Roof Mat

The roof mat is a new kind of mine support material. It is made of steel sheet with a thickness of 3-5 mm and a width of 180-320 mm. After cold bending into a W-shape, a steel strip with the same bolt hole as the anchor rod is processed in the middle of the roof mat.

Technical advantages of W-shaped steel strip:

1. The bending section modulus of the W-shaped steel strip is increased by 37 times.

2. The stiffness increased by 70 times.

3. The hardening effect of the W-shaped steel strip during cold rolling increases the tensile strength by 12% - 15%.
