MOLDED GRATING MANUFACTURING PROCESS

Molding is the process of manufacturing by shaping liquid and pliable raw material using a rigid frame called a mold or matrix. Panels are manufactured in an open, heated mold, by interweaving continuous, thoroughly wetted, fiberglass rovings with liquid resins.

• Liquid resin and continuous glass rovings are systematically layered in the mold, manually, to desired dimensions and thickness.
• Finished molds are then allowed to harden, which is known as curing.
• Once curing is complete, the panel is ejected from the mold.
• Secondary applications, such as post applied grit, can now be bonded to the concave top surface.

Interwoven, one piece construction, produces a product that has bi-directional strength and optimal corrosion resistance, with no mechanical joints between bearing bars, distributing loads throughout the panel section and around cut-outs.
