Stairs are used in lieu of elevators in buildings or houses and also play a very important role as emergency exit areas in office buildings and commercial spaces. Until today, staircases were built using marbles and granite, which are expensive, require onsite cutting and finishing, leading to a lot of wastage. They need a lot of manual labor for handling and fixing.
