About Cold drawn steel bar:

Cold drawn steel bar is made from hot rolled steel bars or wire rod. Depend on the ship of the mould, cold drawn steel bar can can
be classified as cold drawn steel round bar, cold drawn steel square bar, cold drawn hexagonal steel bar, cold drawn flat bar and
other shapes of cold drawn steel bar or profiles.

Our advantage of cold drawn steel bars:

1.Precision size tolerance(h8, h9,h10, h11)
2.Good roundness
3.Good straightenss(0.2mm/m, 0.5mm/m, 1mm/m, 2mm/m)
4.Suitable sued mechanical properties (We can do heat treated according to final usage)
5.Good roughness to bright surface ( 0.4um, 0.6um, 0.8um)
6.More processing (Straightening, polishing, grinding)
7.Machinability is improved leading to a better tool life
8.No brittle, UT testing
9.Professional technical service
10.Competitive price
11.Fast delivery
