The most common material for natural stone stairs is granite. Because of its hardness and durability, the granite is the most requested material, because the stairs are one of the most stressed parts of the building and they are also more exacting on maintenance and restoration. Our limits on the realization of granite stairs do not end with normally geometric shapes, but we can create any shape of a staircase, pleasing to the eye of an investor and an architect. We create, on request, a non-slip strip by sandblasting on ascending area and thereby reducing the risk of slipping.
