GRP profile gratings
GRP profile gratings are also available with vinylester or phenolic resin. All kinds of resin are self-extinguishing and with UV-stabilizer.
Construction:
GRP profile gratings are based upon I-beams in load-bearing direction, which are connected by rods and distance tubes. They are glued together torsion-free.
Design:
Standard GRP profile gratings are made from isophthalic polyester resin. The reinforcement is achieved by a combination of fibreglass mats and rovings reaching a glass content of approximately 65%. Standard colours are grey or yellow, other colours according to RAL are available.
Surface:
GRP profile gratings have grooved anti-skid surface. If required, gritted surfaces are available, which fulfil the German anti-skid standard R13.
