Galvanized shield anchor bolts are a special type of anchor bolts, mainly used for connecting and fixing pipe segments in shield tunnel construction. This type of anchor bolt usually uses steel grades with good plasticity such as Q235 steel and Q345 steel, and it is not suitable to use high-strength steel. Galvanized shield anchor bolts can effectively fix the pipe segments through their special structure and materials to ensure the stability and safety of the tunnel. The special feature of galvanized shield anchor bolts is that their surface is galvanized, which not only improves the corrosion resistance of the anchor bolts, but also prolongs their service life.
