Compared to other types of stairs, the helical design has a number of advantages that distinguish them favorably from marching stairs. First of all, it should be noted that a screw-type staircase product is a rather effective and original element of interior design..
For the construction of such structures, significantly less funds are required than for other types of stairs. Spiral staircases do not require significant space for their placement, since metalie spiral staircases are placed in a canopy, around a post or base. It is not very difficult to create such elements. The main thing is to take into account that spiral-type staircases are effective if they are installed in rooms where there is no large flow of people and there is not a large amount of free space..
In addition, one of the main features of this type of structures is that the small width of the steps can be a source of increased injury, and therefore it is necessary to move along such structures slowly, carefully and with increased caution. This task can be facilitated by installing durable and comfortable handrails on a spiral staircase, correctly calculating the size of the steps and the size of the tread.
Experts note that it is quite possible for almost everyone to independently make this type of interior design element, taking into account the observance of the main points regarding the features of spiral staircases. So, to ensure convenient movement along the specified structure, it is recommended to make spans with a width of at least 1 meter. In this case, the diameter of the entire staircase will be within two meters.
Most often, screw-type stairs are made in the form of a structure, which includes steps, which are fastened to the central post and handrails with balusters on them. In other cases, when structurally spiral staircases are made without the use of handrails, to which the steps are actually fastened, it is necessary to make significant amounts of labor and money.
The geometry of a stair screw located in a horizontal plane can be polygonal, in the case of a spiral staircase near the walls, or round..
