Pultruded Fibreglass Grating is a composite of fibreglass reinforcements (fibres and mat) and a thermosetting resin system produced by the pultrusion process.
Pultruded composite grating has the most parts characteristics of molded composite grating, but the key difference is the brilliant fiber glass content (75%-78%), which will reduce the support strength and project charges under when being used under large span compared with molded composite grating,
