How much weight will Granite hold?
Keeping this in consideration, how far can granite span without support?
An unsupported span of 24” and up to a maximum of 36” is acceptable as long as the stone is supported on both sides of the span. Longer spans must be supported across the span. Over hangs should be not exceed 6” for 2cm granite, 10" for 3cm granite and 15" for 3cm quartz beyond the supported area.
One may also ask, how strong is a granite countertop?
Granite counters are heat resistant and can withstand the heat of hot pots and pans without damage. Impact from a heavy object may chip granite but heat from anything short of a blowtorch will not affect your countertop. Dark colored granite countertops are harder than light colored granites.
Granite is extremely unlikely to crack during normal use. Most cracks are the result of stress during handling, fabrication, or installation. However, it is possible to cause cracks or stress fractures by standing on countertops or, in some cases, placing extremely hot objects on the surface.
