Solid-bar nails
In contrast to hollow bar nails, solid bar nails must be installed into a supported or stable borehole. Due to the high-strength threaded bars forming the load-bearing element, they provide a high load transfer capacity with a comparatively small borehole diameter.
Structure
Solid bar nails consist of three main components:
Nail head
Steel tension member
Grout body
The steel tension member is designed as a round steel bar with hot-rolled coarse thread ribs, allowing it to be cut or coupled at any required position.
Features
Nationally and internationally approved system with internal and external quality monitoring
Excellent adaptability to transport and installation conditions due to delivery in segments with coupler connections
Easy on-site length adjustment, e.g. under varying geological conditions, by using segmented elements with coupler connections
Excellent bond between the threaded bar and cement grout due to the thread ribs
Optimal adaptation to required load capacities through a wide range of available cross-sections
Structural variants
Short-term nail, temporary, with standard corrosion protection (SCP)
Short-term nail with extended temporary corrosion protection (ASCP) – standard corrosion protection considering corrosion rates or additional coatings (e.g. galvanizing)
Permanent nail with double corrosion protection (DCP)
