Fiberglass Structural Profiles

GRP/FRP Structural pultruded profiles is manufactured using a resin matrix combined with a fiber reinforcement. This is continuously produced and cured to provide a material with exceptional strength and resilience. GRP/FRP structural profiles offer a number of advantages and mechanical qualities that are comparable to or better than steel equivalents. The structural profiles are available in various shapes like C/U Channel, I-Beam, H-Beam, Round Tube, Square Box, Angle, Rod, Hand Rail, Deck panels, etc and customized shapes are also available upon request.
