All our mixer bowls are made in the USA. Our stainless steel is the highest quality (No. 304: 16-gauge up to 60 quart and 14-gauge for the 80- to 140-quart sizes - with no seams to weaken them). This heavy-duty gauge steel results in a longer lasting bowl. All of our bowls that are larger than 20 quarts have a full support band around the entire diameter for added strength. Our 60-, 80-, and 140-quart bowls also have a bottom ring for added stability, strength, and bottom protection. All our bowls are fully guaranteed against defects for 12 months..
