2.Applications
3. Product Structure
Twisted anchor bolt is composed of the anchor rod body, sleeve, anchor head, twisted ending and anchoring accessories. Its unique mechanical structure improves the bonding force between anchor rod and surrounding rock/soil to ensure safety and stability of building construction.
4. Advantages
4.1 Strong Tensile Strength: HRB400 steel material provides great tensile strength enabling better reinforcement in geotechnical engineering.
4.2 Improved durability: With improved corrosion resistance with optional surface treatment like galvanizing, paint spraying or plastic coating, the anchor bolts can last longer.
4.3 Better anchoring effect: The twisted rod end maximizes surface contact and bonding between anchor bolt and the anchoring medium to improve support reliability.
4.4 Specification Flexibility: Connectors are available in different diameters, lengths and with multiple head shapes. Surface treatment can also be customized to meet project requirements.
5. Installation Tips
5.1 Design: Select the appropriate anchor bolt model based on the engineering need and geological conditions.
5.2 Production: During manufacturing, material selection, processing and production should follow the technical standards.
5.3 Installation: During construction, follow the drawings and the installation process requirements to avoid uneven length-cutting, inclined installation and screw loose.
5.4 Maintenance: Inspection and maintenance is recommended during usage to ensure long-term use.
