What is Pultrusion?

Pultrusion is a manufacturing system for constant cross-section profiles, which allows obtaining any type of longitudinal profile with an excellent surface finish.

The basic process consists of pulling fibers (threads, rovings, mats), which are wetted with resin (isophthalic or vinylester) mixed with a catalyst. The material is then passed through a die at a specific temperature, which gives the final geometry of the profile and the finish of the final product.

Thanks to the uniform geometric characteristics of the cross-section, the resin, the fibers used, and their alignment and distribution, pultruded profiles are high-quality composite materials that compete perfectly with metal and aluminum profiles, both in terms of strength and weight respectively.
