Greenlogy TEC Structural Shapes: Pultruded FRP Profiles and Matching Fasteners

Common Sizes and Selection Tips for Structural Shapes

Greenlogy TEC structural shapes are produced by pultrusion, with glass fibers running continuously along the length of the profile. This gives good axial strength and stiffness, making the profiles well suited to beams, columns and bracing where loads act mainly along the axis. Surfaces can be smooth or gritted depending on the project, and installation is similar to steel sections using standard mechanical connections or matching FRP fasteners.

In practice, selection usually starts with the cross-section, the load requirement and the installation environment. Channels and angles are common in frames and bracing; I-beams, square tubes and round tubes suit longer-span beams and columns; flat sheets, toe plates and concrete embedment angles are often used on platforms, walkways and embedded locations. If the project has specific requirements for fire performance, chemical exposure or color, please state them in your inquiry.

• Cross-sections: channels, I-beams, angles, square tubes, round tubes, rods, flat sheets, toe plates, concrete embedment angles, threaded rods and nuts - these can be combined to suit drawings.
• Load direction: pultruded profiles are strongest along their length, so design members to carry axial tension or compression where possible and avoid long-term transverse impact.
• Connections and fastening: bolting, riveting or matching FRP fasteners can be used; hole positions and edge distances should follow the profile supplier's installation guidance.
• Environment fit: in damp, salt-spray or mildly acidic and alkaline conditions, FRP profiles are non-conductive, non-magnetic and do not need the frequent anti-corrosion maintenance of steel.
