Side staircases are modern style staircases. The supporting elements of these staircases are struts (sidewalls) made of steel or stainless steel, on which scales and possibly risers are attached. The staircase can be made higher on the wall for ease of staircase cleaning.
These staircases can be produced both closed with risers and open without risers.
The railing is usually made of glass, metal or stainless steel.
