As mentional before, the cold drawing of u-shaped steel is completed under normal temperature conditions, by stretching the steel bar with tensile stress exceeding the strength of the original steel yield point, the steel bar is plastically deformed, thereby increasing the yield point strength and saving of the steel bar. The ambient temperature mentional here is basically five degress higher than the average outdoor temperature to achieve the ideal cold drawing effect.

However, the cold drawing is different, when processing, the u-shaped steel is simultaneously subjected to tension and extrusion, and plastic deformation occurs. Cold-drawn products have also changed a lot from the previous ones, such as reduced cross-sectional area, cold work strengthening, tensile strength improvement, etc., to meet different production needs.

It can be seen that the cold drawing and cold drawing of u-shaped steel are two different concepts, they are two different processing methods and must be treated correctly.
