Black Pipe Cold Rolled Pre Welded Steel Tube Hollow Section
Cold Rolled Steel Tubing
This steel tubing begins as hot rolled steel but is processed even further to create a more finished surface and provide additional strength. This process is more suited for applications that have strict tolerance, straightness, and surface condition requirements because cold rolling is a more precise finishing method.

Cold Rolling Technology Introduction
Cold rolling refers to cold-drawing, cold-bending, cold-drawing and
other cold processing of steel plates or steel strips into various
types of steel at normal temperature.
It has the advantages of fast molding speed, high output, and does
not damage the coating, and can be made into a variety of
cross-section methods to meet the requirements of operating
conditions. Cold rolling can cause large plastic deformation of the
steel, thereby improving the yield point of the steel.
Cold-rolled formed steel allows partial buckling of the cross
section, which enables full application of the bearing capacity of
the member after buckling.
