FRP Pultruded Profiles for Industrial Structures
Explore fiberglass square tubes, channels, angles, beams and custom sections for corrosive environments and engineered assemblies. Send a drawing to discuss dimensions, material and fabrication.
Profile shapes
Standard and Custom Pultruded FRP Sections
Choose a section as the starting point. Wall thickness, reinforcement, span and connection details must be confirmed for structural use.
Square & Rectangular Tubes
Profiles for posts, frames, railings and equipment supports, subject to connection and load requirements.
I-Beams & H-Beams
Beam shapes for platforms and framing where span, deflection and connections are engineered for the application.
Angles & C-Channels
Sections for edges, braces, walkways and equipment frames; dimensions and fixings can be reviewed from drawings.
Round Tubes & Rods
Options for rails, handles and specialized components with the required diameter and reinforcement.
Decking Profiles
Interlocking and closed surface concepts for platforms where drainage, traction and supports are specified.
Custom Profiles
Send your drawing to discuss custom section shapes, cut lengths, holes and color options. Feasibility and minimum quantity are confirmed for each specification.
Material selection
Why Choose FRP Structural Profiles?
Pultruded FRP can be useful where corrosion, weight or conductivity affect material selection. Mechanical properties differ by fiber direction, section design and resin.
Corrosion resistance
Select a resin for the chemical medium, concentration and operating temperature.
Light handling weight
Often easier to move and install than comparable metal sections.
Electrical insulation
Discuss tested dielectric requirements for the exact construction.
Custom geometry
Pultrusion supports repeatable profiles and purpose designed sections.
| Factor | FRP profile | Carbon steel | Stainless steel | Aluminum |
|---|---|---|---|---|
| Corrosive exposure | Resin and medium dependent | May require protective coating | Alloy and medium dependent | Alloy and medium dependent |
| Handling weight | Generally lightweight | Comparatively heavy | Comparatively heavy | Lightweight |
| Conductivity | Typically nonconductive* | Conductive | Conductive | Conductive |
| Structural design | Directional properties; deflection often governs | Established isotropic design methods | Established isotropic design methods | Section and alloy dependent |
| Maintenance | Inspect surface and connections | Inspect coating and corrosion | Application dependent | Application dependent |
* Verify electrical properties and applicable approvals for safety critical use. Service life, cost savings and load capacity require project specific calculations and evidence.
Resin selection
Resin Systems and Engineering Data
The exact formulation and test results should be checked against the project specification. Resin families are a starting point for discussion, not a chemical compatibility guarantee.
Orthophthalic polyester
A common starting point for general service where the proposed formulation meets the chemical and temperature requirements.
Isophthalic polyester
An option for selected moisture and chemical exposure conditions. Confirm compatibility for the exact medium and concentration.
Vinyl ester
Consider for more demanding chemical exposure after reviewing the manufacturer's compatibility data and operating temperature.
Fire, smoke and other requirements
Provide the exact test standard, classification, specimen configuration and documentation needed. We will confirm feasible materials and testing before quotation.
Applications
FRP Profiles for Project Assemblies
Combine suitable profiles with gratings or covers where the support layout, joints and loads have been assessed.
Chemical Plant Platforms
Frames, beams and braces can be considered alongside FRP grating for chemically exposed walkways. Define design loads and resin compatibility first.

Technical FAQ
FRP Profile Questions
How are FRP profiles joined on site?
Mechanical fasteners, brackets and engineered bonded joints are possible. Specify joint loads, edge distances, fastener material and environment; verify the connection design before installation.
Can pultruded profiles be used outdoors?
Outdoor performance depends on resin, surface protection, UV exposure and inspection. Request evidence for the actual formulation and expected conditions rather than relying on a universal lifespan claim.
What are the lead time and minimum order quantity?
These depend on the section, tooling, resin, machining and current schedule. Send your size and quantity for a quotation with confirmed timing.
Can FRP beams replace structural steel?
Potentially in an engineered application, but substitution is not one to one. Check strength, stiffness, creep, fire requirements, support layout and connection design using product specific data.
