Staircase with a turn
The main feature of turn staircases is clear from their name – their design has a turn. This type of staircases is very common due to its high functionality, ergonomics and the possibility to specify any style of a staircase leading, for example, to the second floor of a private house, a dacha or a country cottage.
Designing such staircases requires certain skills and knowledge of material properties. It's great, if you know what the riser height, the total height, the stair flight and tread width and the total length of a structure are, as well as you are well-versed in modern materials and fixing methods. But it's easier to order a design of the turn staircase rather than to study the issue at length. Then what you need to do is just to decide on the tasks to be assigned to the future staircase, while designers will offer you the best options.
Depending on the space allocated for the staircase, turn staircases can have 90° and 180° turns. The former are called L-shaped; the latter, U-shaped. Staircases with 180° turns are considered more reliable and having extra strength. But everything depends, of course, on the bearing structure and its fastening methods, dividing into several basic types: on bolts, on strings, on notchboards or on newel posts. Newel posts are used, mainly for the construction of spiral staircases. The latter are also a type of turn staircases and are often used in a small space.
It is important to note that modern construction and design technologies make it possible to implement complex turns in staircases by combining two or more types of bearing structures and fasteners. Therefore, today there are practically no restrictions in the courage of designer ideas. We will help to embody them.
