Granite needs to be supported. Granite, a brittle stone can snap under it’s own weight and indeed might require countertop support brackets. These support brackets are used like steel support beams under the heavy granite, keeping the beautiful stone from shattering to the floor.
The granite countertop support brackets are spread across the underside of the overhang every 16 inches. No closer then what you would find the default spread of wall studs.
Use countertop brackets when overhanging granite beyond 7 inches past the support structure. Since granite overhangs can weigh in at hundreds of pounds, you must factor in and take into consideration how fragile granite countertops are. The granite support brackets are necessary if you plan on extending the granite past that 7-inch mark. It’s a matter of safety due to the extrema weight and sharp force created when granite snaps and crashes to the floor. Granite supports brackets can be either efficient, ornamental, or both depending on your granite countertop installation.
Now unlike man made materials like Dupont Corian, LG Hi Macs, Formica, Wilsonart, Staron and LivingSton countertops a natural stone sliced into a slab, taken from the earth and put in your kitchen it’s going to need support. All-natural stone countertops require some planning and consideration of how to protect it and those enjoying it in your home.
