  • 520N/mm≤ yield stress
  • a high strength, weldable, structural steel
  • available in long lengths (up to 12m) with rolled threads to BS3643
  • can be supplied self colour, painted or galvanised

High strength structural tie rod system with high specification cast forks.

Our SBS-520 carbon steel tie bar system is manufactured with characteristic yield strengths of 520 N/mm2.

Our range of carbon steel structural tie bars can be supplied from M12 to M100 sizes, commonly we supply M12, M16, M20 and M24.

The tie bars set to their nominal pin-to-pin length and are supplied pre-assembled which means they are ready to be incorporated into the structure saving valuable time on site.
