B500B steel is classified as reinforcing steel and is one of the most popular steel grades used for concrete reinforcement. The letter B stands for steel intended for use in construction, the value 500 is the yield strength given in MPa. Its high strength parameters and good weldability make it widely used in the construction industry, ensuring the durability and safety of structures.
Thanks to its manganese and silicon content, B500B steel exhibits high mechanical properties that make it an excellent material for reinforcing concrete structures. B500B steel has a high yield strength and high tensile strength, making it an ideal material for structural applications. It is characterized by good weldability and ductility.
B500B steel can withstand heavy loads and is resistant to deformation. It can be used in structures operating under both constant and repeatedly varying loads, static and dynamic, in the temperature load range from -60 to +1000C. B500B ribbed bars should be welded by welding or electric welding.
