GDP KORAL s.r.o.

It´s a partnership of French company GDP SA, which are engaged in pultruded profiles and load-carrying constructions, and Czech company KORAL s. r. o., supplier of full range of materials and things for lamination. We are section of company GDP Group, which proposes, produces and supplies solutions on the basis of plastics composites by production plants in France, Spain and Czech Republic.


Technology of manufacturing

Plastics composites are produced by many various technologies. Company GDP KORAL is specialized in highvolume continual technologies, mainly pultrusion and pressing.

Electrical insulation

 The reinforced plastics composite profiles are widely used in electric engineering and power supply due to good electrical insulation as load-bearing structure and cabling, third rail coverboard, parts of transformer and switching station, plugs for electromotors, ladders.

 Advantages of reinforced plastics composites as electrical insulators are:

Dielectric properties:

We are able to produce a special conductive profiles by customer´s request by using of special resins as contrast to electrical insulation.

Available profiles:
