FRP-Molded-Grating

Install on the platform:
1. Support sides of Grating has a wide retainer of size 40mm on the girder, gap between each grating is 6mm. The installation gap of grating and concrete is 10mm.
2. Grating and support and girder should be fixed by fixture with the size of M or L. at least 4 fixtures for each grating. Two adjacent gratings should be connected by fixture with the size of C.
