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

Applications:
Greenlogy TEC pultruded FRP profiles are widely used in various scenarios, combining corrosion resistance, high strength, dimensional stability and light weight, with thermal insulation and electrical insulation properties. Durable Greenlogy TEC profiles deliver years of low-maintenance service in applications where steel, aluminum or wood components have traditionally been specified. Today, these profiles are often used in highly corrosive applications that would otherwise require stainless steel and other costly components.

Application scenarios
Structural Profile - H Beam (Isophthalic) is suitable for applications with high requirements for corrosion resistance and strength, such as chemical platforms, wastewater treatment facilities, marine engineering, bridge walkways and long-span support structures. Its lightweight, high-strength characteristics reduce the load on support structures and facilitate installation and maintenance.
Selection Guide
When selecting, clarify the span, load conditions and service environment, and choose the appropriate cross-section size based on the existing specification table. If custom cross-sections or special lengths are required, please contact us for detailed specifications and quotations.
Product Advantages
The isophthalic resin system gives the product excellent corrosion resistance and water resistance, while glass fiber reinforcement ensures high strength and stiffness. The product is also lightweight, insulating, non-magnetic and long-lasting, making it suitable as a replacement for traditional metal profiles.
Inquiry Guidance
For detailed specifications, technical parameters or bulk purchase terms for Structural Profile - H Beam (Isophthalic), please contact us for detailed specifications and quotations. We will provide professional advice based on your needs.
Service Environment
- This pultruded FRP H-beam is manufactured based on an isophthalic acid resin system, making the profile suitable for continuous use in outdoor and humid industrial environments where weak acids, weak bases and salt spray are present.
- Glass fiber reinforcement and the isophthalic acid resin matrix enable this Structural Profile - H Beam (Isophthalic) to be used in chemical plants, wastewater treatment areas and coastal facilities, where steel requires frequent recoating or replacement.
- Because the profile is non-conductive and corrosion-resistant, it is commonly selected for indoor and outdoor structural frames, platforms and support beams exposed to weather, moisture and process spills.
- For applications involving concentrated chemicals, high temperatures or sustained loads at elevated temperatures, please contact us with the specific media and service conditions so that the correct resin grade and profile specification can be confirmed.
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.
