Product Description

Left Hand Mine Tunnel Roof Support Self Drilling Rock Grouting Anchor Bolt
Anchor rods, also known as anchor bolts, play a crucial role in various construction projects by providing stability and secure anchoring of structures.These threaded rods are designed to fasten objects or structures to concrete or masonry surfaces.zmwm15
Their ability to resist tension forces makes them essential for ensuring the structural integrity and safety of buildings, bridges, towers, and other similar constructions.
During the constructions of underground works, it is very common to encounter soft rock, fractured zone and large deformation due to high ground stress. In the case of serious collapsing, extra-long anchor is needed instead of ordinary one.
