What Are The Characteristics And Usage Methods Of W-shaped Steel Strips?

1. W steel strip is a series of products, and different models can be selected according to different geological conditions and requirements.
2. The difference in section modulus between the upward and downward sections of the W steel strip is significant (the downward section modulus is about 2.75 times that of the upward section modulus). Therefore, during installation, an anchor rod drilling machine is used to tighten the steel strip upwards. The section modulus of the steel strip is very small and easy to adhere to the surrounding rock of the roof. However, when the roof is compressed, the bending section modulus of the steel strip downwards is large, causing the anchor rod to loosen and form a whole surrounding rock.
3. Compared to other types of steel strips, W steel strips are less prone to tearing and have a higher degree of rigidity.
4. The utilization rate of W steel strip cross-section is high.
Several commonly used combination support methods for W-shaped steel strips
1. High performance anchor rods, steel strips, and metal mesh
2. High performance anchor rods, steel strips, anchor cables, and metal mesh
3. High performance anchor rods, steel strips, pre tensioned trusses, and metal mesh
4. High performance anchor rods, pre tensioned anchor cables, pre tensioned trusses, and metal mesh
5. Combination of anchor rods and metal brackets
Installation and usage method of W-shaped steel strip
1. The installation and use of W-shaped steel strips are extremely simple. After drilling the surrounding rock, anchor rods are installed, and the steel strips are combined with the anchor rods in advance according to the design requirements.
2. Use an anchor rod drilling rig to install the anchor rod. After the installation of the anchor rod is completed, connect the tray with the anchor rod nut
3. Back tightly, and so on, to complete the installation.
Transportation and packaging
1. The W-shaped steel strip can be processed and customized according to the length and hole spacing required by the user.
2. The W-shaped steel strip has no packaging on the surface, but for convenient transportation, it is packaged in bundles.
