FRP pultruded profiles are made from fiberglass reinforcement as the raw material and resin as the binder, with fiberglass cloth as the covering reinforcement layer. After thorough impregnation, the material is heated, formed, and cured in a metal mold and then pulled by a haul-off machine. This new type of composite material has good physical properties and is widely used in high-strength, long-span applications.

Applications:
Greenlogy TEC pultruded FRP profiles, supplied by Greenlogy TEC, are widely used in various applications and combine 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 are traditionally specified. Today these profiles are often used in highly corrosive applications that previously required stainless steel and other costly components.

Application Scenarios
Y-shaped steel (orthophthalic) is commonly used for load-bearing and connection parts that require strength and span, such as platform supports, frame nodes, handrail skeletons and structural components in corrosive environments such as chemical and water treatment. Its orthophthalic resin system is suitable for general anti-corrosion and outdoor use; please contact us to confirm suitability for specific scenarios.
Selection Guide
When selecting, first confirm the load form, connection method and installation space, then match the existing structural design according to the A*B*T cross-section dimensions and unit weight. Similar specifications in the table can be substituted on the principle of equal strength or equal stiffness. As working conditions vary greatly, we recommend providing us with the load, span and corrosion conditions so that our technical staff can assist in recommending suitable specifications.
Product Advantages
This profile uses glass fiber reinforcement and a resin matrix, formed by molding and pultrusion. It has the typical composite characteristics of light weight, high strength, corrosion resistance, insulation and non-magnetism, and is suitable for replacing some metal profiles to reduce dead weight and lower maintenance frequency. The surface maintains good appearance consistency and is easy to cut and drill.
Inquiry Guide
For detailed specifications, length options, packaging methods and commercial terms of Y-shaped steel (orthophthalic), please contact us for detailed specifications and a quotation. Please provide the required cross-section dimensions, quantity and operating environment, and we will reply promptly.
Operating Environment
- Y-shaped FRP structural profiles are suitable for indoor and outdoor installation. Their glass fiber reinforcement and resin matrix resist moisture and weathering, without the corrosion risk of untreated metal profiles.
- Pultruded FRP structures can be used continuously in humid, salt-laden or chemically corrosive atmospheres, which are typical environments in chemical plants, water treatment plants and coastal projects, where Y-shaped profiles serve as load-bearing or support components.
- Because the profile is heated and cured in a metal mold and pulled out by a pulling machine, the finished Y-shaped steel maintains its dimensional stability within the normal temperature fluctuations of industrial use (from cold outdoor sites to warm plant interiors).
- For specific chemical exposure, UV load or temperature limits, please contact Greenlogy TEC and provide your project conditions; we will confirm applicability against the complete parameter table.
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.
