The main components of a staircase
- The steps. They are placed horizontally, they are called treads and the vertical plate, at which at one end of thread rests, is called risers.
- String. Beams set in an inclined position and which are a basis.
- The open strings. Surfaces, placed vertically and resting against a string. At one end they join the feet.
Support pieces. These include stands in spiral staircases and rails in structures fixed to the wall.

Types of ladders
The stairs are basically marching, spiral and on the rails.
These ladders for the house can be done with your hands. They can be straight, two-marching and multi-flight. Afford device in the house of the sustainer design is possible only in the presence of a large area. The number of marches and staircases depends on the height between floors.
When calculating the size of structures it is necessary to measure the height of the wall to which it is moved. Then you should create a right triangle, the legs of which are wall and floor, and hypotenuse is a flight of stairs.
The angle of inclination is best done at about 45 degrees. If there is no such angle, it is advisable to design double staircase.
Width depends on the size of the premises, the physique of the inhabitants of the house and their tastes.
According to the construction standards, a march should consist of ten steps.
If there are more of them, they should be split with staircase. Width is equal to width of stairs and length to match the average step of a person.

The arrangement depends on the dimensions of the room height between floors and aesthetic preferences of the house owner. Structurally, the main structures are divided into direct (only one) and a swivel that allow you to save useful space, for located along the wall. The stairs can be equipped with a closet or pantry.

Helical design of stairs for a country house is appropriate in the case when the house has very little space. The dimensions of such structures depend on the size of the steps. The successful operation of the spiral requires space twice the length of its steps.
Moving up the stairs of this type is not exactly comfortable, its main advantage – compactness. In addition, it can give a special charm to the interior.

Staircases on bolts
Due to the fact that these constructions have no closed and open strings, they are very graceful, appearing to float in the air. The steps are fixed to the wall with pins, which are large bolts, mounted into the wall with one hand.
Staircases on bolts are quite durable, can withstand weight up to six tons. An indispensable element in the construction of railings will ensure safe operation.

- Oak has the ability to absorb oil, leaving the wood unsightly marks.
- Pine should not be used at all, as its wood is very resinous, soft, prone to damage.
- Larch good for stairs, rot proof.
- Cherry and pear are very strong and not prone to mechanical damage can be an excellent material for stairs.
A very popular metal. Best choice is stainless steel. Such designs are very durable and reliable, not prone to deformation and corrosion, are able to decorate any room.
For manufacturing steps, you can use stone, it can be granite or quartzite, because they are particularly durable and abrasion resistant. A good option could be the artificial stone for a nice balance of quality and price. Marble is not very suitable for making steps as it is rather soft and over several years may be purged.
Stairs with glass stairs look very stylish and fashionable. Glass for the manufacture of steps should be tempered or laminated, lightweight acrylic can also fit.
