Greenlogy TEC
FRP pultruded profiles are a new type of composite material made from glass fiber reinforcement as the raw material, 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 drawn out by a pulling machine. They have good physical properties and are widely used in high-strength, long-span applications.

Applications:
Greenlogy TEC pultruded fiberglass structural profiles from Greenlogy TEC are widely used in various scenarios, combining corrosion resistance, high strength, dimensional stability and light weight with thermal and electrical insulation. 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 costly components.

Application Scenarios
Isophthalic Y-shaped steel is suitable for corrosive environments such as chemical processing, marine and wastewater treatment, and is also commonly used in platforms, walkways, supports and other structures requiring high strength and long spans. Its corrosion resistance, light weight and high strength give it an advantage where conventional steel is prone to rust.
Selection Guidance
When selecting, please refer to the cross-sectional dimensions (A*B*T) and weight of the Y-shaped steel for a preliminary choice based on actual load requirements, span and installation method. For precise mechanical calculations or custom sizes, please contact us for detailed specifications and a quotation.
Product Advantages
Made with isophthalic resin and glass fiber reinforcement, it offers excellent corrosion resistance and durability, while being lightweight and high in strength, making transport and installation easy. Its smooth surface and low maintenance cost suit a wide range of industrial environments.

Operating Environment
- These pultruded FRP Y-shaped steel profiles are designed for outdoor structural applications such as FRP grating walkways, platforms and handrail frames, where the glass fiber reinforcement and resin matrix resist moisture and weathering.
- The isophthalic resin system makes the profile suitable for environments with corrosive media, including chemical plants, coastal areas and other damp industrial sites where steel sections require frequent recoating.
- Because the profile is a non-conductive composite, it is also often chosen for structural frames near electrical equipment and other areas where steel alternatives are unsuitable.
- For indoor installations, the same molded FRP Y-shaped steel can be used to build supports, stair treads and grating covers in wet or washdown areas; please contact us with your operating conditions to confirm the appropriate resin grade and full parameter list.
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.
