Weight A 1 Â½ inch thick countertop made of standard concrete has an approximate weight of 18.75 pounds per square foot. (Granite is approximately 18 pounds per square foot.) Standard cabinetry will typically support this weight because itâs distributed over a large area.
All the standard edges are 3 cm thick. This is the standard size for granite slabs. Two cm is not safe for kitchen countertops, and any slabs thicker than 3 cm are much more expensive. [CLICK HERE to visit our Houzz.com profile for hundred more pictures of granite edges and designs.]
