If you need to cut the GRP product, a good quality abrasive disc, jigsaw or hacksaw can be used. The GRP material is quite tough to cut by hand, so if power tools are not readily available, please ask about our cut to size service. If appearance is critical we recommend the application of a small trial area first. 


This is either laid into a frame or fixed to an existing gantry etc. We supply suitable Fixings – please see the Description tab. There are many different ways to fix the grating to the substrate.

If you have purchased grating clips from us, you should use the following information as a guide: 

‘M’ and ‘L’ Clips: Set out where you will position each grating clip, a guide would be one in each corner and then every 500mm. Push the clips into the open mesh squares so that the clip sits neatly on the load bar(s) and the clip’s base is sitting close to the bottom of the grating panel. If you are fixing directly on the existing surface, drill a pilot hole through the clip and into the substrate then fix using the appropriate screw and plug. If you are fixing into a support frame you will need to drill through the frame and then use a bolt fitting and tighten the washer and nut underneath the frame.
‘C’ Clips: Set out where you will position the grating clips, a guide would be one in each corner and then every 500mm. Join the two grating panels together and then slot over the ‘C’ clip and twist in place, simply tightening the bolt and nut.
Please note that Watco GRP Grating is more difficult to cut on site than other GRP items – remember, we cut to size at no additional charge.
