Manufacturing Process | Molded FRP Grating

Molding is the process of manufacturing by shaping liquid and pliable raw materials using a rigid, open and heated frame called a mold or matrix. By interweaving continuous glass fibers, which are thoroughly wetted with liquid resins, to desired dimensions, the continuous process produces an integral, one-piece construction. Finished molds are then allowed to harden (also known as curing). If the grating is to have embedded grit, the mold will receive the grit at this time before the panel is cured. Once curing is completed, the panel is extracted from the mold. The standard molded grating has concave top surface, and should a standard grit surface be specified, the grit would be bonded to the top of the panel at this time. Finally, The molds are cleaned and prepared for the process to begin.

This interwoven, one-piece construction product has bi-directional strength and due to high percentage of resin in molded fiberglass grating, it offers itself excellent corrosion resistance and optimal impact resistance.
