GRP Moulded Gratings

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.


Accessories:

Applicable for our gratings we have special support angles which are concreted into the basement directly.
