FRP Pultruded Profiles — Lightweight. Corrosion-Resistant. Long-lasting.
What: Pultruded fiberglass (FRP) structural shapes and rods used across infrastructure, marine, chemical, and civil projects. Why: Superior corrosion resistance, high strength-to-weight ratio, non-conductive properties, and low maintenance — ideal where metal corrodes fast.
FRP Pultruded Profiles — Types Overview
Below is a concise list of common pultruded fiberglass profile types. Each entry links to a deeper product cluster (replace hrefs with your product cluster pages).
FRP Pultruded Round Tube
Hollow circular tubes offering lightweight stiffness and torsional resistance. Common for conduit, shafts, and structural members where a smooth round cross-section is required.FRP Pultruded Rectangular Tube
High moment of inertia in bending for rectangular sections; widely used in railings, frames and platforms where flat faces and easy attachment are needed.FRP Square Tube
Square hollow sections for modular frames, supports and barrier posts — easy to connect with brackets and fasteners for prefabricated assemblies.FRP I Beam
Pultruded I-sections engineered for bending loads with low deflection; excellent for bridge components, decking supports and long-span structures in corrosive environments.FRP U Channel
U channels for mounting, edge protection and as guides in skid rails — combine strength with lightweight handling and corrosion resistance.FRP Angle
Angle sections for frames, bracing and trim — used where cost-effective stiffening with easy bolting is required in corrosive atmospheres.Fiberglass Rebar (GFRP Rebar)
Non-metallic reinforcement for concrete with high tensile strength and superior corrosion resistance, used in coastal, chemical and high-humidity structures.Materials Comparison — FRP Matrix & Reinforcement Options
Quick reference to compare common resin systems and reinforcements for pultruded profiles.
| Material / Property | Typical Properties | Common Applications | Pros | Cons |
|---|---|---|---|---|
| Polyester Resin (Orthophthalic / Isophthalic) | Good general corrosion resistance; economical | General structural profiles, decking, channels | Low cost; good UV variants available | Lower temperature resistance; moderate chemical resistance |
| Vinyl Ester Resin | Improved chemical and fatigue resistance vs. polyester | Chemical tanks, marine components, pultruded beams | Better corrosion resistance and longer service life | Higher cost than polyester |
| Epoxy Resin | Excellent mechanical & thermal properties | High-performance structural parts, aerospace | High strength, excellent adhesion | Costly; more complex processing |
| Reinforcement: E-glass (unidirectional) | High tensile strength along fiber; good stiffness | Beams, rods, rebar, load-bearing profiles | High strength-to-weight; cost-effective | Lower compressive strength vs some specialty fibers |
| Reinforcement: Carbon fiber (hybrid) | Very high stiffness & low CTE | Lightweight high-stiffness pultrusions | Minimal deflection; excellent fatigue performance | Expensive; may be overkill for routine use |
| GFRP Rebar (pultruded) | High tensile, non-corroding | Concrete reinforcement in marine/chemical exposures | No corrosion, electromagnetic neutrality | Different bond behavior to concrete vs steel — design adjustment needed |
Tip: Choose resin first (based on chemical/temperature exposure), then reinforcement architecture for load direction and stiffness requirements.

Selection Guide — Quick Decision Tree
Follow this simplified flow to select the right FRP pultruded profile.
Notes: For structural spans check flexural modulus and section modulus; for concretes use GFRP rebar with correct bond profile (consult our tech team).
Industry Standards & Common HS Codes
- EN 13706 — European standard covering pultruded structural composite profiles, including dimensional tolerances and load-bearing guidance.
- ASTM series — Typical test standards used for pultrusions include ASTM tensile/creep/flexural methods (e.g., ASTM D638 for tensile testing; industry pultrusion practices reference relevant ASTM methods).
- ISO / National Guidelines — ISO and national standards (e.g., ISO guidance for FRP in infrastructure and CSA S806) are commonly used for structural design verification.
Common HS / HTS codes used in trade (examples)
Classification varies by jurisdiction and exact product form. Commonly used headings for pultruded FRP profiles and GFRP rebar include:- 3916.90 / 3921.90 / 3926.90 — Plastic rods, profiles, and other shaped articles are frequent classifications for pultruded profiles in many customs rulings. (Check local tariff notes and provide product technical datasheets to customs broker.)
- GFRP Rebar — Often classified under 3916.90 or similar “plastic rods/profile” headings depending on country practice — always confirm with local customs.

Frequently Asked Questions
Are fiberglass pultruded profiles suitable for outdoor use?
Yes — with UV-stabilized resins and protective coatings, pultruded fiberglass profiles perform well outdoors and resist long-term environmental degradation.
How do I select the right profile for load-bearing applications?
Start with load, span, and deflection limits; check flexural modulus and section modulus; choose resin and reinforcement for exposure; consult our technical team for finite element checks if needed.
Can fiberglass profiles be machined or bolted?
Yes — FRP can be drilled, cut and machined with standard tools (use carbide bits). Use washers and proper torque to avoid local crushing.
What is the typical lead time for custom pultruded profiles?
Lead times depend on tooling needs: stocked profiles ship faster (weeks), custom tooling 4–8+ weeks. Contact sales for exact scheduling.
Are FRP rebars compatible with standard concrete design codes?
GFRP rebars require following FRP-specific design provisions (different bond, modulus, and strength factors). Use applicable codes or seek our engineering support.
