What is cold drawn steel?
It use cold extrusion technology to pull out various types section steel.
Like round steel bar, square steel, flat steel, hexagonal steel. And other special-shaped steel with high precision and smooth surface.
The concept of cold drawn steel bars:
For the purpose of saving steel and improving the yield strength of steel bars. The method of drawing steel bars with tensile stress that exceeds the yield strength but less than the ultimate strength is called plastic cold-drawing.
