Stainless Steel Strip Suppliers
Advantages include the following:
Using high strength alloy steel strip as raw material can provide higher rigidity and strength. Provides higher rigidity and strength than ordinary steel strip. The flexural section modulus of W steel strip is 54 times higher, indicating superior performance in flexural resistance. During cold pressing, the hardening effect of W steel strip gives it a higher tensile strength, which can be increased by 28-46%.
Performance Description
Material: The steel strip is made of rolled steel plate with a thickness of 3-5mm and a width of 180-320mm, which is cold-bent into a W-shape and processed in the middle to produce anchor holes equal to the spacing of the anchors.
Function: The W-shaped steel belt can link the scattered anchor rods together to form a whole load-bearing structure, thus significantly improving the overall effect of anchor support.
Advantage: The effect is more significant when applied in incomplete roof rock, which helps to reduce the cost of support and save support steel.

Product Use
W steel belt can be used in combination with various types of anchor rods to play a role in anchor disk support. By linking the scattered anchor rods together to form a whole load-bearing structure, W-belts are widely used for tunnel support in underground coal mines, face cuttings, mine chambers and other areas. Especially when dealing with unstable surrounding rocks, W-belts can play a better effect and provide more reliable support guarantee.
The steel belt products have the following characteristics:
1. Strong applicability: suitable models can be selected according to different geological conditions and operating environments, which improves the scope of application.
2. Excellent flexural performance: the flexural section modulus is increased by 37 times, which helps to improve the installation efficiency and firmness by using the anchor drilling rig to jack upward during installation.
3. High strength: Compared with other types of steel strips, W steel strips are less prone to tearing and have a greater degree of steel, which is about 70 times higher, making them more durable and long-lasting.
4. Strong tensile properties: Hardening during the cold rolling process increases tensile strength by 12%-15%, improving product life and safety.
5. Economical: with high cross-section utilization, saving material costs, relatively low price, with economic.
