Greenlogy TEC
Pultruded FRP profiles are a new type of composite material made with glass fiber reinforcement as the base material and resin as the matrix, with glass fiber cloth as the outer reinforcing layer; after thorough impregnation, they are heated, formed and cured in a metal mold and then pulled and drawn by a pulling machine. They have good physical properties and are widely used in high-strength, long-span applications.

Raw material introduction — resin types
Code | Resin type | Flame retardant performance | Recommended applications |
|---|---|---|---|
VEFR-25 | Vinyl ester type | Oxygen index 28 and above | Harsh corrosive environments such as acids and alkalis |
IFR-25 | Isophthalic type | Oxygen index 28 and above | An economical VEFR-type resin with good, moderate resistance to acids, alkalis and solvents |

Applications:
Greenlogy TEC pultruded FRP structural profiles are widely used in a variety of 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 areas where steel, aluminum or wood components are traditionally selected. Today these profiles are often used in highly corrosive applications that previously required stainless steel and other expensive components.

Application Scenarios
Structural Profiles - Solid Square Rod (Vinylester), with its composite structure of glass fiber reinforcement and resin matrix, is suitable for load-bearing and support applications requiring high strength and larger spans, such as building structures, bridge auxiliary components, industrial platform handrails, and frame connections in corrosive environments. For suitability in specific projects, please contact us to discuss your operating conditions.
Selection Guidance
During selection, you may refer to the cross-sectional dimensions and unit weight of existing specifications (SSR25, SSR32, SSR38, etc.) for preliminary matching based on load requirements, installation space, and corrosion resistance needs. If you have questions about load capacity, span, or connection methods, please contact us for detailed specifications and a quotation, and our technical staff will assist with confirmation.
Product Advantages
This product uses glass fiber cloth as the reinforcement layer; it is impregnated with resin, heat-cured in a metal mold, and pultruded, offering good physical properties and structural stability suitable for high-strength, large-span use. The vinylester material also helps improve corrosion resistance. Please contact us for detailed specifications and a quotation.
Inquiry Guidance
If you wish to purchase Structural Profiles - Solid Square Rod (Vinylester), please provide the required specifications, quantity, and operating environment, and we will propose a suitable solution accordingly. Please contact us for detailed specifications and a quotation, and we will respond to your inquiry as soon as possible.
Operating Environment
- These pultruded solid square rods are designed for structural frames that are both exposed to indoor plant atmospheres and outdoors, and their glass fiber reinforcement and resin matrix resist moisture and weathering, whereas untreated steel would corrode under these conditions.
- Suitable for humid and chemically corrosive environments, such as wastewater treatment, chemical processing, and coastal locations, where composite profiles do not rust and maintain their shape without painting.
- Typical uses include walkway supports, handrail posts, platform frames, and grating clamping components, suitable for indoor and outdoor use and able to withstand temperature fluctuations in normal industrial service.
- For long-term exposure to concentrated acids, strong alkalis, or continuous high temperatures, please inform us of the medium and temperature so that the resin system can be matched to your site conditions before ordering.
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.
