A steel staircase construction for insertion or placement

A steel staircase construction is in most cases designed so that the staircase can be inserted or saddled up. Different profile shapes meet the necessary stability criteria for the individual parts such as load-bearing spars, cheeks, railings and carrying or saddle points. Prefabrication ranges from prefabricated components to on-site assembly.

Prefabricated stairs are common

Steel staircase constructions are particularly common in stairwells of single-family homes. A typical representative is the staircase in a terraced house, which provides the ideal staircase under a small footprint.

The steel staircases in the interior are usually open prefabricated staircases, which are attached to the ceiling edges of the projectiles or stored "inserted". Depending on the structural conditions, the steel staircase construction can already be completely prefabricated with sub-stages or assembled and welded using modular technology.

Constructions inside and outside

Steel staircase constructions are widely used due to their small footprint while maintaining enormous stability and resilience. In addition to staircases in private houses, the main areas of use are maisonette-style apartments and escape and fire escape stairs of all kinds. An escape stairwell is not only planned and installed in buildings. In particular, metal stairs are attached to the outside of the building, for example as a refuge tower.

The flexibility in steel processing also produces many staircase shapes that guarantee space-saving, adequate and fast escape routes. As space-saving stairs, especially spiral staircases are known. The construction of a spiral staircase belongs to this type of staircase types.

Used steel profile shapes

There are six types of profiles used in steel staircase construction with specific properties:

  • HE profiles with square cross sections and wide flanges for the production of bars
  • Hollow tubes with rectangular or round cross-section for railings and light load bearing parts
  • U-shaped profiles for cheeks and support of the railing, as very resilient, but only in one direction
  • Round hollow tubes for welded joints with many accesses
  • Solid solid profiles as decorative elements
  • Angle and T-profiles used as complementary connection aids for other profiles

A steel staircase construction is always made up of a combination of several profile shapes that optimally absorb and distribute all loads and loads.

Welding and regulations

The prerequisite for the safety and durability of a steel staircase construction is a stress-free and torsion-free installation. Since there are always enormous heat effects in welded joints, the subsequent heating of other stair parts can be necessary to compensate. For this reason, the self-build a steel staircase limits and only experienced with welding people can create reliable stairs.

In addition, there are many physical conditions that must be taken into account. Thus, when measuring the prescribed stair lead in a residential house to be considered.

Tips & Tricks

The regulations for staircase construction are listed in the standard DIN 18065 and lead to a legally binding staircase formula that must be sufficiently familiar to you for steel staircases.
