From the almost inexhaustible amount of aggregates, in METTEN Stein+Design's laboratory will be selected by strict quality criteria the colored natural sands and natural stone chippings, from which METTEN´s concrete stones consists of. The specific properties of these materials perfectly complement each other in complex recipes with the top-quality of METTEN stones.
The several manufacturing processes have been developed for generations in the company and are partly internationally patented. With the quality control system MQ 1, we have established our own quality standard, which goes beyond the European quality standards.
We produce concrete blocks with a variety of functional advantages, a high durability and timeless design.
Carefully selected natural stone chippings like granite, basalt or porphyry, high quality natural sands and special finishing processes give Metten concrete blocks its unique effect.
Quality assurance through exact process technology and controls.
Colored natural sands and high-quality pigments guarantee best colour resistance.
