Featuring an exceptional 3-ply construction with an impact-resistant 3004 aluminum alloy core, this versatile item is built for enhanced performance. While the aluminum core expands throughout the entire pan, eliminating hot spots to provide even heating on both the sides and bottom of the pan, its non-reactive 18-8 stainless steel interior guarantees flavor neutrality. The pan is also topped with a strong 18-0 stainless steel exterior to stand up to punishing commercial kitchen conditions, which makes it suitable for use on gas, electric, and induction ranges.
