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
Structural Profiles - Flat Tube (Isophthalic) is commonly used for load-bearing and support structures requiring strength and corrosion resistance, such as platform frames, guardrail posts, walkway supports and equipment frames. The isophthalic resin system is suitable for humid, acid/alkali or outdoor exposure environments, and can replace some metal profiles in various working conditions. For specific applications and installation methods, please contact us.
Selection Guide
When selecting, consider the load direction, span, connection method and environmental medium, and weigh the cross-sectional dimensions, wall thickness and resin system of the flat tube. The dimension table on this page lists the cross-section and unit weight of each specification for preliminary comparison, but actual load-bearing and deflection must be confirmed by engineering design. For selection advice for specific projects, please contact us for detailed specifications and quotations.
Product Advantages
The pultrusion process arranges glass fibers continuously along the axial direction, giving the flat tube high axial strength and stiffness, while also possessing the characteristics of FRP materials such as light weight, corrosion resistance, non-magnetic, insulation and easy processing. The isophthalic resin system further improves resistance to humid and chemical environments, facilitating on-site cutting, drilling and bolted connections. For specific performance, please inquire.
