Cold drawn square steel refers to cold drawn steel with a forged square shape. Cold drawn steel is the use of cold extrusion technology to pull various high-precision, smooth surface round steel, square steel, flat steel, hexagonal steel, and other special-shaped steel through precise molds. Widely used as a substitute for threaded steel in steel grating, steel structures, or reinforced concrete. Specification: 3 × 3mm -80 × 80mm

Cold drawn steel is a type of steel that, under normal temperature conditions, is subjected to a tensile stress that exceeds the original yield point strength of the steel bar, forcing the steel bar to undergo plastic deformation in order to improve the yield point strength of the steel bar and save steel.

The concept of cold drawing of steel bars: With the aim of saving steel and improving the yield strength of steel bars, the method of stretching steel bars with tensile stress exceeding the yield strength but less than the ultimate strength to produce plastic deformation is called cold drawing of steel bars.
