Beams and channels
Published I-beams extend to about 305 mm depth; channels span compact sections through larger industrial geometries.
F1-STRUX · STANDARD PULTRUDED SHAPES
F1 Composites Pultruded FRP Structural Profiles
F1-STRUX is F1 Composites' published range of standard pultruded fiberglass structural shapes, including I-beams, channels, angles, tubes, flat bars and rods. Buyers can start from a catalog geometry, then confirm the laminate, dimensions, fabrication and documentation for the project.
Reviewed 1 September 2026
Supplier-reported
The range and nominal values are summarized from F1's official catalog and design resources. The quoted laminate, not the shape name alone, controls final properties and suitability.
F1 lists 114 standard profile records. Use them for geometry screening only: the current drawing, section properties, resin grade, tolerance, fabrication and production status must be confirmed in the quotation.
PRODUCT TYPES
What this family covers
Angles and hollow profiles
Equal and unequal angles sit alongside square, rectangular and round hollow sections for framing and support work.
Bars and rods
Flat bars and solid round rods cover secondary members, spacers, supports and application-specific fabrication.
APPLICATION FIT
Where to evaluate it—and where to pause
Typical fit
Industrial platforms, walkway framing, cable support, cooling towers, coastal structures, equipment skids and selected solar or infrastructure assemblies.
Engineering boundary
Do not substitute FRP for steel by outside dimensions alone. Deflection, transverse behavior, local stability, sustained load and connection details can govern.
EVIDENCE BOUNDARIES
What the published evidence does—and does not—support
Representative laminate values
F1's official technical-data page publishes 23 GPa longitudinal tensile modulus, 240 MPa longitudinal tensile and flexural strength, and 30 MPa interlaminar shear for a stated E-glass/isophthalic-polyester laminate.
Standards references
F1 compares the stated laminate with EN 13706 E23 and references ASTM D3917. Confirm the test specimen, method, grade, entity and revision for the offered profile.
