Rebar
High Quality Factory Price HRB400 HRB500 Best Selling Reinforced Steel Bar 8mm 10mm 12mm 16mm Diameter for Building Material
Different physical and mechanical properties. Due to the different chemical composition and strength of steel bars, the physical and mechanical properties are different. Round steel has better cold bending performance and can be made into 180-degree hooks, while rebar can only be made into 90-degree straight hooks; round steel has better weldability and can be made with ordinary carbon welding rods, while rebar must be made with low alloy welding rods;
What is the role of the ribs on the surface of rebar?
Ribbed steel bars mainly bear tensile stress in concrete. The transverse ribs on the steel bars are used to enhance the bonding performance between the steel bars and concrete and better transfer stress. Simply put, it allows the steel bars and concrete to work better and bear external forces together. Due to the effect of the ribs, the rebars and concrete are bitten together, and have a greater bonding ability with the concrete, so they can better withstand the external force and improve the strength of the concrete. Then the compressive strength and bending resistance of the building will be better, and it can also effectively resist disasters such as earthquakes. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.
Production process of rebar
Rebar is produced by small rolling mills. The main types of small rolling mills are: continuous, semi-continuous and horizontal. Most of the newly built and used small rolling mills in the world are fully continuous. Popular rebar rolling mills include general high-speed rolling rebar rolling mills and 4-cut high-yield rebar rolling mills.
