In the construction field, steel bars are the main skeleton material of concrete structures and are used to enhance the tensile capacity of concrete. It is mainly used in the construction of beams, columns, slabs and other components, and improves the overall bearing capacity and seismic performance of the structure through the close combination of steel bars and concrete. In addition, steel bars are also widely used in prestressed concrete components, and the prestressing technology makes the steel bars subject to tensile force by applying a certain tension before concrete pouring, and drives the concrete to carry a part of the working load, thereby improving the bearing capacity and seismic performance of the structure. Steel bars can also be used for foundation reinforcement, by burying a certain amount of steel bars in the soil, effectively increasing the bearing capacity and seismic performance of the foundation. In addition to the application in structural engineering, steel bars can also be used for architectural decoration, such as using steel bars to make sculptures of various shapes, garden landscapes, railings, etc., to increase the aesthetics and artistic sense of buildings.
