Greenlogy TEC
FRP pultruded profiles are a new type of composite material made with glass fiber as the reinforcement, resin as the binder, and glass fiber cloth as the wrapped reinforcing layer; after being fully impregnated, they are heated, formed and cured in a metal mold and then pulled by a pultrusion machine. They have good physical properties and are widely used in high-strength and long-span applications.

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

Application Scenarios
Thanks to their lightweight, high-strength, corrosion-resistant and insulating properties, FRP I-beams are suitable for corrosive environments such as chemical platforms, offshore facilities, wastewater treatment plants, cooling towers and long-span walkways. Pultruded from glass fiber impregnated with resin, they maintain structural stability under damp, acid/alkali and salt-spray conditions.
Selection Guide
When selecting, please confirm the cross-section dimensions and resin system based on span, load type and support method; isophthalic resin is suitable for medium to high corrosion resistance requirements. For specific specifications and mechanical parameters, please provide your operating conditions and contact us for detailed specifications and selection advice.
Product Advantages
Compared with steel, FRP I-beams are lighter in weight, easier to transport and install, and offer excellent corrosion resistance, electrical insulation and non-magnetic properties. The pultrusion process ensures full fiber impregnation and continuous axial alignment, giving the profiles stable longitudinal strength. For specific performance data, please contact us for detailed technical information.
Inquiry Guide
For specifications, resin systems, custom lengths or bulk purchasing and other commercial terms, please contact us for detailed quotations and technical support. Our engineering team can provide selection assistance based on your project requirements.
Operating Environment
- The I-beams are pultruded with isophthalic unsaturated polyester resin as the matrix and glass fiber as reinforcement, suitable for long-term use in corrosive environments such as damp conditions, acidic/alkaline media and salt spray, and can serve as load-bearing structures in chemical, wastewater treatment, marine engineering and similar applications.
- The profiles resist rusting when used outdoors and are suitable for outdoor platforms, walkways and supports that are exposed to sun and rain over the long term; however, in environments with prolonged strong UV exposure, surface protection measures are recommended.
- The I-beams are lightweight and high-strength, suitable for long-span, high-strength load-bearing conditions; when installed in indoor workshops, underground utility tunnels and other poorly ventilated locations, the applicability of the resin system should still be confirmed according to site conditions.
- For the temperature range, medium concentration and installation load requirements of specific operating environments, please contact us to confirm so that we can recommend suitable specifications and resin types according to your conditions.
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.
