Granite tiles and floors are the most popular and base products.
Comparing with marbles, they are cut from small slabs, so the prices mostly are cheaper than big random slabs.
Since granites are with very small color variation, mostly it is no necessary to put the tiles on the ground to select the color.
The sizes can be 305X305X10mm, 457X457X10mm, 600X600X20/30/40mm etc.
