GRP consists of glass fibres and polyester resins. The former ones, forming the structural part, ensure the product’s mechanical resistance; the latter are chemically durable and combine the various fibres; this allows stress distribution. ProMetall’s gratings and structures are produced with specially patented technologies that are mainly based on the concept of injection moulding (RTM) or pultrusion.
ProMetall gratings are also available with anti-slip surface, in accordance with DIN E 51130 (provisions concerning slip resistance), in the below versions:
ProMetall GRP-plastic gratings are produced in many different sizes, by means of injection moulding technology, to provide a quick solution for various system issues.
