GRP-Profiles

The GRP-Profiles are manufactured using the pultrusion process (from "to pull"). This production method is characterised by a continuous manufacturing process with a consistently high quality. The glass fibres are pulled through a guide head and then through a heated tool to reinforce the profiles. Here the fibres are impregnated with the resin mix and cured by heating to the desired geometry.

The profiles are manufactured in a continuous process and are cut to size directly after pultrusion. The standard lengths are 6.000 and 12.000 mm - other lengths are also possible depending on quantities.
