FRP pultruded profiles are a new composite material made with fiberglass reinforcement as the base material, resin as the adhesive, and fiberglass cloth as the wrapping reinforcement layer; after full impregnation, the material is heated, formed, and cured in a metal mold and pulled by a pulling machine. With good physical properties, they are widely used in high-strength and long-span applications.

Applications:
Greenlogy TEC pultruded FRP structural profiles are widely used in various 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 service in areas where steel, aluminum or timber members have traditionally been specified. Today these profiles are often used in highly corrosive environments where stainless steel and other costly components were previously required.

Applications
FRP H-beams are commonly used in load-bearing structures requiring strength, corrosion resistance and electrical insulation, such as platform frames, walkway supports, cable trays, and beam and column members in corrosive environments including chemical, water treatment and marine applications. Their lightweight, high-strength characteristics suit long spans and applications requiring reduced maintenance. Contact us for detailed specifications and quotations.
Selection Guide
When selecting, evaluate span, load conditions, installation method and service environment together against the A×B×T1×T2 cross-section dimensions and unit weight. If you are unsure of the right specification, contact us and our technical team will help confirm detailed specifications and quotations.
Product Advantages
FRP H-beams are pultruded from glass fiber reinforcement and resin, offering lightweight, high strength, corrosion resistance, electrical insulation and ease of cutting and installation, which helps reduce later maintenance. Compared with traditional metal profiles, they are better suited to harsh environments such as damp, acid and alkaline conditions. Contact us for detailed specifications and quotations.
Inquiry
For information on FRP H-beam cross-section specifications, lengths, colors and matching connection solutions, please contact us and we will provide detailed specifications and quotations based on your project requirements. Please let us know your service environment and quantity so we can respond faster.
Service Environment
- These FRP H-beams are suitable for indoor and outdoor structural applications, where the glass fiber reinforced resin matrix resists water and moisture without the corrosion problems that affect steel.
- Typical service conditions include chemical plants, wastewater treatment facilities, cooling towers and coastal installations, where pultruded H-beams can withstand corrosive media, salt spray and industrial flue gas.
- Composite structures also perform normally under the temperature conditions commonly found in industrial processing areas, retaining their shape and load-bearing function where metal profiles may expand, rust or require frequent painting.
- For outdoor walkways, platforms and handrail frames, the UV-resistant resin system and non-conductive properties of H-beams help them operate reliably in wet and dry environments; please contact us to discuss your specific service conditions.
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.
