FRP and GRP pultruded profiles

FRP / GRP Pultruded Profiles

FRP and GRP pultruded profiles in Qatar Structural profiles are manufactured using a pultrusion process (polymerisation of a profile pulled through a heated die) and contain up to 70% fibreglass, ensuring exceptional mechanical strength. Their structure, composed of continuous directional glass fibres, gives them excellence resistance to impact and fatigue (overloading does not cause permanent deformations).

FRP (Fibre Reinforced Plastic) pultruded profiles have various advantages: extraordinary rigidity, corrosion resistance, electrical insulation and light weight. Designed by specialists in composite structures, pultruded profiles take into account all the properties required in a load-bearing profile or beam, such as longitudinal strength, shear resistance, flange flexural resistance and transversal strength.

applications for pultruded profiles and self-supporting structures, pultruded fibreglass profiles are designed to be used as structural supports with all the necessary performance guarantees.

Technical characteristics of Pultruded Profiles

Corrosion resistance: pultruded profiles normally use isophthalic resin, ensuring excellent resistance to corrosion. FRP (Fibre Reinforced Plastic) pultruded stabilise the resin against UV and add a corrosion-resistant barrier to the external surface. This barrier increases the volume of resin on the surface and avoids fibre blooming.

Examples of applications: all the small support systems normally made using traditional carpentry: platforms, walkways, landings, small supports, stands for chemical apparatus and instruments, insulating partitions, etc.

Light weight and insulation: a support using, pultruded profiles weighs about three times less than its equivalent in steel with the same rigidity. This leads to savings in transportation, handling and assembly and reduces costs for components that require frequent maintenance. Non-magnetic and non-conductive, pultruded profiles offer excellent electrical and thermal insulation.

Fibreglass nuts and bolts: threaded nuts and bolts in fibreglass-reinforced epoxy resin offer excellent mechanical strength and chemical resistance.
