Steel construction refers to a building in which the entire load-bearing system is made of steel. It is generally preferred in areas with high earthquake risk or for structures that need to span large areas longitudinally, as steel provides greater flexibility.

Facilities that accommodate large numbers of people at the same time, such as football and basketball stadiums, airplane hangars, and large warehouses, are typically built with steel. The reason steel is used in such structures is that it is more cost-effective and faster to construct compared to reinforced concrete.

The assembly of steel structures is very fast. Although they can be repeatedly dismantled and reassembled, they are long-lasting. Being 100% recyclable, steel retains its properties over time and does not harm the environment.

Steel can also be used to create residential spaces. In steel-built homes, all structural elements, including the main frame, are joined using rivets and specialized screws, increasing earthquake resistance and preventing cracks during seismic events.

For example, while a two-story reinforced concrete villa may take 3 to 6 months to complete, a two-story villa using steel construction can be finished in 45 to 60 days.

The world-famous Eiffel Tower in Paris, which is 7,300 meters long, is entirely made of steel construction. Despite experiencing numerous earthquakes, it still stands tall.

In Turkey, after 1999, steel prices were reduced through government intervention, and the construction of steel buildings is encouraged in earthquake-prone regions of the country.
