Is there a big difference (other than price) between an 18 gauge vs 16 gauge stainless steel sink? Are scratches easier to buff out of a 16 gauge sink?
Also, anyone have any experience with Ticor stainless steel sinks?
The heavier gauge (lower number) means that the metal is thicker. It should be harder to dent if you dropped something. Scratches...that would depend on the alloy - not all SS alloys are the same. It takes a lot more work to bend heavier gauge metal into the desired shape, but it also means that there's more metal thickness where it gets stretched most therefore it's stronger. A deep sink may require heavier gauge so there's enough metal once it is shaped. A heavier gauge sink may end up being quieter (won't ring as much) when used with a garbage disposer.
