Pultruded fibreglass grating is made by the process of pultrusion, which pulls the glass strands through a machine and wraps in a glass fabric, then seals together with a resin. It is manufactured by assembling two structural fibreglass shapes (cross and bearing bars) into a grid pattern, which increases the support and stability of the grating under extreme loads.
With its much higher glass content, pultruded fibreglass grating has unidirectional strength, resulting in greater span capability than molded fibreglass grating. This makes it spec
