist review only; check swelling, softening and fire requirements. | Aromatics, ketones, chlorinated solvents, immersion or temperature cycling. |
| Oxidizers / disinfectants | Exact formulation review plus coupon or supplier confirmation. | Chlorine compounds, peroxide, ozone, high dose, UV and heat together. |
| Unknown mixtures / process liquor | SDS review, process-owner interview and coupon program. | Any missing constituent, proprietary additive or upset chemistry. |
Decision codes — keep the release limitation with the code
| Code | Meaning | Release condition |
|---|---|---|
| P — Provisional | Potential candidate; evidence incomplete | RFQ only; no service claim |
| C — Conditional | Evidence supports stated limits with conditions | Limits printed on approved submittal |
| T — Test required | Coupon or representative laminate test needed | Acceptance criteria agreed before test |
| N — Not recommended | Evidence indicates unacceptable risk | Offer alternative material/system |
| U — Unknown | Insufficient data | Do not quote as technically approved |
Evidence hierarchy and coupon review
- Prefer a test matching the exact product, laminate and exposure.
- Review supplier data for the exact resin and stated limits.
- Use traceable comparable field history with its differences recorded.
- Use public benchmarks only to plan screening or testing, not as proof that QY’s product was tested.
