Colours & shapes

Designers and engineers consider many factors when planning and building swimming pools. Design is important and safety even more so. The best effect is when the design flows seamlessly from wet to dry areas and we can help achieve that. We manufacture swimming pool overflow gratings in bespoke colours, shapes and sizes for your design.


Our overflow channel gratings are available standard in blue, white or black, and any RAL colour to your specification, so they can be colour matched to suit your decor.


  • Our swimming pool gratings are available in straight or curved design
  • Slots running at right angles or parallel to the pool edge for rectangular pools
  • Slots running at right angles for curved pools

Corner sections are available in 90° and 135° angles, or bespoke angles. Corners and joints are the most vulnerable part of your pool grating, so we manufacture strong, secure corners to the exact angle you require.

Safe and Hygienic

Swimming pool gratings have to offer maximum safety and hygiene and at the same time look good. Thanks to the special properties of the thermoplastic material High Molecular Weight Polyethylene (PE-HMW) our Polystone® D pool gratings meet these high requirements. They are:


Pool gratings made of Polystone® D conforms to Health & Safety guidelines DIN Standard 51097 red class C of Anti-slip Coefficient of Friction, a German standard that tests slip resistance of flooring in barefoot conditions using soapy water as a contaminant.


Polystone® D pool gratings do not crack, splinter, rot or delaminate. They are designed to meet the high safety requirements for swimming pools.

Easy to clean

Pool gratings made of Polystone® D require little maintenance. They are easy to clean with common cleaning agents and impervious to algae.

Corrosion resistant

Polystone® D overflow channel gratings are resistant to chlorine, sea water, cleaning agents, UV and weathering. Therefore they can be used for indoor and outdoor swimming pools.

Easy to handle - easy to install

With a density of 0.96 g/cm³ pool gratings made of Polystone® D are easy to handle and lighter than other conventional materials like stainless steel. This allows easy installation as well as easy removal when cleaning the overflow channel is necessary.
