Tri ply stainless steel is a type of cookware made of three layers of metal sandwiched together. The three layers typically consist of an inner layer of stainless steel, a middle layer of aluminum, and an outer layer of stainless steel. The aluminum layer conducts and distributes heat very well, while the outer layer of magnetic stainless steel makes the cookware compatible with induction cooking, and the inner layer of surgical stainless steel ensures that the food has contact with only the highest grade of food-safe stainless steel. Tri ply stainless steel cookware is versatile, durable, and safe for cooking. It is also a good choice for those who are conscious about the safety and health aspects of their cooking. Tri ply cookware supports even heat distribution, making cooking easier, and burning of food while cooking is less compared to other types of cookware. Tri ply stainless steel cookware is not non-stick, but some manufacturers produce non-stick tri ply cookware with one layer, giving a non-stick finish. Tri ply stainless steel cookware is available in different ply, including 3-ply, 5-ply, and 7-ply. The difference between these types of ply is the number of bonded layers of metal, with 3-ply having three layers, 5-ply having five layers, and so on. Tri ply cookware is a good investment for those who want durable, versatile, and safe cookware that can last a lifetime.
