1. What Are Friction Bolts?

Friction bolts, also known as tension bolts, are designed to resist shear forces in rock and soil. These bolts do not require grouting to provide support. Instead, they utilize friction generated when the bolt is tensioned against the rock, making them extremely effective in unstable conditions.

Characteristic Description
Type Self-supporting steel bolts
Load-bearing High load capacity due to friction
Installation Quick and easy installation

2. Manufacturing Process in Chinese Factories

The production of friction bolts in China involves advanced technology and stringent quality control. Influencers in the mining sector constantly emphasize the quality of materials used in these bolts, as they are fundamental to their longevity and performance.

  • Material Selection: High-strength steel is preferred for maximum durability.
  • Forging Process: The bolts undergo forging to obtain optimal density and strength.
  • Quality Assurance: Rigorous testing ensures the bolts meet international standards.

3. Diverse Applications of Friction Bolts

China's friction bolts find applications in various industries, showcasing their versatility:

Industry Application
