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
Orthophthalic FRP round tubes are suitable for structural applications requiring strength and corrosion resistance, such as platform handrails, support columns, frame connectors, and various spanning structures. Because they are non-conductive, non-magnetic, and resistant to a range of acid and alkali media, they are also commonly used in humid or corrosive environments such as chemical, water treatment, and marine applications. Contact us to describe your operating conditions, and we can help assess whether they are suitable.
Selection Guide
When selecting, we recommend first confirming the outer diameter and wall thickness (D*T in the table refers to the two parameters of outer diameter x wall thickness), then making a comprehensive assessment based on the actual span, load-bearing method, and installation connection type. Generally, the larger the tube diameter and wall thickness, the higher the section moment of inertia and load-bearing capacity, so a balance must be struck between strength requirements and self-weight and cost. If you provide load conditions and support spacing, contact us for selection advice and detailed specifications.
Product Advantages
This round tube uses fiberglass as reinforcement and resin as the matrix, and is pultruded after impregnation, heating, and curing. It features light weight and high strength, corrosion resistance, electrical insulation and non-magnetic properties, and ease of cutting and drilling. The surface can be treated in different ways to suit outdoor or wear-resistant requirements. Installation generally uses matching connectors, adhesive bonding, or bolts, with relatively low maintenance costs. For specific performance indicators, contact us to request technical data.
Inquiry Guide
If you would like to know the available specifications, colors and surface treatments, packaging methods, and bulk supply arrangements for orthophthalic FRP round tubes, contact us with drawings or operating parameters, and we will provide detailed specifications and a quotation accordingly. You may also tell us the required outer diameter, wall thickness, length, and quantity so that we can respond quickly and assist in confirming shipping and delivery details.
