Abstract
This scientific article represents a detailed and comparative analysis of metal and concrete structures, two key options in the field of construction. The assessment focuses on several dimensions, covering key aspects such as structural strength, durability over time, environmental sustainability, and associated costs. Data for the analysis were obtained from a wide range of real structures, from skyscrapers to bridges, providing a solid foundation for the study.
Rigorous methods were applied, including static and dynamic tests, as well as life cycle analysis to obtain accurate and meaningful results. This multidisciplinary approach allowed for a comprehensive understanding of the advantages and challenges associated with each type of construction. The conclusions drawn provide valuable guidance for engineers, architects, and decision-makers in the construction industry.

Keywords: Metal structures, concrete, construction, strength, durability.
