Corners have always had a central role in loadbearing stone walls, being of considerable importance for the overall stability of the structure. Stones of particular size and shape were used for this purpose, and worked further if necessary. There are different corner stones depending on the area and type of construction.

GeoCorner SQUADRATO angle bar (P40) is obtained from a type of soft stone used in some areas of the Mediterranean. It is cut using a saw and finished using a bush hammer to create a uniform surface. As a stone corner cladding, it can be combined with any finish and numerous stone models, by selecting a colour to match the manufactured stone veneer corner with the colour of the wall.
