Technical and structural characteristics

In architecture, the staircase is one of the most important elements of the construction process; requiring extensive knowledge of regulatory, planning, development, construction, materials and assembly. Thus, from the beginning of the implementation, extremely close cooperation between the production company and the client are essential to the success of the project.

Since stairs connect the various floors of a building, we provide an architect for accurate design and implementation. An important design requirement ensures consistency and continuity with the architectural building style. The steel is particularly suitable as a building material carrier because of its strength and resistance to deformation. This material can be used eloquently and serves to be aesthetically pleasing. In addition, our external staircases and non-flammable fire escape stairs are an important entity of our business. The structures are extremely functional, anti-corrosive and ensure safety in the presence of rain or ice.

Relevant factors of a staircase are:

  • Purpose
  • Task
  • Available Space

A main stairway should be sufficiently large and easily negotiated for safety purposes. Smaller or narrower structures can be used in areas leading to places such as an attic or a closet. In addition, stairways must be built in accordance with the law and DIN 18065. For accurate design and calculations, one must be first and foremost familiar with the terminology and the dimensions determined by DIN 24530.


Height/Length relationship

Corresponds - DIN 24530

The safety and feasibility of a stairway is dependent on: Tread depth, Riser height and Slope.

Stairs with too short of a tread depth are tiring and dangerous, while stairs with too long of a tread depth often lead to stumble. In the latter case, the number of landings should be increased. The ratio s/a (riser height/tread depth)is called the slope ratio which is in relation to the stride of an adult: when one ascends a stair, the step length is reduced in respect to the average value of 65 cm, double the height difference that you wish to overcome.

The following rules apply to stairs:
Rule of passage: 2 steps + 1 tread depth = 59-65 cm


Stairway noise

Physical Noise requirements DIN 4109

Walking on a stair produces noise which is distributed throughout the interior of the building. We make sure we address this in our construction practices by refraining from placement of metallic elements directly on walls or concrete. Placement of adequate noise absorption materials (rubber or cork) between metallic elements and walls or concrete make our construction superior.
