Hot-rolled steel bars are finished steel bars that have been hot-rolled and naturally cooled. They are made of low-carbon steel and ordinary alloy steel at high temperature. They are mainly used for reinforcement of reinforced concrete and prestressed concrete structures. One of the most widely used steel varieties.
Hot-rolled steel bars are steel bars with a diameter of 6.5-9 mm, and most of them are rolled into wire rods; those with a diameter of 10-40 mm are generally straight bars with a length of 6-12 meters. Hot-rolled steel bars should have a certain strength, namely yield point and tensile strength, which are the main basis for structural design. It is divided into two types: hot-rolled round steel bar and hot-rolled ribbed steel bar. The hot-rolled steel bar is soft and rigid, and it will have a necking phenomenon when it breaks, and the elongation rate is large.
