Soil Nails/Thread Bar 500


Manufactured from hot-rolled, continuously threaded high tensile bar, manufactured in accordance with ISO 9001 :2000. These products are used in lateral support applications in the civil and construction industries.

  • No reduction in load capabilities as threads exceed the nominal bar diameter
  • Robust thread design accepts harsh handling without affecting threadability
  • Increased bond strength achieved owing to large surface area of ribs
  • Continuous thread enables retensioning in the event of “scaling”, as well as cutting of the bar at any point
  • Thread profile offers excellent mixing capabilities in resin installations
  • Thread profile is ideally suited to hot-dipped galvanising whilst maintaining threadability of the system
