                                                                                               Pultruded FRP Beam I

General Introduction
Pultruded FRP beam I are manufactured from glass reinforced isophthalic polyester resin with E glass fibre, suitable for heavily industrial applications due to their extremely high load bearing capabilities. Sold in 6 metre lengths.

FRP/GRP beams have excellent bearing capacity and they are widely used in bridges, roof bracing structures and industrial platforms.

Pultrusion Technique
Pultrusion is a continuous process using fiber reinforcements with thermosetting resin matrices. Pre-selected reinforcement materials, such as fiberglass roving, mat, woven fabrics or stitched fabric, are drawn through a resin bath in which all material is thorougly impregnated with a liquid thermosetting resin. Typical resins include polyesters, vinyl esters and phenolics. The wet-out fiber is formed to the desired geometric shape and pulled into a heated steel die. Once inside the die, the resin cure is initiated by controlling precise elevated temperature. The laminate solidifies in the exact cavity shape of the die, as it is continuously pulled by the pultrusion machine. Most any constant cross-section part can be pultruded.

Pultrusion Process 

  • Beam structure of bridge.

  • Roof support structure.

  • Industrial platform.

  • FRP/GRP beam support stair.

  • Cooling tower structure.

  • Variety of cable management systems and support.

  • Grating structure component.

  • Platforms and walkways where non electrical and thermal insulating properties are required.
