Profiles made of GRP composite – glass fibre reinforced plastics - are a modern-day alternative to conventional building materials like concrete, aluminium, steel and wood.

GRP has the advantage of combining a number of properties not normally all found in a single material. In particular, GRP is notable for its strength, low weight and resistance to corrosion.

The corrosion-resistance of GRP makes this material ideal for railings on cooling towers where the profiles are continuously exposed to the action of water.
