Thresholds in granite or other natural stones are those rectangular elements, offered in different thicknesses, which present the limit between the various rooms of a house or more clearly distinguish the inside from the outside.
They are offered in many materials, but the predominant choice is Natural Stone. Weatherproof, easy to clean and capable of withstanding continuous foot traffic.
The thresholds can be in different types of surface finish: glossy, smooth or with non-slip flamed and brushed finish.
The edges are normally beveled with any section to avoid chipping or dangerous edges, furthermore it is possible to create games with the different finishes, such as bush hammering, on the edges or on the upper surface.
