How to choose the most suitable type of steel


Structural steel in contemporary architecture should not be considered a necessary evil. It integrates favorably with the architectural project, is the protagonist and provides unique aesthetics. It is a versatile, rational, sustainable and infrastructure ally material.

In the national and international market there is a wide variety of commercial structural steels for the design and construction of conventional, industrial and special buildings or of unusual characteristics.

The fact that steel takes so many years of being a basic element among those frequently used in the construction of urban buildings and industrial buildings does not mean that it has remained static. On the contrary, it has evolved continuously in many aspects: improvements and variations in the mechanical and chemical composition have been achieved.

Steel from steel fabrication service in Thomastown is a material that has inherent mechanical properties of strength, toughness, ductility and energy absorption capacity that make it the most useful of the materials used today in the construction of medium-height and tall buildings. It is used mainly in structures located in areas High seismicity, industrial and commercial buildings and special structures such as those mentioned above.

Types of structural steels

At present, it is common to find steel in the form of rolled profiles, reinforced members or composite steel-concrete sections in the construction of tall urban buildings, industrial and commercial buildings, and special structures. The best substitute for structural steels in the immediate future will be the best quality structural laminated profiles.

How to choose the most appropriate type of structural steel

  • The choice of type of steel is based on the specific needs of the structure of a building and its location. For example, if the structure will be located in seismic zones, the main mechanical properties of the material must be high strength, stiffness, ductility, energy absorption capacity (toughness) and weldability.
  • Strength is the capacity of steel that allows it to withstand the actions to which the structure will be subjected during its useful life.
  • Rigidity is the property of a steel structure that allows it to limit lateral displacements (distortions) caused mainly by lateral actions (especially wind or earthquake).
  • Ductility is the most important property of a structural steel; allows to exhibit large inelastic deformations before failure. The elongation of the steel specimen during the stress test and the area under the stress-strain curve of structural steels are representative indicators of ductility.
