HDG Self Drilling Anchor Bars with Corrosion Protection

Hot-dip galvanizing, also known as HDG coating, plays a vital role in strengthening construction hardware. It offers enhanced resistance to corrosion and wear, especially in aggressive environments. When applied to self drilling anchor bars, the zinc coating ensures that the bar holds its structural integrity over time, even when exposed to moisture, salt, or chlorides.Our HDG coating self drilling anchor bars are designed to meet these needs, offering superior corrosion resistance and ease of installation.

Advantages of Our Self Drilling Anchor Bars

Corrosion Resistance: The hot-dip galvanized (HDG) coating provides a robust barrier against corrosion, extending the lifespan of the anchor bars even in aggressive environments.
Integrated Design: Combining drilling, anchoring, and grouting into a single operation simplifies the installation process and reduces labor costs.
Versatility: Effectively adapts to different ground conditions, such as loose soil and broken rock formations, making it a reliable choice for diverse construction applications.
Thread Compatibility: Available in both R and T thread types, ensuring compatibility with different coupling and extension requirements.
Compliance with Standards: Manufactured in accordance with EN ISO 1461:1999, ensuring quality and reliability.

Product Benefits

Efficiency: Combining multiple steps into one operation reduces installation time and labor requirements.
Adaptability: The system can be tailored to various project needs, accommodating different lengths and diameters.
Durability: The HDG coating ensures long-term performance, even in corrosive environments.
Cost-Effective: Reduced installation time and extended service life contribute to overall cost savings.

Operation Process

The installation of self drilling anchor bars involves:

Drilling:The hollow anchor bar, fitted with a disposable drill bit, is installed into the ground using rotary percussive drilling.
Grouting: Simultaneously, grout is injected through the hollow core, filling voids and stabilizing the surrounding material.
Anchoring: Once the desired depth is reached, the bar is cut to length, and a plate and nut are installed to provide the necessary tension.

This integrated approach eliminates the need for casing and allows for installation in challenging ground conditions.

Application Scenarios

HDG coating self drilling anchor bars are suitable for a variety of applications:

Slope Stabilization: Providing support in unstable terrains to prevent landslides.
Tunneling: Reinforcing tunnel walls during excavation.
Foundation Support: Enhancing the stability of building foundations.
Retaining Walls: Strengthening structures that hold back soil or rock.
Mining Operations: Securing underground excavations and preventing collapses.
