Unfortunately there is no standard size for swimming pool overflow grating, all pools are designed differently using different sized grating.

Poly Advisory can manufacture bespoke grills to suit any width or thickness, straight or curved in a range of standard colours.

We are also able to offer a bespoke colour service manufactured to any RAL number subject to minimum order quantities. 

All grills are machined with 8mm slots, water tracks where necessary and with anti-slip hatching on the surface.
HDPE plastic is the most durable material available in a chlorinated swimming pool environment so will provide the longest lifespan possible. UV stabilised HDPE plastic is available on request.

Poly Advisory provide a survey and installation service if required.
