W Shapd Steel Mining Steel Strip

1. W steel belt is a new type of mine support and tunnel support    material, the product can be combined with a variety of bolts to organize the combined bolt support, through which the scattered multiple bolts can be connected to form a whole bearing structure, significantly improving the overall effect of the bolt, in the incomplete roof rock formation, the treatment of unstable surrounding rock effect is good.
2. The W steel strip is named because its cross section resembles the letter "W", and the w steel strip is made of Q235.
3. W steel strip, also known as roof steel strip, is a section steel product formed by continuous cold bending rolls of multiple rolling mills.
4. W steel belt is a new type of mine support and tunnel support material, and its function is to form the bolt support network together with the bolt combination, and play the supporting role of rock wall or roadway. w steel strip is widely used in tunnel support of mine, cutting hole of working face, chamber and other fields, and has better effect on dealing with unstable surrounding rock.  

1. Model selection can be made according to different geological conditions and working environment;

2. The bending section modulus is increased by 37 times, and the downward section modulus is about 2.75 times that of the upward section modulus, so the anchor drill is used for upward jacking during installation;

3. Compared with other types of steel strips, W steel strips are more difficult to tear, and the steel is large, which is about 70 times higher;

4. Hardening during cold rolling to increase tensile strength by 12%-15%;

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

1. High strength alloy strip steel is used as raw material; Through cold pressing into W-shaped strip, cut according to the length requirements, and then punch holes;

2, with higher steel and strength;

3, W steel belt bending section modulus increased by 54 times;

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

1. Commonly used width: 180mm, 200mm, 220mm, 250mm, 280mm,300mm
2. Common thickness: 2.5mm,2.75mm,3.0mm Common aperture: 40mm*60mm 30mm*70mm
3. The length of w steel belt can be customized according to the actual needs of customers.
4. The w steel belt connects the scattered bolts to form an integral bearing structure, which significantly improves the overall effect of bolt support, and the application effect is better in incomplete roof rock. It has the advantages of reducing support cost, saving support steel and so on.
