FRP Rectangular Tubes

Product Overview

FRP Rectangular Tubes are manufactured using the pultrusion process, combining fiberglass reinforcements with high-quality resins. This results in strong, non-conductive, and corrosion-resistant structural profiles suitable for indoor and outdoor environments.

Key features include:

• Superior strength-to-weight ratio

• Resistance to chemicals, moisture, and UV rays

• Non-magnetic and electrically non-conductive

• Easy fabrication and installation
