Greenlogy TEC
FRP pultruded profiles are made with glass fiber reinforcement as the base material, resin as the binder, and glass fiber cloth as the covering reinforcement layer. After thorough impregnation, they are heated, shaped, and cured in a metal mold and then pulled by a traction machine. This new type of composite material has good physical properties and is widely used in high-strength, long-span applications.

Applications:
Greenlogy TEC pultruded FRP profiles from Greenlogy TEC are widely used in many applications, offering a unique combination of corrosion resistance, high strength, dimensional stability and light weight, together with thermal insulation and electrical insulation properties. Durable Greenlogy TEC profiles provide many 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 costly components.

Application Scenarios
Hollow-core structural profiles are suitable for industrial platforms, walkways, handrails, support structures and equipment frames that require high strength, long spans and corrosion resistance. Their light weight and high strength also make them a common choice for renovation projects that need reduced dead load or fast installation. Contact us and we will recommend suitable specifications based on your specific working conditions.
Selection Guide
When selecting, please consider factors such as load requirements, span, service environment (e.g. corrosive media, temperature) and installation method. You may provide cross-section dimensions, length and quantity, and we will help you match suitable profile specifications. Contact us for detailed specifications and a quotation.

Service Environment
- This hollow-core profile uses vinyl resin and is suitable for indoor and outdoor installations where moisture and water vapor are present.
- The vinyl resin matrix resists corrosive media, making this hollow-core profile suitable for chemical, wastewater and coastal environments where steel tends to deteriorate.
- Because the profile is made from glass fiber reinforcement combined with vinyl resin, it maintains structural integrity under various ambient temperatures without becoming brittle or losing shape.
- Typical locations of use include industrial plants, walkways, platforms and structural frames exposed long-term to weather, salt spray or process chemicals.
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.
