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
Solid square rods are suitable for load-bearing, support and connection structures that require strength and durability, such as building frames, bridge ancillary components, platform handrails and industrial equipment supports. Their lightweight, high-strength and corrosion-resistant properties also make them suitable for corrosive environments such as chemical and marine applications. Specific applicable scenarios can be confirmed according to project requirements.
Selection Guide
When selecting, please determine the side length and length of the square rod based on load, span and service environment (corrosion, temperature, etc.), and refer to the dimensions and weights in the table for preliminary matching. If combination with other profiles or secondary processing is required, please specify the connection method and processing requirements. You are welcome to contact us for detailed specifications and selection advice.
Product Advantages
This solid square rod is made of isophthalic resin with fiberglass reinforcement, offering high specific strength, good corrosion resistance and electrical insulation, and is non-magnetic and easy to machine. Compared with traditional metal materials, it is lighter in weight, easier to transport and install, and suitable for applications with high durability requirements.
