An EeStairs open staircase gives a sense of space and of freedom. There are no risers, so you can look through the staircase, to what is beyond. An open structure is the result. The treads are fixed between two stringers. EeStairs always supplies open staircases with balustrade attached to either both or one of the stringers.
You have a choice of different materials for the treads including timber, stone, glass or steel. The latter is the cheapest, but you can also choose a combination of materials to create a more exclusive look. Such a combination is suitable for any style: a straight flight of stairs, a helical staircase, and also spiral staircases or quarter turn staircases. It's entirely up to you.
