GRP profile gratings:

GRP profile gratings are also available with Isophthalic polyester, vinylester or phenolic resin. All kinds of resin can be added with the fire retardant and UV against materials.

Construction:
GRP profile gratings are based upon I-beams, T-bar etc. 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. If requested the surface can be gritted,plain,covered or diamond surface.
