FRP I beams — also known as fiberglass H beams or pultruded FRP I beams — are widely used in industrial structures, platforms, walkways, and infrastructure projects. Picking the right size and configuration matters for both structural safety and cost efficiency.
As a professional FRP I beam manufacturer and equipment supplier, we offer both standard and fully customized FRP I beam solutions for customers worldwide.
Standard FRP I Beam Sizes
FRP I beams are made via the pultrusion process, giving consistent cross-sections and stable mechanical properties. Typical standard sizes include:
| Beam Depth (mm) | Flange Width (mm) | Web Thickness (mm) | Typical Applications |
|---|---|---|---|
| 100 – 152 | 100 – 152 | 6 – 10 | Platforms, walkways |
| 200 – 254 | 150 – 200 | 8 – 12 | Industrial flooring |
| 300+ | 200+ | 10 – 15 | Heavy-duty structures |
Standard sizes suit most applications, but many projects need something more specific.
Custom FRP I Beam Options
We offer fully customized FRP I beams based on project requirements, including:
- Custom beam depth, flange width, and wall thickness
- Fiber volume ratio optimization for strength or stiffness
- Different resin systems: polyester, vinyl ester, epoxy
- UV resistance, fire retardant, and anti-slip surface options
- Color customization for safety or branding
Custom FRP I beams are commonly used in chemical plants, marine environments, wastewater treatment facilities, and offshore platforms.
Manufacturing Process
FRP I beams are produced via pultrusion, which ensures consistent quality and high fiber alignment along the load direction.
| Manufacturing Step | Description |
|---|---|
| Fiber Reinforcement | Continuous glass fibers provide longitudinal strength |
| Resin Impregnation | Fibers are impregnated with selected resin system |
| Heated Pultrusion Mold | Beam shape is formed and cured under controlled temperature |
| Cutting & Finishing | Profiles are cut to length and surface finished |
The result: stable mechanical performance and excellent dimensional accuracy.
Quality Control and Testing
FRP I beams can be supplied with third-party test reports, including:
- Tensile testing (ASTM D638)
- Compression testing (ASTM D695)
- Flexural testing (ASTM D790)
Verified mechanical data helps engineers and project owners confidently replace steel beams with FRP.
