About our company
Zhongfu is committed to providing support materials that meet the mining, quarrying, and construction requirements of customers, especially in terms of quality, cost, and timely delivery, ensuring the safety of underground workers, saving costs for customers and making them worry free.
In pursuing these goals, ZhongFu will utilise all available resources to optimise the interests of stakeholders, whilst improving the life of its employees and the community at large.
Application Principles
The W steel belt is used to connect scattered 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.
After years of development, on the basis of the company's high penetration express delivery network covering the country and major countries and regions around the world, we provides customers with integrated supply chain solutions through procurement, production, circulation, sales and after-sales.

Instructions for use
At present, the mining depth of W steel belt has reached more than 500-1000 meters in the mines produced by domestic group companies, and the ground stress, stress and deformation of surrounding rock are complex and diverse. A single anchor bolt support can no longer meet the requirements of roadway support with broken roof, composite roof and large roof pressure, and the anchor beam system composed of anchor bolt and W steel belt can effectively control the roof. At the same time, it can also be used to support the roadway and chamber with large fracture. The anchor beam system not only solves the problem of roadway support, but also can be used in other roadway and chamber support with large section, and can also be used in the reinforcement of landslide, embankment and dam.
use to
W steel strip is a new type of mining support material. The W steel strip is made of 3-5mm thick and 180-320mm wide rolled steel plates, which are cold-formed into a W-shaped steel strip. In the middle of the W steel strip, a W steel strip with anchor holes equal to the distance between anchor rods is processed. The W steel strip can be combined with various anchor rods to form an anchor plate support. The W steel strip connects multiple scattered anchor rods through the W steel strip to form an overall load-bearing structure. The W steel strip is widely used in coal mine underground tunnels, working face cut holes, chambers, and other fields of tunnel support, and has a better effect on dealing with unstable surrounding rock.
superiority
Technical advantages of W steel strip compared to flat steel strip:
1. The bending section modulus of W steel strip is increased by 37 times.
2. The stiffness has increased by about 70 times.
3. The hardening effect during the cold rolling process of W steel strip increases the tensile strength by 12% -15%.
