Application:
Genius© pultruded fiberglass structural shapes from Genius Composite Inc. are used in a wide range of applications and provide a unique combination of corrosion resistance, high strength, dimensional stability and light weight, along with thermal and electric non-conductivity. Durable Genius shapes provide years of low maintenance service in areas where steel, aluminum or wood components are traditionally specified. Today ,these shapes are often used in highly corrosive applications where stainless steel and other expensive components were once required.

Application Scenarios
This U-channel square tube handrail profile is suitable for building railings, bridge pedestrian handrails, platform and walkway edge protection, and other applications requiring strength and corrosion resistance. Its fiberglass-reinforced structure is suitable for long-span, high-strength installation environments, and can also be used in chemical, coastal, and other projects susceptible to moisture and chemical media. Please contact us to confirm a suitable solution based on your project conditions.
Selection Guide
During selection, you can start with cross-sectional dimensions, wall thickness, and unit weight, and match them with handrail span, installation method, and load-bearing requirements. The table provides various A*B*T specifications and their corresponding weights, making it easy to do an initial screening according to structural design requirements. If you need recommendations for specific spans and loads, please contact us for detailed specifications and selection advice.
Product Advantages
This profile uses fiberglass as reinforcement and resin as binder, and is formed through impregnation, heated compression molding and curing, and pultrusion. It offers good physical properties and corrosion resistance. Compared with traditional metal profiles, it is lighter in weight, making transportation and on-site installation easier, while also being suitable for high-strength and long-span applications. Specific performance must be evaluated based on actual service conditions. Please contact us for further information.
