Greenlogy TEC
FRP profiles are made from glass fiber reinforcing material, 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 pultruded under the pull of a traction machine. This new composite material has good physical properties and is widely used in high-strength, long-span applications.

Application scope:
Greenlogy TEC pultruded FRP structural profiles from Greenlogy TEC cover a wide range of applications and combine 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 specified. Today these profiles are often used in highly corrosive applications that previously required stainless steel and other expensive components.

Applications
As a structural profile, the seven-hole hollow profile is suitable for market sectors such as construction, bridges and highways, chemicals, food and beverage, manufacturing, metals and mining, and microelectronics, and can be used for platforms, walkways, support structures, and similar applications. When selecting for a specific scenario, load and environmental conditions must be taken into account; you are welcome to contact us for detailed application advice.
Selection Guidance
During selection, factors such as load requirements, span, support conditions, corrosive environment, and installation method must be considered. We recommend providing operating parameters so that our technical team can assist in recommending suitable specifications. You are welcome to contact us for detailed selection support.
Product Advantages
This profile is made of glass fiber reinforced material and a resin matrix, formed through the pultrusion process. It features light weight, high strength, corrosion resistance, and electrical insulation, and is suitable for high-strength, long-span applications. Compared with traditional materials, it can extend service life and reduce maintenance costs under specific environments.
Inquiry Guidance
For information such as detailed specifications, dimensions, weight, price, minimum order quantity, and delivery time, you are welcome to contact us. Please provide your specific requirements, and we will reply as soon as possible and provide professional support.
Operating Environment
- This seven-hole hollow profile is made of glass fiber reinforced material, with resin as the binder and a glass fiber cloth wrapping reinforcement layer, and is suitable for indoor and outdoor installation environments where moisture and atmospheric exposure exist.
- Because the pultruded structure combines glass fiber reinforced material with resin, this profile is used in environments where corrosive media and humidity are common, such as chemicals, food and beverage, manufacturing, metals and mining, and microelectronics.
- The hollow seven-hole cross-section reduces weight while maintaining structural rigidity, so this profile is selected for high-strength, long-span applications in construction, bridges and highways, and industrial environments.
- For specific temperature ranges, chemical corrosion resistance grades, and other operating conditions, please contact Greenlogy TEC and provide your application details.
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.
