Rock Safety

Pipe Bolts

Pipe Bolts

Pipe bolts are initially anchored with expansion shells, and later cast in rapid hardening cement
. Secured with an expansion shell, the bolt provides immediate work safety. Pipe bolts are not permanently safe until cast in concrete.

The bolts are delivered with threads sized 150 mm on both ends. The pipe bolt can be used for most rock types, especially slate and layered rock to create the dowell effect. A fully cast bolt provides this effect.

Dowell effect = the bolt absorbs shear stress as well as tension force.

Available with GalvaCoat for corrosive conditions
