Satin-finished with a high-gloss polished, reinforced edge. Stable, multiple spot-welded handles that do not absorb heat. Acid-resistant. The sandwich base (stainless steel, aluminum, stainless steel) combines the heat distribution advantages of aluminum with the durability and magnetic benefits of stainless steel, allowing for induction cooking as well. The base is applied using Impact Bonding Technology, meaning it is pressed across the entire pot surface and seamlessly welded. This guarantees optimal heat distribution and maximum protection against corrosion. We offer a 10-year warranty on material, construction, and manufacturing defects for Profi Line pots and pans. Damage due to improper use, accidents, and wear from daily use is excluded from the warranty.
