Shubham, Are you opening a tile and marble shop ? Well you would know the materials then ;) These are called garden paving stones . And a 'Sadarahalli Grey' machine cut will be a close match to the pic shared. Stones are often named differently in different geo's. It's called sadrahalli in Bangalore region. thanks, Nitin Cornerstone Designs. Bangalore.

can anyone tell me what kind of flooring is used here ? thanks in advance

Hello Naisu, You should contact a fabricator for the same as it depends on the market cost of the material and the charges of the fabricator. But the square pipes need to be of good quality and better gauge then only it will sustain the weight of this book shelf.
