I must say that the form of a spiral staircase can be not only the traditional round shape, as usually presented – it could be another difficult design, polygonal. For the manufacture of spiral staircases, as a rule, use a tree. Their use allows you to create original designs and unique interiors. Interesting options that spiral staircases are located in the center of the room and not arranged in a bearing wall. Despite the fact that the helical staircase space saving, straight stairs used much more frequently. This is because the spiral staircases are less convenient than direct. Descend on them must be very carefully and cautiously. Therefore, marching designs are more popular.
A screw options are part of the auxiliary structures (in basement), the same grand staircase in the house usually has a march construction. In addition, a spiral staircase is sometimes the only option in cases when there is too small an opening for a marching unit design. There are spiral staircases and a sufficiently large diameter (up to three meters). Though experts agree that such openings are much more profitable arrange a ladder-type sustainer. Marching cycle may even get a job in the doorway, having dimensions of two meters by two meters. Depends on the size of the opening slope stairs, it is higher, the smaller aperture.
Although, it should be noted, flat ladder does not mean unique amenities. Comfortableness is made up of several components. Stairs are usually manufactured in a particular house with the specific terms and that its optimal size is convenient for its operation. Most appropriate height of the step recovery, which is 15 -19 cm, while the handrail shall have a height of 90-95 cm Stairs Bolza Stairs Bolza are an alternative design solution as opposed to traditional ladders or screw-type sustainer. German word translated as bolz bolt or pin, it looks as fasteners, suspensory Staircase design in the living room. Stairs and railing secured by Boltzmann to the wall, they may be located on rod bearings made of steel. Such a constructive solution is used when there is a need to make a ladder compact. Stylistics ladder structures for Bolza modern enough, can be used in the avant-garde interiors. While good looks and traditional interiors. Mounting the steps in the stairways, in Unlike designs, made with bolts directly to the wall, along which necessarily passes ladder. Stairs to the Bolza in the current time are quite popular. They are fragile and easy to look – a visual illusion. 'Boltzmann' strong enough for use. Manufacturers of such ladders believe that not very much at home stairs Bolza able to withstand the weight of a hundred guests at a time, and only one step can keep the weight to 1800 kg. Such characteristics stairs due to the fact that the bolts are fastened with strips of rubber. Among other things, staircase to Bolza quite comfortable and safe to use. Thanks to the rubber pads, vibration during operation of the stairs is minimal, which reduces the load that is carried on the joints and spine. Wooden stairs to the Bolza differ from all others in that it does not squeak, because they do not allow friction tree on a tree. It must be said about the aesthetics of these structures, an important advantage of such stair. Aesthetics ensures the absence of heavy string and Kosourov, stair railings and a variety of designs. Such a staircase in a small space does not diminish the size of the room, not eating up the volume and light.
