Ribbed steel bars produced by hot rolling are divided into common steel bars, high-strength steel bars, steel bars for welded structures, low-alloy steel bars, and stainless steel bars. Among the common steel bars, flat-headed steel bars, corrugated steel bars, and cold-headed steel bars are mainly used. The hot-rolled ribbed steel bar is a ribbed bar made of ordinary low-carbon steel. Its process is a hot-rolled round bar, and the middle part is pointed out to form a constant-pitch thread. The steel ribs on both sides have a double-section effect; the shear of the slits increases the bonding area with the concrete, and increases the mechanical bond between the steel bar and the concrete. It has better seismic performance.
The hot-rolled ribbed steel bar produced by our company is mainly Ordinary Level III (YB/T192-2009): 4.8mm-32mm, and its mechanical properties are different with different nominal diameters. The standard value of tensile strength fT is 300-520MPa, and its elongation rate A is ≥18%. Rebar with vanadium can be produced according to the requirements of customers. After treatment and added on, the RB/T192-2009 grade III rebar produced has a tensile strength of no less than 520MPa and an elongation rate of no less than 26%.
The Grade III hot-rolled ribbed steel bar with vanadium content produced by our company not only has high strength, but also has good comprehensive mechanical properties. In addition, the hot-rolled ribbed steel bar with added vanadium has good corrosion resistance and fatigue resistance. Especially in aggressive medium environment, the fatigue resistance and corrosion resistance of Grade III hot-rolled ribbed steel bar with vanadium content are superior to Grade III hot-rolled ribbed steel bar without vanadium content. In engineering construction, ribbed steel bars with vanadium are mainly used in the construction of high-rise buildings and bridges. The addition of vanadium to ribbed steel bars provides the engineering with higher strength, higher elastic limit, and better seismic performance, thus providing a guarantee for the safety and stability of the engineering structure.
The Grade III hot-rolled ribbed steel bar with vanadium content produced by our company has a wide range of applications. It can be used for the reinforcement of buildings, bridges and other structures, as well as for anchors, couplers and other industrial structures. It has good plasticity and toughness, so it can better resist shock and seismic load. In addition, due to its good weldability, the Grade III hot-rolled ribbed steel bar with vanadium content can be welded directly with other structural parts, which can effectively improve the structural strength of the engineering.
The grade III hot rolled ribbed steel bar with vanadium content produced by our company conforms to the international standard and has been certified by the national quality inspection department. It is an ideal material for reinforcement of buildings and bridges, and has been widely used in these fields all over the world.
