Vollrath 3412 Centurion 12 1/2" Stainless Steel Fry Pan with Aluminum-Clad Bottom

The top diameter is the measurement across the frying pan from the interior of one side of the rim to the other. These dimensions are a close approximation as many frying pans have a curved upper rim, which makes precise measurement difficult. The standard naming is by top diameter, so although multiple brands have a 10” frying pan, there will likely be a small variation between each brand’s 10” pan.

A riveted handle is connected by small metal pieces (called rivets) that are crushed between the handle and the pan body to attach them together. This type of handle is more common on copper and aluminum cookware.

For a handle to be welded, the metal must first be melted and then adhered to the pan body. This creates a strong bond that leaves little to no space in between, so bacteria and other food crumbs can’t collect and cause sanitation issues. Both are long lasting solutions for fry and sauce pan handles because they are durable and can withstand heat.
