Greenlogy TEC
FRP pultruded profiles are a new type of 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, 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 profiles are widely used in various applications, combining corrosion resistance, high strength, dimensional stability, and light weight, with thermal and electrical insulation properties. 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 where stainless steel and other expensive components were previously required.

Applications
Solid round rods combine high axial strength with corrosion resistance, and are commonly used in chemical platform guardrails, ladder rungs, cable supports and insulating equipment structures where high strength and rust resistance are required. To confirm suitability for a specific corrosive medium or load condition, please contact us for detailed specifications and a quotation.
Selection Guide
When selecting, first confirm the required diameter (metric or the corresponding imperial size), the length to be used and the type of load (tension, compression or bending), then match these with the installation method and connector type. Our technical team can help recommend specifications based on your operating conditions; contact us for detailed specifications and a quotation.
Product Advantages
This product is made of glass fiber reinforcement with a resin matrix, formed by pultrusion. It offers the typical composite properties of light weight and high strength, corrosion resistance, electrical insulation and low maintenance, and is suitable for replacing some metal rods to reduce long-term maintenance costs. Actual performance data depend on the specific specifications; contact us for detailed specifications and a quotation.
Inquiry Guidance
For commercial information such as dimensional tolerances, available lengths, surface condition and packaging, please provide the required specifications, quantity and delivery destination, and we will reply as soon as possible. Contact us for detailed specifications and a quotation.
Operating Environment
- The solid round rod is a pultruded FRP profile suitable for long-term indoor and outdoor use. As a structural component it resists atmospheric aging, and its appearance and service are not easily affected by sun and rain.
- In chemical, pharmaceutical, water and wastewater treatment and other environments with acid, alkali and salt corrosive media, the corrosion resistance of the solid round rod allows it to replace metal round rods as supports and connectors.
- The pultruded solid round rod provides electrical and thermal insulation and can be used as an insulating support rod in microelectronics, power and similar applications.
- The solid round rod is flame retardant and has a high strength-to-weight ratio, making it suitable for bridges and highways, transportation, metals and mining and other applications with requirements on component weight and safety; for selection in specific environments, please confirm cross-section dimensions and media conditions with us.
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.
