Features & Applications

Features

  • Combines the advantages of a post-installed mechanical anchor, i.e. flexibility and immediate loading, with the performance of a cast-in-place headed stud
  • Close spacing and small edge distance thanks to low expansion forces
  • Self-undercutting facilitates fast and reliable installation without the need for a separate undercutting tool or additional operations
  • The resulting keying effect provides a secure hold even in cracked concrete under dynamic loading
  • Manufactured under an NQA-1 nuclear quality assurance program with comprehensive approvals

Applications

  • Safety-relevant, heavy-duty fastenings for all dynamic loading (shock, seismic and fatigue) in cracked or uncracked concrete, including applications in nuclear power plants
  • Fastenings to support heavy pipes, safety barriers, industrial machines, crane rails, dorm structures, crash barriers, roof fixings, elevator tracks, bridge retrofitting etc.
