Company history



We are a joint venture of the French company GDP SA, which deals with the production of pultruded composite profiles and load-bearing structures, and the Czech company KORAL s. r. o., a supplier of a complete range of materials and equipment for FRP lamination.

Within the group, we have 26 production lines in production plants in Tišnov (Czech Republic) and Montendre (France). In both production plants, continuous production takes place 24/7.

The beginnings of pultrusion production in Tišnov dates back to the 1960s. At that time, production was focused exclusively on the needs of the army. Army projects were subsequently replaced by the production of laminates as ski reinforcements.

In 1992, during the privatization of the former state-owned company, the company KORAL, s. r. o. was established, which continued production of ski laminates.
