One of the primary reasons for the dominance of metal in construction is its exceptional strength-to-weight ratio. Unlike reinforced concrete, which is heavy and bulky, structural steel provides high load-bearing capacity with significantly less mass. This lightness reduces the overall load on foundations, allowing for taller structures and more efficient builds on challenging ground conditions. Furthermore, the ductility of steel—its ability to deform without fracturing—makes it the preferred material for high-seismic zones, as it can absorb and dissipate energy during earthquakes.
