Left-handed anchor rods

Left-handed anchor rods (also known as threaded steel anchor rods) are materials used for rock support in underground projects such as mines, railways, and hydropower stations. Their main function is to ensure the stability of the surrounding rock in tunnels. 

Structural features

The left-handed anchor bar body is in a left-handed form as a whole, with left-handed threads on its surface. It is usually made from round steel bars through processes such as cutting and threading.

Application

It is mainly used for tunnel support in coal mines, railways, hydropower and other projects, achieving various support methods such as end anchoring, extended anchoring and full anchoring. Its threaded design can provide greater anchoring force in complex geological conditions (such as hard rock or fractured rock areas), reducing the risk of loosening and falling off. 

Advantages

It is easy to operate and has a low cost, and is widely used for the stability of surrounding rocks in various underground projects.
