Pc-Bolt R27/12 G4

Pc-Bolt R27/12 G4 is a new combination bolt for the Swedish market. It will replace the existing 25 mm rebar.

The Pc-Bolt is mounted in the rock with an expansion sleeve as a temporary anchor. After this, the bolt is cast in place to achieve a permanent anchor. The fact that the installation procedure takes place in two stages is the key to more efficient tunnel construction.

The bolt is naturally supplied with Pc-Coat™ – a duplex system for corrosion protection.
