Square Hole Gratings

Hugely popular because the pattern is timeless and will fit into almost any scenario being sympathetic to even the most sensitive restoration project.  Larger gratings are especially useful used as walkways and pedestrian bridges over streams and water features. Properties include monasteries, theatres and period homes of all sizes in UK and especially in London.

These gratings are available in 3ft lengths (910mm) – if shorter lengths of the same width are required these may be available in the square hole made to measure grille range to compliment the full length grilles shown here.

Please email for advice if you have a particular length you require to cover and cannot find what you are looking for on this website. We have supplied hundreds of projects, restorations and new builds with these grilles to create walkways, drains, steps, pavement lightwells, threshold drainage, heating pipe covers and all manner of design schemes over the last ten years or more and would like to help find a solution if we can.

Square hole gratings available in a painted black finish, with the option of drilling and mesh for an additional cost, £50 for mesh and £15 for drilling.

The cast iron bearers shown in photograph are not included and are available separately, you can browse our bearers here.
