Manufacturing Process: Visual Flow Diagram of FRP Grating Factory
- Material Preparation： Glass fiber strands, resin, and additives mixed and prepared.
- Molding/Assembly: Raw mix is poured into standardized steel molds or hand-laid to precise grp grating sizes (e.g. 38x38mm, 50x50mm mesh).
- Heat Curing & Hardening: Automated curing (at 120–200℃) cross-links polymers for glass-like strength.
- Demolding & Surface Finishing: Grating is removed, edges trimmed, surface grit applied for slip resistance.
- Quality Inspection: Rigorous load, fire, and chemical resistance testing as per ISO/ANSI standards.
- Packing & Warehousing: Final product packaged for worldwide shipment.
The entire process is strictly monitored under ISO9001 and ANSI/ACMA guidelines, ensuring material reliability and consistent fibreglass reinforced plastic grating quality.
Key Materials Explained:
- Resin Type: Ortho/Isophthalic, Vinyl Ester (for high chemical/corrosion resistance)
- Glass Fiber Content: ≥30% by weight, ensuring structural robustness
- Additives: Anti-UV, Fire Retardant, Anti-slip quartz

Why Choose a frp grating factory? Core Advantages
- Exceptional Corrosion Resistance – Unmatched suitability for chemical labs, oil refineries, wastewater plants (outperforming steel in acidic/alkaline and marine atmospheres).
- Lightweight & High Strength – 1/4 the weight of steel but extremely robust; simplifies on-site installation, reduces support structure cost.
- Electrical & Thermal Insulation – Ensures operational safety in high-voltage or corrosive settings.
- Customizable Design – Mesh size, color, resin type, panel dimension tailored to unique project layouts.
- Long Service Life & Low Maintenance – Typical service: 25 years+, requiring minimal upkeep compared to traditional gratings.
- Fire Retardancy & Anti-Slip – Optional surface grit, meets UL94/V-0 and ASTM E84 flame requirements.
Comparison: FRP Grating vs Steel Grating
| Feature | FRP Grating | Steel Grating |
|---|---|---|
| Weight (kg/m2) | ~12 | ~35 |
| Corrosion Resistance | Excellent | Poor/Needs Coating |
| Electrical Safety | Insulating | Conductive |

FAQ: Professional Questions & Answers for FRP Grating Solutions
- 1. What is the main difference between molded and pultruded frp grating?
-
Molded grating: Made by setting materials in interconnected mesh molds, offering superior bi-directional load transfer; used in complex layouts.
Pultruded grating: Produced by pulling continuous glass fibers through a resin bath and heated die; excels in longer spans, higher unidirectional strength. - 2. How is the fire resistance of FRP grating ensured?
- FRP gratings can be produced with halogen-free resins and fire retardant additives, achieving UL94 V-0 and ASTM E84 Class 1 standards.
- 3. Which certifications are crucial when evaluating a frp grating factory?
- Essential certificates include ISO9001 (quality), SGS/CE (international compliance), EN13706 (Europe), and custom industry-specific accreditations like FDA (for food sector).
- 4. What installation standards and guidelines must be followed?
- Reference ANSI/ACMA FRP-1 and EN ISO 14122-2 for grating platform installation; proper clip spacing, load direction, and edge banding are mandatory for safety.
- 5. How do grp grating sizes affect load capacity?
- Larger mesh (e.g. 50x50mm) reduces weight but provides lower load rating per area. Consult factory load tables for precise deflection and span data.
- 6. Can FRP grating resist UV exposure and outdoor aging?
- Yes. Fibreglass reinforced plastic grating with UV inhibitors and anti-aging coatings maintain color/strength for 10+ years outdoors (tested per ASTM G154).
- 7. What's the typical delivery cycle & warranty?
- Standard lead time: 7–15 business days. Warranty: 12–36 months against delamination, corrosion, critical failure depending on application.
