GRP constructions offer considerable corrosion advantages over metal and are therefore much more economical over their entire life cycle. Due to their easy machinability, adaptations can be carried out easily and effectively on site. Due to the low weight, assembly can often be carried out purely manually, without a crane or other lifting equipment. Handling at great heights is therefore much easier. Typical applications are catwalks, bridge constructions and bridge decks, chemical plants, cooling towers, water treatment plants as well as oil and gas plants.
