R ibbed rebar is an indispensable material for reinforced concrete structures and significantly enhances the durability of buildings. The cross patterns and protrusions on its surface, known as ribs, strengthen the bond between the rebar and concrete, improving its slip resistance and ensuring the safety of structures. These bars are typically made from low-alloy steel and contain elements such as carbon, manganese, and silicon. This composition helps the rebar gain superior mechanical properties, such as high tensile strength and flexibility. Ribbed rebar is produced in various strength classes, such as S420 or S500, allowing it to be selected based on the needs of the structure. With an elastic modulus of approximately 200 GPa, these bars maintain their strength without deformation under load.

The applications of ribbed rebar are extensive, and it is commonly used in the beams, columns, and slabs of reinforced concrete structures. It is also frequently chosen for large-scale engineering projects such as bridges, dams, tunnels, industrial plants, and the production of prefabricated structures. This versatility allows ribbed rebar to make structures more resistant to both static and dynamic loads. In standard production, the diameters of these bars typically range from 8 mm to 40 mm, with a standard length of 12 meters. However, production in different lengths and diameters is also possible depending on the project's requirements. For example, a 12 mm diameter rebar weighs approximately 0.888 kg per square meter, which is an important parameter in structural design.

One of the greatest advantages of ribbed rebar is its high bonding capacity with concrete. This property significantly reduces the risk of slippage in reinforced concrete systems and contributes to making structures more resistant to dynamic loads such as earthquakes. Additionally, the ease of cutting and bending on construction sites offers flexibility in application and saves time in terms of labor. To prevent rust, various coating and galvanizing methods can be used to protect the rebar, thus extending the lifespan of the structures.

The production of ribbed rebar in Turkey is typically carried out in accordance with the TS 708 standard. Internationally, the EN 10080 standard is used as a reference. All these features make ribbed rebar a crucial element in modern construction projects and one of the foundational components of durable, safe structures.
