GRP moulded gratings are also available with vinylester or phenolic resin. All kinds of resin are self-extinguishing and UV-stabilized.
Construction:
GRP gratings are produced by wet moulding and hot curing in a heated mould. The reinforcement consists of continuous fibreglass rovings in alternating layers, so the loads are distributed evenly in all directions.
Design:
Regularly moulded GRP gratings have a polyester resin matrix. Glass content is approximately 35%. Standard colours are green, yellow or grey, other colours are available according to RAL.
