Molded Grating
FRP molded grating is made of vertical and horizontal continuous fiberglass fully soaked in unsaturated polyester resin giving perfect bi-directional mechanical properties. Combining the lasting non-slip properties, the resilience to corrosion and the proven long term cost advantages, molded gratings provide the ultimate in reliable performance. Besides it is easy to cut and install. Weenoor offer the widest selection with panel sizes ,colors and slip resistant surfaces, you can avail FRP Gratings suiting your specific requirements.
