Material Quality

There is a material best suited for each use case. Once the material is identified, we work closely with the world’s leading steel mills for procurement. Material quality is an issue of paramount importance; for this reason, we own the internationally recognized ALCO brand, with which we unequivocally identify the quality of the steels used and conduct a quality control of incoming materials.
