Deformed Steel Bar

Deformed steel bar, also known as rebar, is a type of reinforcing steel featuring longitudinal and transverse ribs on its surface. These ribs—typically crescent-shaped, spiral, or herringbone—significantly enhance the bonding strength between the steel and concrete, allowing them to form an integrated structure that jointly resists external forces. As the "skeleton" of concrete structures, rebar plays a critical role in improving tensile and shear strength. Depending on material composition—such as ordinary hot-rolled rebar or thermomechanically treated rebar—and available in various grades and specifications, it meets a wide range of strength requirements for construction projects. Rebar is widely used in buildings, bridges, tunnels, water conservancy facilities, and other structural applications. Compared to plain round steel, the mechanical interlocking provided by the ribbed surface greatly enhances structural integrity and load-bearing capacity, making deformed rebar an indispensable material in modern civil engineering.
