Product Overview

Pultruded Fiberglass  Round Tubes are manufactured through a continuous pultrusion process that ensures high fiber content, uniform cross-sections, and consistent quality. Compared to steel, aluminum, or PVC, FRP/GRP round tubes offer excellent resistance to corrosion, impact, and chemicals, making them suitable for demanding environments.

Key Features & Advantages

  • High Strength-to-Weight Ratio – Stronger than steel at a fraction of the weight.

  • Corrosion Resistant – Withstands harsh chemicals, saltwater, and outdoor exposure.

  • Electrical Insulation – Non-conductive material, safe for electrical installations.

  • Dimensional Stability – Maintains shape and performance under temperature changes.

  • Low Maintenance – Reduces long-term costs compared to metal alternatives.
