A Brief Introduction

Fiberglass Reinforced Plastic (FRP) is a plank material material cured in the matrix of unsatuaread resins including isophthalic, orthorphthalic, vinyl ester and phenolic, with reinforced frame of fiberglass roving through a special production process, with a certain rate of open meshes.

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.
Surface:As a standard moulded GRP gratings have a concave surface, which provides anti-skid properties R13. If requested the surface can be gritted,plain,covered or diamond surface.
