Pultruded FRP profiles are with the
constant cross-section structure by a continuous
pultrusion process using fiberglass reinforcements
with thermosetting resin matrixes. Pre-selected
reinforcement materials, such as fiberglass roving,
mat, woven fabrics or stitched fabric, are drawn
through a resin bath in which all materials are
thoroughly impregnated with a liquid thermosetting
resin. Typical resins included polyester, vinyl
esters and phenolic resin.
Any constant cross-section profiles can be pultruded.
Pultrusion allows the designer to customize the
selection of the resin system, the type and form
of fiberglass reinforcements, and the placement
of the reinforcements within the composite profile.
Typical pultruded profiles include FRP Angle, Square
Tube, I Beam, Channel, Round Rod, Round Tube, T
Beam, etc. They are widely used as handrail, support,
beam and other structure materials in the industries
of chemical, power, infrastructure, etc.
Pre-embedding style FRP
Frames are used to be pre-embedded in concrete as
frames for FRP grating,thus supplying sustainable
bases for FRP gratings fixed on trenches or pits.
