Greenlogy TEC
FRP pultruded profiles are a new type of composite material made from glass fiber reinforcement, with resin as the binder and glass fiber cloth as the wrapping reinforcing layer. After thorough impregnation, they are heated, formed, and cured in a metal mold and pultruded under the haul-off traction of the pultrusion machine. They have good physical properties and are widely used in high-strength, large-span applications.

Applications:
Greenlogy TEC pultruded FRP profiles are widely used in various applications, combining corrosion resistance, high strength, dimensional stability and light weight 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 used. Today, these profiles are often used in highly corrosive applications that previously required stainless steel and other costly components.

Application scenarios
Structural profile flat bar is suitable for load-bearing and connection locations with requirements on strength and span, such as platform supports, handrails and railings, walkway grating frames, equipment supports, and structural members in corrosive environments such as chemical and marine applications. Its glass fiber reinforced resin system has practical application value in situations requiring insulation, light weight, and corrosion resistance. For specific working conditions, selection should be confirmed with us based on load and media conditions.
Selection guide
Selection mainly considers width, thickness, required load-bearing capacity, support span, and service environment. Different specifications in the table correspond to different moments of inertia and weights, and can be matched according to installation space and force conditions. If splicing, openings, or combination with other FRP components are involved, we recommend providing drawings or service conditions. You are welcome to contact us for detailed specifications and selection advice.
Product advantages
This flat bar is formed by the pultrusion process, with continuous fiber distribution, providing relatively high longitudinal strength and stiffness, while also possessing the light weight, corrosion resistance, electrical insulation, and maintenance-free characteristics common to FRP materials, and is easy to cut and install on site. Compared with traditional metal profiles, it can reduce corrosion and maintenance costs in corrosive or electromagnetically sensitive environments, and the surface can be provided with different treatments as required.
Inquiry guidance
To confirm specific specifications, length, surface treatment, and packaging method, please provide the application scenario and quantity requirements. We can recommend suitable models according to your project conditions. You are welcome to contact us for detailed specifications and quotations; we will arrange a dedicated contact and provide technical support.
Service environment
- This pultruded FRP flat bar is suitable for indoor and outdoor use, where the glass fiber reinforcement and resin matrix resist moisture and humidity without swelling or rusting.
- In industrial plants and chemical processing areas, the flat bar resists attack by corrosive media such as acids, alkalis, and salts, and is suitable for environments where steel would degrade.
- As a structural profile for high-strength, long-span situations, it maintains dimensional stability over a wide temperature range.
- Typical installations include walkways, platforms, and support frames, where the flat bar is exposed to weather, washdown, or chemical splashes.
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.
