Steel is characterized by high strength, light weight, good overall stiffness, and strong resistance to deformation, making it especially suitable for the construction of large-span, ultra-high, and super-heavy buildings. The material possesses excellent homogeneity and isotropy, behaving as an ideal elastic body that aligns with basic engineering mechanics assumptions.

Furthermore, steel offers superior plasticity and toughness, allowing it to withstand large deformations and dynamic loads effectively. Its high degree of industrialization facilitates a short construction period and efficient project execution.
