W Steel Strip Product Introduction

W steel strip is a new type of mine support and tunnel support material. This product can organize and combine bolt support together with various bolts. Through it, multiple scattered bolts can be connected to form an overall bearing structure, which can significantly improve the overall effect of the bolt. In incomplete roof strata, it is better to deal with unstable surrounding rock.

W steel strip is named because its cross section is very similar to the letter "W". The material of W steel strip is Q235.

W steel strip, also known as roof steel strip, is a section steel product formed by continuous cold bending and rolling with longitudinal shear strip as raw material.

W-steel strip is a new type of mine support and tunnel support material. Its function is to form bolt support grid together with bolt, which plays a supporting role in rock wall or roadway. W steel strip is widely used in the roadway support of underground mine, working face cut, chamber and other fields, which has better effect on the treatment of unstable surrounding rock.

W Steel Strip Product Features

1. The model can be selected according to different geological conditions and working environment;

2. The modulus of bending section is increased by 37 times, and the modulus of downward section is about 2.75 times of that of upward section. Therefore, when installing, the anchor drill is used to tighten upward;

3. Compared with other types of steel strip, W steel strip is more difficult to tear, and its steel degree is larger, about 70 times higher;

4. The hardening effect during cold rolling can increase the tensile strength by 12% - 15%;

5. High section utilization, material saving and low price.

Four characteristics of W steel strip

1. The raw material is high-strength alloy steel strip, which is transformed into W-shaped steel strip by cold pressing, cut off according to the length requirements, and then drill;

2. Higher steel and strength;

3. The modulus of bending section of W steel strip increased 54 times;

4. The hardening effect of W steel strip during cold pressing can increase the tensile strength by 28-46%.

W steel strip performance specification

Common width: 180mm, 200mm, 220mm, 250mm, 280mm, 300mm

Common thickness: 2.5mm, 2.75mm, 3.0mm common aperture: 40mm * 60MM 30mm * 70mm

The length of W steel strip can be customized according to the actual needs of customers.

W steel band combines multiple bolts to form a whole bearing structure, which can significantly improve the overall effect of bolt support, and the application effect is better in incomplete roof rock. It has the advantages of reducing support cost and saving support steel.
