Solid-bar nails

Solid-bar nails consist of three main components: the nail head, the steel tendon and the grout body. The steel tendon is a round steel bar with coarse, hot rolled thread ribs and can therefore be cut or joined at any desired point.

 

Features:

  • National approval pending
  • Well suited to transport and assembly conditions thanks to delivery in parts with couplers
  • Good screwability thanks to rugged coarse thread
  • Simple to adapt to required length on site, e.g. with varying geological conditions (can be shortened by cutting or lengthened with a coupler)
  • Excellent bond between threaded rod and cement mortar
  • Can be closely matched to the required loads thanks to wide range of cross-sections

Types available:

Temporary nails

  • Soil nails for temporary use (service life up to 2 years)
  • Soil nails for semi-permanent use, allowing for a soil-dependend corrosion rate (service life 2-50 years)

Permanent nails

  • Permanent nails with standard corrosion protection (service life up to 100 years)
  • Permanent nails with long-term corrosion protection to EN1537 (service life up to 100 years)
