Round steel bar is ground to remove rust with machine and make a clean surface.
Bright steel bar is clean and bright with the process of grinding, used in food, pulp and paper industry.
Many pieces of bright steel bars are stored regularly in the warehouse.
Bright steel bars can be stored in normal environment with the feature of corrosion resistance. They are good material of turbine blades.


  • Surface integrity. The production process of grinding and polishing greatly improves the surface texture of bright steel bar. It's much more straight.
  • Precise dimension. It's produced by the process of straightening, grinding and fault detecting. Each bright steel bar is tested stringently by our quality control system.
  • High strength. The process of annealed improves the tensile strength and yield strength of bright bars. Because the temperature increases slowly, it leaves enough time to make the structure stronger.
  • Corrosion resistance. The bright bars are coated with oil to resist corrosion and rust during transport and storage.

Since bright steel bars are improved mechanical properties in the process of cold drawn and hardening, they have been used for a number of different applications, including: shafts, valves, fittings, gears, fasteners, food processing equipment, instruments, screws, bearings, mining machinery, aircraft parts, exhaust manifolds, pumps and so on.
