Natura Vein Tech is a technology developed by Atlas Concorde that allows the typical veins of natural marble to be reproduced in porcelain stoneware slabs. Unlike traditional surfaces, the veining is not limited to the external part but runs through the entire thickness of the slab, creating visual continuity between the surface, edge and corners. This result, achieved thanks to an innovative production process, makes the marble effect more authentic and realistic, offering new design possibilities and natural elegance in every detail.
