Structural steel is a highly studied and widely used building material in construction, known for its predictable behavior. Primarily
made of carbon steel, it contains iron and up to 2.1% carbon, with higher carbon content increasing yield strength and reducing
ductility. Its main function is to reinforce structures, forming the skeletal framework that supports buildings. Additionally, it is 100%
recyclable and classified into types.
