W Clip

Gratemetal provides W Clip of two types, namely Dome washer clip & Recessed washer clip for securing a wide range of FRP Grating types & sizes. Our W clips can be used with standard square & rectangle mesh gratings as well as with Mini & Micro mesh grating profiles. W clips are also a great match for holding down fiberglass grit plates, checkered plates and covered fiberglass grating. W clips can be used in conjunction with Gratemetal bottom clamps when you cant access to the bottom of the grating floor. 


1. Dome washer clip:  The round dome washer clips can be fixed directly to the substrate. Its dome shape design & recessed centre that allows the bolt to sit flush with it helps in reducing trip hazards. The larger surface area of dome washer clip offers better stability & superior holding capacity for a longer period of time and is therefore suitable in areas of heavy loads & regular passage of vehicles.

2. Recessed washer clipThe round recessed washer clip offers a flush surface design which can be directly fixed to the substrate. These round recessed washer clips are medium-duty clips and are recommended in areas where movement is restricted to the pedestrians only.

Assembly & Installation: W Clip is supplied with suitable countersunk cross-head bolt also called as CSK Philips bolt, nut & washer for fixing FRP gratings directly to the substrate. The length of the bolt corresponds with the height of the grating panel being secured.
