G341 Cheapest Grey Granite From North China Dawei Stone.

Granite is the premier material for steps and landings, for several reasons:as a natural stone, it doesn’t hold water (unlike concrete)
properly installed granite is set dry, without any mortar, so there is nothing to come apart through the winter freeze/thaw cycle
it’s so heavy, it will remain in place forever if properly installed

seven-inch thick granite is non-skid, wear-resistant, and immune to damage from de-icer
indigenous to New England, granite is inherently beautiful
qualifies for LEED credits since it is a local material quarried in Barre, VT
