In the face of escalating demands for resilient infrastructure across Europe and the Americas, SupAnchor, Asia's premier manufacturer and exporter of self-drilling anchor systems, has introduced a groundbreaking stainless steel variant of its self-drilling hollow anchor. This innovation targets high-corrosion environments, such as coastal zones and industrial sites, where traditional anchoring solutions often falter due to rust and degradation. As global projects in tunneling, mining, and geotechnical safety expand, this new product underscores SupAnchor's role in advancing durable reinforcement systems, leveraging its ISO-certified R&D to meet rigorous engineering standards.
The stainless steel self-drilling hollow anchor adheres to SupAnchor's core "3-in-1 principle," which integrates a sacrificial drilling rod, injection tube, and reinforcing bar into a single unit. This design eliminates the need for separate casing systems, enabling simultaneous drilling and grouting—a critical advantage in unconsolidated or cohesive soils where efficiency and safety are paramount. Key technical features include inherent corrosion resistance from stainless steel material, optimized rib structures for enhanced bonding with grouting materials, and compatibility with standard ISO thread specifications for quick on-site connections. These attributes solve common engineering challenges by reducing installation time, minimizing soil disturbance, and ensuring long-term structural integrity in corrosive settings.
To illustrate, the R32SS/15 model, a representative stainless steel variant in the R thread series, offers robust mechanical performance while prioritizing durability. Its specifications address the need for reliable load-bearing capacity in harsh conditions, as shown in the table below:
| Parameter | Value |
|---|---|
| Outside Diameter (mm) | 32 |
| Internal Diameter (mm) | 14 |
| Cross Sectional Area (mm²) | 509 |
| Ultimate Load (kN) | ≥405 |
| Yield Load (kN) | ≥300 |
| Weight (kg/m) | 4.00 |
| Thread Type | ISO 10208 - R32 / Left or Right |
| Steel Type | Stainless Steel |
| Elongation % | A100mm ≥6% / Agt ≥5% / A200mm ≥6% |
This self-drilling anchor bolt maintains tensile strength and yield load comparable to carbon steel models, ensuring it meets the demands of geotechnical reinforcement systems without compromising on corrosion resistance. The hollow bar anchor design, coupled with stainless steel's durability, translates to reduced maintenance costs and extended service life, making it a cost-effective solution for projects requiring permanence.
The stainless steel self-drilling hollow anchor is engineered for diverse application scenarios where corrosion poses a significant threat. Key uses include coastal and marine engineering, such as port terminal foundations and sea wall stabilization, where saltwater exposure necessitates robust anti-corrosion measures. In chemical and industrial projects, this drill-and-grout bolt resists degradation from chemical vapors, supporting infrastructure in plants and wastewater facilities. Additionally, it excels in humid outdoor environments like slope stabilization in tropical regions or water conservancy projects, preventing rust-related failures. For permanent structures—from historical buildings to nuclear power plant supports—this anchor ensures long-term safety and reliability, aligning with SupAnchor's portfolio of soil nail systems and ground anchor bolts designed for harsh conditions.
SupAnchor's introduction of this stainless steel variant highlights its commitment to innovation and collaboration in the global infrastructure sector. By addressing corrosion challenges, the product enhances geotechnical safety in tunneling, mining, and construction projects, contributing to sustainable development. The company's position as the No.1 manufacturer in Asia is bolstered by its extensive R&D, ISO certifications, and involvement in global projects that demand high-performance reinforcement systems. This self-drilling anchor system not only meets technical specifications but also conveys a brand message of professionalism and reliability, fostering partnerships with engineers and contractors worldwide. As infrastructure demands grow, SupAnchor's focus on advanced hollow bar anchors and related technologies positions it as a key player in ensuring resilient and durable solutions for future generations.
In summary, SupAnchor's stainless steel self-drilling hollow anchor represents a significant advancement in geotechnical reinforcement, offering superior corrosion resistance and engineering adaptability. With its proven technical parameters and broad application scope, this product underscores the brand's role in driving innovation and safety across industries, from coastal engineering to industrial zones, reinforcing its legacy as a trusted manufacturer in the self-drilling anchor bolt market.
