W-Shaped Steel Strip

Product Details

W-shaped steel strip is a new type of mine support and tunnel support materials, the product can be used with various anchor rods to organize a combination of anchor bracket, through which it can be dispersed multiple anchor rods connected to form a whole bearing structure, significantly improve the overall effect of the anchor, in the incomplete roof rock layer, the effect of the treatment of unstable surrounding rock is good.

W-shaped steel strip is named because its cross-section resembles the letter "W", and the material of W-shaped steel strip is Q235.

W steel strip, also called top plate steel strip, is a steel section product made of longitudinally sheared strip steel as raw material and formed by continuous cold bending and roll forming in multiple rolling mills.

W-shaped steel strip is a new type of mine support and tunnel support materials, the role of the combination with the anchor rods to form a common anchor support network, play a rock wall or tunnel support.W steel belt is widely used in mine tunnel, face cut eye, refuge and other areas of tunnel support.

Specifications and Parameters

Features of W-shaped steel strip:

1. According to different geological conditions and operating environments, we can choose the type of steel belt;

2. Flexural section modulus is 37 times higher, and the downward section modulus is about 2.75 times higher than the upward section modulus, so when installing it, it is tightened upward by using an anchor drilling rig;

3. Compared with other types of steel strip, W steel strip is more resistant to tearing and has a large steel degree, which is about 70 times higher;

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

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

W steel strip four major features:

1. Raw material adopts high-strength alloy steel strip; it is turned into W-type strip through cold pressing, truncated according to the length requirement, and then perforated;

2. It has higher steel and strength;

3. W steel strip flexural section modulus increased 54 times;

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

Product Description

W-shaped steel strip is a new type of mine support material.W-shaped steel strip is a new type of mine support material, W-shaped steel strip adopts the thickness of 3-5mm width 180-320mm rolled steel plate, after cold bending into W shape, in the middle of the W-shaped steel strip processed with the anchor spacing equal to the anchor holes in the steel belt, W-shaped steel strip to the dispersed multiple anchors linked together to form a whole load-bearing structure, significantly improve the overall effect of the anchor support, the application of the incomplete top plate rock is more effective. It is better applied in the incomplete roof rock. It has the advantages of reducing support cost and saving support steel.

Usage of W-shaped steel strip

W-shaped steel strip can be combined with various kinds of anchor rods to form an anchor plate support, W-shaped steel strip that is, through the W-shaped steel strip to dispersed multiple anchor rods linked together to form a whole load-bearing structure, W-shaped steel strip is widely used in coal mine tunnel, working face cut eye, mine chamber and other areas of the tunnel support, the effect of dealing with the unstable perimeter rock is better.
