Applications
Product Introduction
W Roof Mat also called roof steel strip,is cold-sealed by high alloy plates,and composed of integrity jointly combined with all kinds of bolts,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.
Features and Advantages
-Using high strength steel alloy material.
-Higher strength and rigidity.
-W Roof Mat got 54 times higher on anti-bending section modulus.
-W Roof Mat can be improved 24%-46% on tensile strength because of the hardening effect in the process of cold process.
