Product Description
These handrail fittings are used with pultruded FRP profiles. We also supply related FRP products such as pultruded FRP profiles, FRP rebar, pultrusion machines, and pultrusion dies.
FRP (Fiber Reinforced Plastic) and GRP (Glass Reinforced Plastic) handrail fittings are engineered composite components for corrosive and harsh environments. These innovative fittings combine high-strength glass fibers in vinyl ester or polyester resin matrices to create a lightweight, corrosion-resistant alternative to metal systems.
Our comprehensive range includes standard 50mm diameter round fittings and square options (50x50mm, 75x75mm), with various configurations such as 90° elbows, 120° and 135° joints, tees, crosses, and adjustable connectors. Each fitting is manufactured to precise tolerances and includes UV inhibitors, fire retardants, and color-stable pigments for long-term outdoor performance.
These fittings resist corrosion from many chemicals, saltwater, and weathering that can damage metal alternatives. FRP/GRP fittings can offer a long service life with low maintenance requirements in compatible environments.
The non-conductive, non-magnetic properties make these fittings suitable for electrical installations, while their lightweight nature (approximately 75% lighter than steel by weight for equal cross-section) can reduce installation time and transportation costs. Systems can be designed to meet common industrial safety requirements such as OSHA and AS 1657-2013 specifications.

Application Scenarios
Chemical Processing Facilities
Our fittings resist degradation from many acids, bases, and organic solvents. Performance depends on the specific chemical, concentration, temperature, and exposure duration.
Offshore & Marine Environments
Used on oil platforms, coastal walkways, and marina installations. Salt spray performance depends on resin system, fiber architecture, and coating.
Water Treatment Plants
Suitable for clarifier bridges, chemical storage areas, and walkways. Actual maintenance savings depend on operating environment and maintenance practices.
Electrical & High-Risk Areas
Non-conductive properties make these fittings suitable for substations and hazardous areas. Electrical resistance should be verified for the specific application.
Food & Pharmaceutical Processing
The smooth, non-porous surface resists bacterial growth and withstands many cleaning agents. Compatibility should be confirmed for specific sanitizing chemicals.
Product Advantages
Cost Efficiency
- Initial Installation: Modular clamp design can reduce assembly time compared with welded systems
- Maintenance: Low maintenance requirements in compatible environments
- Lifecycle Cost: Total cost of ownership depends on environment, installation, and maintenance practices
Physical Properties
- Strength-to-Weight: High strength-to-weight ratio compared with many metals
- Impact Resistance: Resists typical industrial impacts
- Thermal Insulation: Lower thermal conductivity than aluminum
Safety Benefits
- Electrical Insulation: Non-conductive; suitable for electrical safety applications
- Non-Sparking: Suitable for explosive environments and fuel storage areas where non-sparking materials are required
- Heat Transfer: Lower thermal conductivity can result in lower surface temperatures than metal equivalents in direct sunlight
Frequently Asked Questions
How are the fittings assembled?
The fittings come in two halves that clamp around the tube and are secured with stainless steel fasteners. This modular design allows for quick installation with standard hand tools. No welding, special equipment, or hot work permits are required.
What is the maximum spacing between posts?
For round systems (50mm diameter), the maximum recommended spacing is 1524mm. For square systems, the maximum spacing is 1830mm. These specifications ensure compliance with OSHA and AS 1657-2013 load requirements with a minimum 2:1 safety factor.
Can these fittings be used outdoors permanently?
Yes, our fittings contain UV inhibitors and are suitable for permanent outdoor installation in all climate conditions. UV resistance depends on resin formulation and additives; field performance varies by climate and exposure.
Are custom angles available?
Yes, we offer adjustable fittings that can accommodate angles from 0° to 90°. For special requirements, we can also manufacture custom angle fittings with 2-3 week lead time.
How do these fittings compare to traditional metal systems in lifecycle cost?
Lifecycle cost depends on installation, maintenance, and replacement schedules in the specific environment.
Do you provide design assistance?
Yes, our engineering team offers complimentary design services including 3D modeling, layout optimization, and complete bills of materials. Projects are typically turned around within 5 business days and include detailed installation instructions.
Our fittings connect posts and rails across our full FRP handrail systems range.
