In response to the increasing demands of infrastructure projects, SupAnchor has introduced its Grade 75 self-drilling hollow anchor bars, designed to address complex geological conditions in slope stabilization and tunneling. This innovation comes as part of the company's commitment to providing reliable and efficient solutions for hydropower stations and other large-scale engineering ventures across Europe and America. The new product aims to replace traditional solid threaded bars, offering enhanced bond performance and compatibility with existing systems.

The Grade 75 self-drilling hollow anchor bars are produced according to ASTM A615 standards, featuring a continuous T-thread design that increases rib area for superior bond performance in concrete. This design makes them ideal for replacing solid bars in challenging environments where efficiency and cost savings are critical. Key mechanical properties ensure reliability in various applications:
| Property | Value |
|---|---|
| Elongation | ≥ 6% |
| Yield Load | 147 kN (33 kips) |
| Ultimate Load | 196 kN (44 kips) |
| Weight | 2.6 kg/m (1.75 lbs/ft) |
| Thread Orientation | Left-hand thread |
These specifications allow the bars to handle high stress loads, making them suitable for critical reinforcement tasks. The self drilling anchor system integrates seamlessly with SupAnchor's existing product lines, ensuring easy installation and reduced downtime on construction sites. By optimizing the drill-and-grout bolt process, engineers can achieve faster project completion while maintaining safety standards.
The Grade 75 hollow bar anchor is particularly effective in geotechnical applications such as slope stabilization for hydropower stations, tunneling operations, and foundation reinforcement. In Europe and America, where aging infrastructure and new development projects demand robust solutions, this product offers a versatile option for soil nail systems and ground anchor bolt installations. Its cost-effectiveness stems from reduced material usage and labor, aligning with global trends toward sustainable and efficient construction practices.
As the demand for reliable geotechnical reinforcement systems grows, SupAnchor's innovation positions it as a key player in enhancing geotechnical safety and project longevity. The self drilling anchor bolt technology supports large-scale ventures by minimizing environmental disruption and improving structural integrity.
SupAnchor's development of the Grade 75 bars underscores its dedication to R&D and quality assurance, backed by ISO certifications and participation in global projects. The company emphasizes a collaborative approach, working closely with engineers and contractors to tailor solutions for specific needs. This focus on innovation has led to a reputation for professionalism in the geotechnical sector, with products designed to meet rigorous international standards.
Looking ahead, SupAnchor aims to expand its influence in markets such as tunneling, mining, and renewable energy infrastructure. The brand message of "Professional, Innovative, Collaborative" resonates through its product lines, including the self drilling anchor system, which continues to evolve based on feedback from field applications. By investing in cutting-edge technology, SupAnchor contributes to safer and more efficient construction practices worldwide.
