Special screws: special screw production method

With the increase of transportation, energy and other infrastructure construction, in the tunnel, basement and slope, as a rock bolt technology to give full play to the self-stabilizing ability of rock mass has been developed rapidly, the amount of rock bolt is increasing day by day, showing broad prospects for development. Bolting is an economical and effective method to improve the stability of geotechnical engineering. Among them, the quality of the hollow anchor rod is reliable, the anchoring effect and reinforcement effect are much better, and its application is more and more extensive. Then, let's learn about the production method of the special screw below!

What is the anti-corrosion method of special screws?

Special screws are made of metal. There are four main methods to prevent metal corrosion, namely the nature of the material itself, the environment used, the interface between data and the environment, and the design of improved metal structures. If a complete corrosion-resistant alloy is used to manufacture a special screw, it is not realistic in economic concept unless there are special requirements, or completely isolate the environmental factors that cause corrosion on the surface of the special screw, which may not be feasible in practice or may be very difficult.
