Greenlogy TEC
Pultruded FRP profiles are a new type of composite material made from glass fiber reinforcement, with resin as the binder and glass fiber cloth as the covering reinforcement layer. After thorough impregnation, the material is heated, formed and cured in a metal mold and then pulled by a pulling machine. With good physical properties, it is widely used in high-strength and long-span applications.

Applications:
Greenlogy TEC pultruded FRP profiles are widely used in various applications, combining corrosion resistance, high strength, dimensional stability and light weight, with thermal insulation and non-conductive properties. Durable Greenlogy TEC profiles provide years of low-maintenance service in applications where steel, aluminum or wood components have traditionally been used. Today, these profiles are often used in highly corrosive applications that previously required stainless steel and other costly components.

Applications
Structural Profiles – Curved Flat Bar (Vinylester) is suitable for platforms, walkways, handrails and curved structural supports where corrosion resistance and light weight are required, and is often used together with grating and pultruded profiles. To confirm suitability for your specific service conditions, contact us for detailed specifications and selection advice.
Selection Guidance
When selecting, consider the curve radius, section width and thickness, load-bearing span and installation method together, and ensure compatibility with adjacent components. As multiple specification combinations are involved, contact us for detailed specifications and a quotation, and our technical staff will help confirm a suitable model.
Product Advantages
This profile is pultruded from glass fiber reinforcement and resin, offering light weight, high strength, corrosion resistance, electrical insulation and dimensional stability, making it suitable for high-strength, long-span applications. The vinylester system helps improve resistance to chemical media; actual performance varies with the service environment.
Inquiry
For information on available specification ranges, surface treatment options and delivery arrangements, contact us for detailed specifications and a quotation. Please provide the required section dimensions, curvature requirements and service environment, and we will respond with a corresponding solution.
Service Environment
- Vinylester glass fiber structural profile formulations are suitable for long-term outdoor exposure and resist UV degradation and weathering in industrial and marine atmospheric environments.
- These pultruded profiles can withstand humid, immersed and salt-bearing environments without the corrosion that affects steel, making them suitable for coastal, offshore and chemical plant environments.
- When vinylester resin is selected, they can withstand splashes and vapors of acids, alkalis and solvents; however, direct contact with concentrated or high-temperature chemical fluids should be confirmed against the project's media list.
- Typical installations include walkways, platforms, handrails and cable trays in wastewater treatment, chemical processing and offshore structures, where the profiles remain stable under outdoor temperature fluctuations and condensation.
Custom Cutting
Need panels that fit, or cut to shape? We custom cut FRP grating and profiles to your drawing: panels cut to size or to shape (corner cuts, cutouts), cut edges sealed with resin, and pre-cut and pre-drilled to drawing before shipping. See the custom cutting services.
