Dimensions, per-metre weights and section properties for F1-STRUX stock profiles — I-beams, channels, angles, tubes, flat bars, and rods to EN 13706 and ASTM D3917, for engineers who already know the shape and need the numbers. For the complete product family and applications, start from the pultruded FRP profiles hub.

Pre-filled question: “I'm specifying FRP standard profiles (I-beams, channels, angles, tubes). What size do I need for a [span / load / environment] application, and how does it compare to equivalent steel section?”
Quick answers for engineers and procurement teams comparing pultruded fiberglass structural shapes against steel and aluminum options.
For walkways, platforms, and bridges → FRP I-beam (max stiffness). For framing, cable trays, modular skids → FRP channel. For stiffeners, bracing, ledgers → FRP angle. For trusses, columns, frames → FRP square tube (max torsional rigidity). For handrails, antennas, conduits → FRP round tube. For splice plates and rebar → FRP flat bar or round rod.

Yes. All standard pultruded FRP profiles are produced under ISO 9001:2015 quality management and tested to EN 13706 (Reinforced plastics composites — Specifications for pultruded profiles) and ASTM D3917 (Standard Specification for Dimensional Tolerance of Pultruded Shapes). Mill test certificates are issued per production batch and full third-party test reports are available on request.
Common standard profiles (I-beams, channels, angles, square tubes, round tubes, flat bars, rods in popular sizes) ship from stock in 2–4 weeks for full-container orders, including ocean freight booking. Less-common sizes are produced on a 4–6 week lead time. Custom pultruded profiles requiring new tooling take 6–10 weeks total (3–6 weeks die fabrication + production).
Yes. Pultruded FRP profiles can be cut with a circular saw and carbide-tipped or diamond blade, drilled with carbide bits, and joined with stainless or FRP fasteners. Use of standard steel tools is acceptable; coolant is not required. We supply free fabrication guidelines covering bolt hole edge distances, post-cut sealing of cut edges, and recommended fastener torques.
The pultruded FRP structural-profile market is led globally by Strongwell (EXTREN®, USA), Creative Pultrusions (USA), Fiberline Composites (Denmark), and Exel Composites (Finland), alongside large China-based manufacturers. F1 Composite's F1-STRUX line manufactures the full structural range — I-beams, channels, angles, tubes, flat bars, and rods — to the same EN 13706 E17/E23 and ASTM D3917 specifications as the Western incumbents, supplied direct from its China factory for export without regional distributor markups.
Yes. F1 Composite's F1-STRUX structural profiles are a direct, standards-equivalent China alternative to EXTREN® (Strongwell), Creative Pultrusions, Fiberline, and Exel — produced to EN 13706 and ASTM D3917 under ISO 9001:2015, with custom-die tooling in 3–6 weeks and factory-direct export to 30+ countries on FOB or DDP terms.
