Triwall Composite Steel Plate Pan - 4-Layer Copper-Clad Cookware Blanks
MESCO fabricates tri-wall composite steel plate for cookware blanks and OEM pans: a 0.6 mm brushed stainless steel cooking surface, a full-width 1.5 mm aluminium thermocore, a 0.4 mm polished copper outer wall and a 0.5 mm S/S 430 magnetic base. Each layer is bonded into a single warp-resistant body, so one plate delivers the cooking response of copper, the evenness of aluminium and the durability of stainless steel. Non-reactive with acidic foods, resistant to metal utensils and easy to deglaze - a professional cooking surface that stays clean. A full-width aluminium core that absorbs heat quickly and spreads it evenly across base and sidewalls, eliminating hot spots. Copper responds almost instantly to burner changes, so pan temperature follows the flame in real time for precise control. A magnetic stainless base that makes the finished pan induction-ready while keeping the exterior non-reactive. Yes. MESCO adjusts each metal layer within the composite plate and the finished blank diameter to match your OEM specification. Share your target weight, size and cooktop requirements with our sales team. Type 430 stainless is magnetic, which is what makes the finished pan work on induction cooktops without a separate adapter disc. It also protects the copper wall from scratches on storage racks. Aluminium stores and spreads heat faster than steel alone. A full-width core raises the whole base to cooking temperature quickly and holds it steady, reducing scorched sauces and uneven browning.
