Greenlogy TEC
FRP pultruded profiles are a new type of composite material made with glass fiber reinforcement as the base, resin as the binder, and glass fiber cloth as the covering reinforcement layer; after full impregnation, they are heated, formed and cured in a metal mold and drawn by a pulling machine. They have good physical properties and are widely used in high-strength, long-span applications.

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, along with thermal and electrical insulation. Durable Greenlogy TEC profiles provide years of low-maintenance service in areas where steel, aluminum or wood components have traditionally been specified. Today, these profiles are often used in highly corrosive applications that previously required stainless steel and other costly components.

Application Scenarios
Vinyl H-beams are suitable for applications that require both corrosion resistance and structural strength, such as load-bearing and support structures in chemical processing, water treatment, marine engineering, offshore platforms and various corrosive environments. Their long-span, high-strength characteristics also make them suitable for platform walkways, equipment supports and frame systems. For suitability under specific operating conditions, please contact us to evaluate based on your actual service conditions.
Selection Guide
When selecting, first confirm the cross-section dimensions (A*B*T1*T2), span, load-bearing method and the corrosiveness of the medium, then determine the connection and fixing scheme based on installation conditions. Different cross-section specifications differ in stiffness and dead weight, and must be matched to the actual load conditions. If you need calculation recommendations and specification comparisons, please contact us for detailed specifications and quotations.
Product Advantages
The product uses fiberglass as reinforcement and resin as matrix, and is formed by impregnation, heated compression molding and curing, and pultrusion, offering good physical properties and stable cross-section consistency. The vinyl system performs notably well in corrosion resistance, and also features light weight, high strength, and ease of cutting, machining and on-site installation. Compared with traditional metal profiles, it is more suitable for long-term use in humid and corrosive environments.
Inquiry Guidance
For commercial information on vinyl H-beams such as specifications, dimensional tolerances, colors, surface treatment, and packaging and transportation, please contact us. Please provide the required cross-section, quantity and service environment, and we will provide detailed specifications and quotations accordingly, and assist in confirming the delivery plan.
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.
