I bought several of these cut to 36 inches. These things are heavy! Obviously a quality product. The serrations were noticeable and pretty neat looking. One thing to keep in mind though, the bottom wasn't a shiny clean smooth surface, it was a bit scratched up, not a big deal but it's something to keep in mind.
Although this is a fairly small sink, a 4" section is capable of dissipating 45 watts with a temp increase of only about 25 degrees C ,in the horizontal plane, in a stagnant air area. With some air movement allowed, the temp rise was only about 15 degrees. This is going to be my "go to" heatsink in the future!
