Advantages and Disadvantages of Finishing Rolled Steel

Finishing rolled rebar is the 1 kind of construction steel bar. It is divided into two ways: hot rolling and cold drawing: hot rolling: after heating to a certain temperature, the round steel is rolled and formed by several rolls. Advantages: high production efficiency and low cost.

Disadvantages: high requirements for mechanical equipment and process technology.

Due to the influence of ribbed (spiral) shape, the steel bar is prone to buckling deformation when it is subjected to longitudinal force.

Cold drawing (cold drawing): The round steel is heated to a certain temperature before cold working and forming.

Advantages: simple production process;

Because the shape of the ribbed (spiral) has less influence;

High production efficiency and low cost;

Finishing rolled threaded steel bar has simple anchoring, strong adhesion, safe and reliable tension anchoring, and reliable quality. The greater the strength-to-yield ratio of the finish-rolled rebar, the greater the force of the steel, the greater the reliability at work, and the higher the safety; but the strength-to-yield ratio is too large, the strength of the steel is low, and the material is wasted. Steel can withstand the performance of eternal deformation before force failure, which is called plasticity. The greater the elongation, the greater the plasticity of the steel. Products are widely used in deep foundation pit anti-floating anchor, basement tensile anchor, bridges, highways, water conservancy facilities, high-rise buildings and other basic projects.
