one Cantilever steps
Compact stairs of this type do not have any “extra” details — only steps, moreover, attached to the support (wall, pillar, column) with only one end, while the second one seems to rest on air. Such structures are difficult to manufacture, and in some cases, the implementation of the staircase project should begin at the stage of laying the walls: steps made of durable material, such as reinforced concrete, are partially embedded in the masonry, reinforced with reinforcing mesh or rods. Other options are anchoring steel brackets or fabricating a welded frame; these methods are even more time-consuming, but they are realizable in an already built house.
2 Steel stringers
The traditional material for stringers (bearing beams of stairs) is a wide board made of glued wood. If you replace wood with metal, you can change the shape of this part (make it in the form of a broken line) and significantly reduce the cross-sectional area. As a result, the staircase will turn out to be much more elegant without sacrificing strength.

3 Central kosour
Today it is an extremely popular type of stair beam. Such a kosour consists of Z‑shaped parts and can be either welded or prefabricated. With prefabricated stairs of this type, you can arbitrarily change the direction of the march and adjust its height by attaching additional modules. The central kosour needs to be supported by a pillar and / or additionally strengthen the structure, for example, with tie bolts.
four Boltsy
This is the name of the fasteners that connect the steps with each other into a single power structure. They allow you to stiffen the stairs on the consoles, pillar and central support beam. The bolt consists of a bolt, a spacer and a nut. Often, in the form of bolts, the lower part of the fence posts is made.
5 glass steps
They are made of laminated tempered glass with a total thickness of at least 16 mm. Glass steps are extremely spectacular, but they lack anti-slip properties and are extremely expensive (almost an order of magnitude more expensive than wooden ones). You can order such structures only from companies with many years of experience in their production and assembly.

6 Spiral and screw marches
Twisted stairs take up much less space than traditional straight ones, but in order to make it convenient to move along them, the height of the riser should not exceed 17 cm, and the width of the tread in its widest part should be at least 24 cm.
7 Transparent fence
It is made from flat or curved (radius) sheets of laminated glass. These screens, if properly installed, are extremely safe and are perfect for homes with small children. In addition, they are able to perform the function of bolts and stiffen the march. The disadvantages of glass screens are the high price and the need for regular maintenance.

eight string fencing
Railings made of steel posts and strings are no less elegant than glass, and are much cheaper. To comply with safety standards, the lower horizontal cable must be located no more than 150 mm from the level of the step; the optimal distance between the posts is also 150 mm.

9 Openwork forged railings
Such a fence, although it has a significant mass, looks almost weightless and at the same time is able to give visual lightness even to a monolithic concrete march. Patinated metal goes well with wood and natural stone, as well as stained glass.
