FRP Square & Rectangular Tubes
Pultruded FRP SHS and RHS profiles from 25×25 mm to 240×240 mm.
Closed-section structural tubes
FRP square and rectangular tubes deliver superior torsional rigidity for columns, trusses, and frame structures. Multi-axial reinforcement provides structural integrity in both directions. The smooth interior bore allows dual use as conduits or cable enclosures with inherent dielectric properties.

Frequently Asked Questions
What is the advantage of FRP square tubes over open profiles?
Closed-section square tubes deliver superior torsional rigidity compared to I-beams or channels, making them ideal for columns, trusses, and structures that resist combined bending and torsion. The smooth interior bore also allows use as conduits or cable enclosures.
Are rectangular hollow sections (RHS) available?
Yes. In addition to square sections (SHS), we stock rectangular hollow sections including 80×60, 100×60, and 120×60 mm. Custom rectangular sizes are available via our custom pultrusion service.
