Steel constructions are an important part of modern architecture and construction technology. These structures have a wide range of applications due to the durability and flexibility of the steel material. Steel constructions are created by producing the main structural elements such as columns, beams and frames, which are the basic components of the structure, from steel. These structural elements are then brought together to form a complete steel structure. Steel constructions are ideal for structures that require large spans, especially large industrial buildings, sports facilities, bridges, stadiums and airports. Steel constructions offer many advantages. Steel is lighter and more durable than other building materials, which speeds up the construction process and reduces costs. Steel is resistant to various adverse conditions such as fire, earthquake, storm and other natural disasters. Steel is also recyclable and environmentally friendly. Steel constructions are ideal for open-plan designs, which are one of the most important features of modern architecture. Steel structural elements make it possible to achieve wider spans by using fewer columns and beams. This gives architects greater creative freedom and allows them to achieve aesthetically pleasing designs.
