List of Rock Anchor Bolt Manufacturers 2022

A rock bolt is a long anchor bolt, which is placed in boreholes to stabilize the rock mass. It includes bolts, cables, dowels, and nails. Rock bolts were first used in the 1940s and further developed in 1947 by Australian engineers. Now, rock bolts are crucial components that support structures such as tunneling, mining, and other underground engineering projects.
