A: Terrazzo stair slabs are generally more durable in terms of abrasion resistance. While concrete can crack more easily under heavy use, terrazzo's composite nature with aggregates makes it more resistant to wear and tear.

A: Yes, they can be cut using diamond - tipped saws to fit the specific dimensions of custom - designed staircases, including irregular shapes.

A: Yes, they are often used in commercial buildings such as office buildings, hotels, and shopping malls to create an upscale and durable staircase.
