When specifying translucent roofing panels for industrial or agricultural buildings, the choice between FRP (Fiberglass Reinforced Plastic) and polycarbonate is one of the most common decisions engineers and contractors face. This comparison covers the key differences to help you make the right choice.

Material Composition

FRP panels are made from glass fiber reinforcement embedded in a polyester or vinyl ester resin matrix. The result is a composite material with excellent corrosion resistance and good structural properties.

Polycarbonate sheets are thermoplastic panels made from polycarbonate resin, offering exceptional impact resistance and optical clarity.

Performance Comparison

Property FRP Panel Polycarbonate
Impact Resistance Good Excellent (200× glass)
Light Transmission 70–90% 82–88%
Corrosion Resistance Excellent Good
UV Resistance Good (with gel coat) Excellent (co-extruded)
Service Life 20+ years 10–15 years
Cost Lower Higher
Weight Similar Similar

When to Choose FRP

  • Chemical plants or agricultural facilities with corrosive environments
  • Large industrial roofing projects where cost is the primary factor
  • Applications requiring 20+ year service life with minimal maintenance
  • Poultry farms, pig farms, or aquaculture facilities

When to Choose Polycarbonate

  • Applications requiring maximum impact resistance (hail-prone regions)
  • Greenhouses where precise light transmission control is important
  • Architectural applications where optical clarity is required
  • Carports, bus shelters, and public infrastructure

Conclusion

Both FRP and polycarbonate have their place in modern construction. For most industrial roofing applications, FRP offers better value. For impact-critical or architectural applications, polycarbonate is the preferred choice. Contact Bonai for a project-specific recommendation.
