Greenlogy TEC
FRP pultruded profiles are made from glass fiber reinforcement as the raw material, resin as the adhesive, and glass fiber cloth as the wrapping reinforcement layer. After thorough impregnation, they are heated, formed and cured in a metal mold and pulled by a pulling machine to form a new type of composite material with good physical properties, widely used in high-strength and long-span applications.

Raw material introduction — resin types
Code | Resin type | Flame retardant performance | Recommended applications |
|---|---|---|---|
VEFR-25 | Vinyl ester type | Oxygen index 28 and above | Acid, alkali and other harsh corrosive environments |

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. Where steel, aluminum or wood components have traditionally been specified, durable Greenlogy TEC profiles deliver years of low-maintenance operation. Today these profiles are commonly used in highly corrosive applications that previously required stainless steel and other costly components.

Applications
Curved flat bars are commonly used in structural parts that require a curved profile or edge reinforcement, such as platform handrails, walkway frames, equipment supports and decorative trim. Their orthophthalic resin system suits general industrial and outdoor environments; weathering and corrosion resistance should be assessed against actual service conditions. Contact us for detailed recommendations.
Selection Guide
When selecting, consider the arc radius, cross-section dimensions, load requirements and installation method to ensure compatibility with adjacent components. You may provide drawings or service conditions, and our technical team will help recommend suitable specifications. Contact us for detailed specifications and quotations.
Product Advantages
This profile is made from glass fiber reinforcement and an orthophthalic resin system through a pultrusion process. It offers light weight, high strength, corrosion resistance and electrical insulation, and its curved design facilitates streamlined structures. Compared with traditional metal materials, it is easier to cut and install, helping to reduce long-term maintenance costs.
