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
Quatrefoil tube (vinyl ester) is commonly used for structural supports, handrails, platform frames, and in chemical, marine, and other environments requiring corrosion resistance and strength. Its multi-lobed shape facilitates combination with other profiles, making it suitable for space-restricted or lightweight applications. For specific applications, please consult our technical team for selection based on your operating conditions.
Selection Guidance
When selecting, the cross-sectional dimensions and wall thickness of the tube should be determined based on load, span, corrosive environment, and installation method. Quatrefoil tube provides multi-directional load-bearing characteristics, making it suitable for combined stresses. Please contact us with your detailed operating conditions, and we will assist you in choosing the appropriate specifications.
Product Advantages
Fiberglass reinforced composite (FRP) quatrefoil tube is lightweight, high-strength, corrosion-resistant, insulating, and non-magnetic, and easy to process and install. The vinyl ester resin matrix further enhances chemical corrosion resistance, making it suitable for harsh environments. Compared with metal, it offers long service life and low maintenance cost.
