GRP profile manufacturer – we offer ideal alternatives to traditional materials.

Plastic reinforced transversely with glass fibre mats offers innumerable benefits, including extremely high strength and high corrosion resistance. In addition, GRP profiles are electrically and thermally insulating, easy to process and have low weight. The weight-saving compared to steel is about 30%, allowing constructions to be developed that are many times lighter.

Profiles of glass fibre-reinforced plastic are used in many areas. In electrical engineering, medical technology and industry, among others, people trust in their outstanding properties and employ them on an ever-increasing scale.

Our GRP profiles are manufactured using the “pultrusion” process. By contrast with the extrusion process where the material is pushed through a die, the glass fibres are drawn here through a tank filled with resin. This enables efficient production and high flexibility.

And by the way – a speciality at IsoProfil is the combination of the best of two worlds: the combination of aluminium and plastic results in profiles that satisfy the highest demands even in the long term.
