  • Cold Drawn Steel Tube
    Tenjan Steel Tube provides a variety of Cold Drawn Seamless tubing, Shaped Tubes, Cold Drawn Welded Pipes and Cold Drawn Steel Bars. Cold Drawn Steel Tube offers uniform tolerances, enhanced machinability, and increased strength and tolerances compared to hot-rolled products. Cold Drawing process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless.
  • Free Cutting Steel Tube
    Tenjan has succeeded in producing seamless tube from free-cutting steel. Its high sulphur concentration offers advantages in machining operations such as turning, milling or drilling, with better chip formation and longer tool life. Free cutting steel tubes are guaranteed lead-free to protect the environment.

  • Bolted Rebar Coupler
    TenJan Mechanically bolted Coupler provides a cost effective method of jointing reinforcing bars, particularly when the fixed bar is already in place and there is insufficient place for a hydraulic swagging press. They are easy to install and suitable for yield strength of grade 500 reinforcing bar. Neither bar end preparation to form the thread, nor bar rotation are required.t Mechanically bolted couplers can also be used to join imperial, plain round or deformed reinforcing bars.
