Greenlogy TEC
FRP pultruded profiles are made with glass fiber as the reinforcement, resin as the binder, and glass fiber cloth as the outer reinforcing layer; after full impregnation, they are heated, formed and cured in a metal die and then pulled by a pulling machine. This new composite material has good physical properties and is widely used in high-strength, long-span applications.

Applications:
Greenlogy TEC pultruded FRP structural profiles are widely used in various applications, combining corrosion resistance, high strength, dimensional stability and light weight, along with thermal insulation and electrical insulation properties. Durable Greenlogy TEC profiles provide years of low-maintenance service in areas where steel, aluminum or wood components are traditionally specified. Today, these profiles are often used in highly corrosive applications that would otherwise require stainless steel and other costly components.

Application Scenarios
Vinyl solid round rods are suitable for load-bearing and insulating components requiring strength, insulation and corrosion resistance, such as chemical platform supports, electrical insulating rods, and marine and wastewater treatment structural parts. They are also commonly used for custom machined parts and sports equipment rods. Contact us to confirm a suitable solution based on your operating conditions.
Selection Guide
When selecting vinyl solid round rods, please confirm the required diameter, length, load-bearing method, operating environment (media, temperature, outdoor exposure) and surface requirements. For insulation or long-term corrosive environments, we recommend providing detailed operating conditions so we can help determine the appropriate resin system and fiber arrangement. Contact us for detailed specifications and selection advice.
Product Advantages
This solid round rod is made of glass fiber reinforcement with a vinyl resin matrix and produced by pultrusion. It features light weight, high strength, insulation, corrosion resistance and weather resistance. It has a smooth surface and can be cut and machined as needed, making it suitable for high-strength, long-span structural requirements. Specific performance varies by specification and process; contact us for the corresponding data.
Inquiry Guidance
For information on the size range, performance parameters, customization possibilities and commercial terms of vinyl solid round rods, please contact us. Provide the required diameter, length, quantity and operating environment, and we will reply as soon as possible. Contact us for detailed specifications and a quotation.
Operating Environment
- Vinyl-type solid round rods are used for indoor and outdoor structural components, including walkways, platforms and support frames, where long-term exposure to weathering and humid environments is expected.
- The vinyl resin matrix and glass fiber reinforcement enable the rods to resist corrosive media commonly found in chemical plants, wastewater treatment and coastal facilities, including splash and vapor exposure.
- These rods are suitable for humid or condensation-prone areas and will not corrode like steel when exposed to water or salt-laden air.
- For high-temperature conditions, chemical compatibility or load requirements beyond the standard range of use, please contact Greenlogy TEC and provide your project conditions so we can confirm suitable specifications.
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.
