How much granite overhang without support is OK?
Comments (13)We have a 60" long x 18" wide overhang with our island. Our granite guy said we didn't need to support it, but I beg to differ and supported it just in case. We drilled a 3/4" plywood sheet (just smaller than the entire island)into the top of the cabinets and then routed in 1/2" steel bars (these were also just smaller than the island) and drilled these into the plywood. The granite was laid on top (and glued/epoxied). Although you can't see the plywood unlesss you bend over or are sitting under the overhang, we chose to cover the edges of the plywood with thin strips of wood that matches our cabinets, so it looks like the support extends as part of the cabinets. We did all this because we wanted a clean look with no corbels, etc. It is great (I had to stand on the island to change a light bulb) and I am very happy that I chose to support it...now I don't have to worry!...See MoreNeet help on 12' granite overhang support on kitchen island
Comments (13)I know this is not going to help the original questioner posted in 2007 and I sure wish I had found this question back then... But for those of you looking for "THE" answer... hear you go. The Amastin Company, Corryton TN, has been providing steel support bars in supporting hard surface counters to the East TN market since 1995. In this particular case, which is a common one, Amastin offers a 31" long x 2-1/2" wide x 1/2" thick steel support bar that would bump and mount into the back of the front face frame, notch and recess flush across the back cabinet mounting strip. This support would overhang 8" leaving it approx 4" from the counter edge making it virtually hidden. Amastin has the overhang support thing figured out and if you have any questions or in need of custom support advise... Amastin is place to find the answers.

Comments (13)ni 2006: As far as the assembly that you are proposing goes, here's my suggestions: Here's what the Marble Institute of America's Technical Design Manual says (pretty much THE BIBLE for the Stone Industry): 1. ANY unsupported span of 3CM slab greater than 10" needs to have corbels or a structurally sound mechanism for support. 3. Plywood alone will not be sufficient in this application. Here's a question for you - are you going to have a thicker laminated edge at the perimeter if the island? Like a 6CM edge detail? If so, you could use 1" x 1" angle iron or box stock epoxied to the underside of the stone to help support the overhang... just a thought - it works pretty good in unique design situations like the one you're proposing.... ALSO - is that column going in AFTER the stone, or is is already there? IF it's already there, you'll probably have to have a seam to accomadate getting the stone around the column... let us know on these details - it will help making some more accurate suggestions kevin Kevin M.

Comments (11)The plywood is put on before templating and cut to be flush with the cabinets on the side without seating overhang and extending about an inch or two less than you want the overhang on the overhang sides. The templater than measures the plywood and the granite top is made to fit. At least that is how it was done for us. Our steel bars are about 2" wide and 1/2" thick. The steel bars can't crisscross. There isn't enough thickness of the plywood for that. To support an overhang on two sides, the steel bars could run at angles so that they radiate from the corner opposite the overhangs. Our bars were angled to avoid the prep sink and range top cut outs. Our bars are long enough to run all across the top of the island. Our granite has a laminated edge that hides the edge of the plywood. I have friends who don't have a laminated edge who used a piece of molding stained to match their cabinets to cover the plywood edge. The bottom of our plywood is unfinished. I wish I had thought to ask our GC to use one with cherry veneer facing down and stained to match our cabinets. Nobody but me notices it....See More2LittleFishies
