16 is commonly used in zero and half radius sinks because the thicker steel is needed when the shapes are not stamped out. Either is wonderful providing the grade of the steel itself is high quality.
The percentage of nickel and chromium determines corrosion resistance. The higher the percentage, the better the grade of stainless. 304 grade stainless is comprised of 18% chrome and 10% nickel.
Look for "Certified" 304 Stainless Steel.
