FRP (Fiber Reinforced Plastic) structural profiles — including channels, angles, and tubes — are lightweight, corrosion-resistant alternatives to steel and aluminum in modern construction.
Made through pultrusion technology, these components offer high strength-to-weight ratios and excellent resistance to chemicals and moisture, making them ideal for industrial, marine, and civil engineering use.

FRP channels are commonly used for framing, supports, and walkway systems.
They come in standard dimensions such as C100×50×6 mm and C150×75×8 mm, with tensile strengths around 240–300 MPa.
Compared to steel, they are 75% lighter and easier to install without welding.
Typical applications:
Cable trays and supports
Structural framing
Roof and wall systems
FRP angles are primarily used in reinforcing corners, brackets, and joint structures.
Standard sections range from 25×25×3 mm up to 100×100×10 mm.
They provide exceptional dimensional stability and resist deformation under load.
Applications include:
Handrail frames
Cooling tower reinforcements
Bridge guardrails
FRP tubes — both square and circular — serve as columns, conduits, and supports in load-bearing systems.
The pultruded surface ensures uniform fiber distribution, allowing them to handle axial and torsional stresses effectively.
Typical strength: Flexural strength up to 400 MPa, Elastic modulus 25 GPa.
Applications:
Structural posts
Electrical conduits
Equipment supports
| Property | Typical Value | Comparison to Steel |
|---|---|---|
| Tensile Strength | 240–350 MPa | ~60% of steel |
| Flexural Strength | 400 MPa | ~70% of steel |
| Density | 1.8–2.0 g/cm³ | 25% of steel |
| Corrosion Resistance | Excellent | High |
| UV Resistance | Good with coating | Moderate |
These profiles are electrically non-conductive, non-magnetic, and maintenance-free, reducing lifecycle costs by up to 40% compared to galvanized steel structures.
The price of FRP channels, angles, and tubes depends on multiple variables:
Raw materials: Glass fiber type and resin (polyester, vinyl ester, epoxy)
Cross-section size and thickness
Surface treatment (painted, coated, or UV-protected)
Order volume and customization
Typical pricing (2025 average):
FRP Channel: USD $8–$12 per kg
FRP Angle: USD $7–$10 per kg
FRP Tube: USD $9–$13 per kg
Although the unit cost may exceed that of mild steel, the installation speed, corrosion resistance, and reduced maintenance make FRP the lower-cost option long-term.
FRP profiles are widely used in:
Bridges & Infrastructure: structural reinforcement, cable support
Chemical Plants: corrosion-resistant frameworks
Cooling Towers: lightweight, moisture-proof structures
Marine & Offshore: saltwater-resistant components
Architectural Projects: decorative frames and lightweight panels
They are also compatible with bolted, riveted, or adhesive joints, providing flexibility for prefabricated modular construction.
When sourcing FRP structural profiles, engineers should verify:
ASTM D638 / D790 (mechanical properties)
ISO 527 (tensile testing)
BS EN 13706 (pultruded profiles classification)
Many manufacturers, such as GTOFRP, provide custom dimensions, engineering drawings, and cut-to-length supply for international projects.

FRP channels, angles, and tubes are transforming how industrial and civil structures are designed.
By offering high strength, low weight, and excellent durability, they outperform traditional steel in environments where corrosion, weight limits, or conductivity matter.
For long-term infrastructure projects, fiberglass profiles deliver both performance and value.
