Manufacturing of fiberglass profiles.

Fiberglass – manufacturing through pultrusion.

Pultrusion is the main manufacturing method for our GRP profiles (glass fiber reinforced plastic). The process is continuous and highly precise, producing materials with high fiber content, consistent quality, and great design flexibility.
In pultrusion, reinforcing fibers (e.g. fiberglass rovings and fiberglass mats) are impregnated with a resin – such as polyester, vinyl ester, or epoxy – depending on the required chemical resistance and mechanical performance. After impregnation, the fibers are guided into a heated die that determines the exact shape of the profile. The profile is then cut to the required length.This method produces finished GRP products with high mechanical strength, corrosion resistance, and low weight – ideal for everything from industrial structures to infrastructure projects.

1. Glass fiber strands are pulled out and woven together into the correct composition of fibers.
2. The fibers are dipped in a bath of resin. This is where we can influence the properties of the material, such as chemical resistance, color and fire resistance.
3. The material composition is fed into finished molds where they are heated and cured to a solid profile.
4. The finished profile is then cut to the right length.
