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

Applications:
Greenlogy TEC pultruded FRP structural profiles are used in a wide range 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 performance in areas where steel, aluminum or wood components are traditionally specified. Today these profiles are often used in highly corrosive applications that previously required stainless steel and other costly components.

Application scenarios
FRP angle is commonly used in chemical, wastewater treatment, marine engineering, power and general corrosive environments for platform supports, guardrail frames, cable tray supports and structural reinforcement. Its orthophthalic resin system suits most routine industrial corrosive conditions; for special media such as strong acids, strong alkalis or high temperatures, please contact us with your operating environment so we can recommend a more suitable resin system.
Selection guide
When selecting, first confirm equal or unequal leg, leg width and thickness, then determine the cross-section specification based on span, load direction and connection method; A*B*T1*T2 in the table represent the two leg lengths and their corresponding thicknesses. As FRP is an anisotropic material, we recommend having us verify the load and deflection requirements before finalizing the model; please contact us with your operating parameters for selection advice.
Product advantages
Pultruded FRP angle uses glass fiber as reinforcement and resin as matrix, formed by continuous pultrusion with heat curing. It features light weight and high strength, corrosion resistance, no rusting, non-magnetic and insulating properties, and is easy to cut and drill on site. Compared with traditional steel, it can reduce maintenance and replacement frequency in corrosive environments, making it suitable for applications with both weight and durability requirements.
Inquiry guidance
For specific specifications, dimensional tolerances, surface treatment, packaging and delivery lead times of structural profiles - angle (orthophthalic), please contact us for detailed specifications and quotations. Please also inform us of the required model, quantity, operating environment and delivery destination, and we will provide a targeted solution and commercial terms accordingly.
Operating environment
- This FRP angle uses orthophthalic resin and glass fiber reinforcement, suitable for outdoor and indoor structural frames, especially where conventional steel angle would corrode under humid and atmospheric exposure conditions.
- Typical installation locations include chemical plants, water treatment areas and coastal or humid industrial sites, where the profiles resist splashes, steam and mildly corrosive media without rusting like metal angles.
- The pultruded glass fiber structure keeps the angle stable within the normal service temperature range of industrial buildings and open-air structures, from cold workshops to sun-exposed platforms.
- For continuous immersion, strong solvents or concentrated acid environments, or for load-bearing design, please inform us of your operating conditions so we can confirm the correct resin grade and profile.
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.
