Manufacturing and installation of an external emergency staircase for a hospital

For buildings where the safety of occupants is a constant priority, an external emergency staircase is an essential element of the building's safety structure.

H Metal supplied the steel profiles and tubes used to build this metal structure.

Such structures are designed to ensure access to the outside in emergency situations and must provide long-term stability.

The choice of materials plays an important role, as each component contributes to the strength of the entire assembly.

The materials used in such structures must ensure strength and reliable performance over time.

Steel is frequently used due to its good behavior under mechanical stress and its ability to adapt to different structural configurations.

In addition to its functional role, such a structure must allow for efficient integration into the building and provide safe conditions of use. Building a metal structure of this type involves using suitable materials and complying with the requirements set out in the technical project.

Materials used – external emergency staircase

Several types of steel profiles and tubes were used to build this structure, each with a clearly defined role within the overall assembly.

The materials used in the project were:

– UNP 200 mm profile made of S275JR steel;

– UNP 300 mm profile made of S275JR steel;

– 80x80x10 mm angle made of S235JR steel;

– square tube 150x150x6 mm made of S355J2H steel;

– rectangular tube 150x100x6 mm made of S355J2H steel.

These materials are chosen according to the structural requirements specific to an external emergency metal staircase.

UNP profiles are used for the main elements of the structure, where load-bearing capacity and overall rigidity are required. In the case of external emergency staircases, these profiles contribute to the stability of the entire assembly.

The angle profile is used in joining and stiffening areas, where precise fastening between components and structural reinforcement are required.

Square tube is used for the vertical support elements. It has the role of bearing loads and maintaining stability along the height.

Meanwhile, rectangular tube completes the structure in the intermediate areas, where adaptation to the geometry of the construction and correct load distribution are required.

Important aspects regarding the manufacturing and installation of the metal structure

Building a metal structure for evacuation purposes involves several successive stages, in which each element is prepared and integrated into the structure according to technical requirements.

The process begins with cutting the profiles to the dimensions specified in the project. This stage is important because precision influences how the entire structure is assembled.

Afterwards, the elements are assembled to form the main structure. Correct positioning of the elements ensures the stability of the structure and a balanced distribution of loads.

The intermediate landings serve to connect and organize the flow of movement.

The structure is integrated into the building so that the metal assembly functions as one with the existing construction.

Durability and long-term use of metal structures

Metal structures used for evacuation purposes are designed for long-term use and to withstand the environmental conditions specific to an outdoor location.

Steel is a frequently used material due to its strength and workability. This makes it possible to build structures adapted to different types of buildings.

Over time, exposure to environmental factors can affect the behavior of outdoor metal structures, especially under conditions of humidity and temperature variation. For this reason, they are usually protected through galvanizing, in order to reduce the risk of corrosion and degradation during use

A properly built structure has a long service life and requires minimal maintenance. This aspect is important for medical buildings, where continuous operation is essential.

Conclusion

Building an external emergency staircase requires the use of durable materials and a configuration adapted to the requirements of the building.

UNP profiles, angles and steel tubes are frequently used for this type of evacuation structure, due to their strength and versatility.

The resulting structure is built to ensure safe access to the outside and to meet the specific requirements of a medical facility.

H Metal supplies UNP profiles, angles and steel tubes for metal evacuation structures, available in standard or galvanized versions.
