w型钢带

w钢带也叫顶板钢带，是用高强合金板冷压而成，与各种锚杆共同组合组成锚杆的整体性，是软弱岩石和煤顶板控制的最佳选择。广泛应用于矿井下巷道，工作面切眼，峒室及其它领域的巷道支护，对处理不稳定围岩效果更佳。

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.

应用原理：

application of principles

通过w钢带把分散的多根锚杆联结起来形成一个整体承载结构，显著地提高锚杆支护的整体效果，在不完整的顶板岩中应用效果更好。

应用原理：

an overall bearing structure was formed by linking several dispersed bolts through the w steel strip, which could significantly improve the integral effect of the bolt supporting and get a better effect on the application with incomplete roof rock.

技术特点（同普通下钢带相比）

technical characteristics (compared with ordinary steel under)

1、原料采用高强合金带钢。

2、具有更高的刚性和强度。

3、w钢带抗弯截面模量提高54倍。

4、w钢带在冷压过程中的硬化作用可提高抗拉强度28-46%。

技术特点（同普通下钢带相比）

1、using high strength steel alloy material

2、higher strength and rigidity

3、w steel strip got 54 times higher on anti-bending section modulus.

4、w steel strip can be improved 28-46 percent on tensile strength because of the hardening effect in the process of cold process
