Steel Grey Porcelain 40mm Downstand Coping Stones

Do you ever feel something is missing from your garden design - something that would give it the look of a fully finished garden? Wall coping stones may be the answer. Grey is a perennially popular choice for hard landscaping and, part of our range of mid-grey porcelains, Steel Grey Wall Coping Stones, with a 40mm downstand, are also available in matching step treads. Use treads and coping, with their matching edge profile, to unite your garden in a coherent design. We recommend that all customers read our product & installation guides before buying.

Porcelain is manufactured in batches and therefore the colour and texture may vary from batch to batch.

This may mean that the porcelain you receive when ordered may differ from the samples or showroom displays viewed before purchasing.

Different sizes are manufactured in different batches. It is therefore not recommended to mix sizes.

If you feel this may be a concern for you, please contact our sales team who will be happy to advise you accordingly.

We recommend keeping a record of the 'batch colour code' of the delivered porcelain in case further stock is required. This can be found on the box that the porcelain is packaged in, and it is usually a number followed by a letter, or a six digit number.
