Greenlogy TEC
FRP pultruded profiles are a new type of composite material that uses glass fiber reinforcement as the base material, resin as the binder, and glass fiber cloth as an outer reinforcing layer. After thorough impregnation, the material is heated, formed and cured in a metal mold and then pulled by a haul-off machine in a pultrusion process. With good physical properties, these profiles are widely used in high-strength and 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 deliver years of low-maintenance service in areas where steel, aluminum or wood components have traditionally been specified. Today, these profiles are commonly used in highly corrosive applications that previously required stainless steel and other costly components.

Application Scenarios
Y-shaped FRP profiles (vinyl ester) are suitable for supporting and connecting parts that require strength, corrosion resistance and electrical insulation, such as platform edge beams, walkway handrail frames, cable tray supports and structural components in chemical environments. Specific installation locations and accessories can be confirmed against your project drawings; contact us for application advice.
Selection Guide
When selecting, first confirm the cross-section dimensions (A×B×T), single-piece length, load-bearing direction and operating environment (corrosive media, temperature, UV exposure, etc.), then determine the model against the specifications in the table above. If you provide the load conditions and installation method, we can help recommend a suitable cross-section and wall thickness.
Product Advantages
This profile uses glass fiber reinforcement and a resin matrix, formed by the pultrusion process. It offers light weight and high strength, corrosion resistance, no rusting, insulation and non-magnetic properties, and is easy to drill and cut for installation. Vinyl ester resin systems are typically used in applications with higher chemical resistance requirements; specific performance should be assessed according to operating conditions.
Inquiry Guidance
For detailed datasheets, custom lengths, surface treatment or bulk supply solutions, contact us for detailed specifications and quotations. Please provide the required cross-section, quantity, length and operating environment, and we will reply as soon as possible.
Operating Environment
- Y-shaped FRP structural profiles are suitable for indoor and outdoor installation in industrial and civil buildings, including high-strength and long-span applications.
- The glass fiber reinforced resin matrix resists moisture and atmospheric attack, so with correct selection the profiles are suitable for humid or coastal environments.
- They are suitable for environments with chemical vapors, weak acids or alkalis, because the composite structure and resin binder are corrosion resistant.
- Typical uses include structural frames, supports and profiles in factories, walkways and platforms where weather resistance and chemical resistance are required.
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.
