In the challenging geological landscapes of European hydropower projects, engineers confront steep slopes and unstable rock formations that threaten infrastructure integrity. SupAnchor, a prominent player in the anchor system industry, has stepped in with its Grade 75 self-drilling hollow anchor bars, providing a robust solution for slope stabilization and geotechnical reinforcement. This innovation addresses critical engineering needs by combining efficiency with high-performance standards, ensuring safety and durability in demanding environments.

The installation process at hydropower sites involves direct drilling into varied substrates, where the self drilling anchor system excels by eliminating pre-drilling steps, thus reducing labor costs and project timelines. SupAnchor's Grade 75 bars are engineered to ASTM A615 standards, featuring a continuous T-thread design that enhances rib area for superior bond performance in concrete and grout. Key mechanical properties ensure reliability under load, making these bars a versatile component in geotechnical reinforcement systems.
| Parameter | Specification |
| Material Grade | 75 (ASTM A615) |
| Elongation | ≥ 6% |
| Yield Load | Approximately 147 kN (33 kips) |
| Ultimate Load | Approximately 196 kN (44 kips) |
| Weight | Approximately 2.6 kg/m (1.75 lbs/ft) |
| Thread Orientation | Left-hand thread |
These specifications enable the self drilling anchor bolt to withstand significant tensile forces, ideal for applications where stability is paramount. The left-hand thread facilitates installation in specific geological settings, enhancing adaptability. Additionally, corrosion protection measures, such as galvanization or epoxy coatings, are standard, extending service life in harsh conditions. Compatibility with SupAnchor's existing R and T thread products ensures seamless integration, reducing downtime on construction sites.
The hollow bar anchor technology demonstrates broad utility across various geotechnical projects. Key applications include:
SupAnchor's products are designed for easy deployment, with diameters ranging from 25mm to 51mm and lengths customizable up to 12 meters, catering to diverse project scales. This flexibility makes the self drilling anchor bolt a preferred choice for engineers worldwide.
