Molded grating process
Molded grating is manufactured by laying continuous glass fibers in the mold in the direction of vertical and horizontal, and thoroughly wetted out with resin, layer by layer. When the weaving process is completed, the mold is heated to cure the panel. After curing, the panel is ejected from the mold. The standard panel would have meniscus (concave) top surface. Any process such as post applied grit could be bonded after as a secondary operation. This continuous process produces an integral, one piece panel, which offers excellent corrosion resistance as well as bi-directional strength.
Excellent properties
1) corrosion/slip resistant 2) fire/impact retardant 3) high strength-to-weight ratio 4) easy to install and to maintain
