W Steel Strip
- -Using high strength steel alloy material.
- -Higher strength and rigidity.
- -W steel strip got 54 times higher on anti-bending section modulus.
- -W steel strip can be improved 24-46 percent on Tensile strength because of the hardening effect in the process of cold process.
W steel strip introduction
W steel strip,also called roof steel strip,is cold-sealed by high alloy plates,and composed of integrity jointly combined with all kinds of bolt anchor,is the best choice of weak rocks and coal roof control.It is widely used in coal mine roadway,cut and other fields of roadway rock surrounding.It got better efficacy on unstable surrounding rocks.
Application of principles
An overall bearing structure was formed by linking several dispersed bolts through the Wsteel strip,which could significantly improve the integral effect of the bolt supporting and get a better effect on the application with incomplete roof rock.
