Cast Stone Keystones

Cast stone keystones are a versatile product that can be used on their own and with cast stone lintels. They are a trapezoid shaped product that can add a very subtle touch of class to a building, often as a central point above a window opening. They are hugely popular with builders and are usable with rendered properties as well.

KS Type Keystones

KS Type keystones are standard cast stone keystones. They are available in six standard shapes ranging from 215 x 140mm up to 221 x 310mm. Bespoke sizes can be manufactured as well. All of our keystones are available in four colours – Bath, York, Cotswold and Portland.
