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
Vinylester square tubes are suitable for platforms, handrails and support structures in chemical, papermaking, electroplating and other environments with acid and alkali corrosion, and are also commonly used where electromagnetic insulation and lightweight high strength are required. For corrosion resistance performance under specific environments, please contact us to confirm based on the medium and working conditions.
Selection Guide
During selection, the side length and wall thickness of the square tube can be determined according to load, span and connection method, and general-purpose and vinylester types can be distinguished to meet different corrosion resistance requirements. If you provide the working conditions and load conditions, we can assist in recommending suitable specifications. Welcome to contact us for detailed specifications and quotations.
Product Advantages
This square tube uses glass fiber as reinforcement and resin as binder, and is formed by pultrusion. It features lightweight high strength, corrosion resistance and insulation, making it suitable for replacing some metal profiles. The surface can be treated in different ways as needed; please communicate with us for specific available options.
Inquiry Guide
If you need information such as the size range, weight, color and packaging of the square tube, welcome to contact us for detailed specifications and quotations. Please provide the required specifications, quantity and usage environment, and we will reply as soon as possible.
