GRP Moulded Grating

ll grigliato in PRFV - materiale Plastico Rinforzato con Fibre di Vetro – viene utilizzato per la costruzione di passerelle, scale, piattaforme, griglie di ventilazione, recinzioni, e in molte altre applicazioni dove è richiesta una superficie resistente agli agenti atmosferici, alla corrosione e all’usura.

GRP gratings

GRP gratings are particularly suitable for use in the presence of chemicals and in corrosive environments. They are non-magnetic and have high resistance to acids, UV radiation and fire. They are used for the construction of walkways, stairs, platforms, ventilation gratings, fences, and in many other applications where a surface resistant to corrosive liquids is required.

This type of grating, more commonly known as fibreglass grating, does not need surface treatments such as painting or galvanising, is lightweight, easy to install and requires minimal maintenance. The panels can be cut or drilled directly on site using the most common cutting tools. Thanks to their mechanical, physical and chemical properties, they have become an integral part of the construction and industrial sectors, offering an optimal combination of strength, durability and lightness.

Open Moulded GRP Grating | Production Process

Glass Fibre Reinforced Plastic, commonly referred to as GRP, is a composite material consisting of a polyester or vinylester matrix resin reinforced with glass fibre. Moulded GRP gratings are produced using an open, heated mould and a wet lay-up technique with the continuous addition of glass fibres, chemical additives and pigment. The components are inserted into the mould in alternating layers wetted with resin. At the end of the forming process, the gratings are cooled and then removed from the mould. This production method results in a grating characterised by high bi-directional mechanical strength, both transverse and longitudinal, as well as resistance to corrosion and chemicals. Other important characteristics of GRP grating are its light weight, about 50 per cent lighter than steel, and its dielectric property, i.e. to act as an insulator when current flows.
