In coastal and industrial zones worldwide, engineers grapple with corrosion-induced failures that compromise structural safety and inflate maintenance costs. Addressing these persistent issues, SupAnchor, Asia's top manufacturer and exporter of self-drilling anchors, has launched its stainless steel self-drilling hollow anchor. This innovative product leverages a proven 3-in-1 design to deliver superior corrosion resistance, targeting projects in harsh environments where durability is paramount. As infrastructure demands grow in sectors like marine engineering and chemical plants, this anchor aims to set new standards for geotechnical reinforcement systems.
The stainless steel self-drilling hollow anchor embodies SupAnchor's core 3-in-1 principle, integrating a sacrificial drilling rod, injection tube, and reinforcing bar into a single ribbed hollow bar. This design enables simultaneous drilling and grouting, eliminating the need for separate casings and reducing installation time in unconsolidated soils. Made from stainless steel, the anchor inherently resists rust, pitting, and chemical degradation, ensuring long-term performance in saltwater, humid, or industrial settings. Key technical parameters from the representative model R32SS/15 highlight its robustness:
| Parameter | Value |
|---|---|
| Outside Diameter | 32 mm |
| Ultimate Load | ≥405 kN |
| Yield Load | ≥300 kN |
| Corrosion Resistance | Stainless steel material |
| Thread Type | ISO 10208 - R32 |
These specs solve critical engineering challenges by providing high tensile strength and corrosion resistance, reducing the risk of anchor failure in projects like port foundations or chemical plant reinforcements. The optimized rib structure, with a relative rib area of 0.21-0.33, enhances bonding with grout while minimizing soil disturbance, keeping crack widths below 0.1 mm under maximum load. This self drilling anchor system ensures reliable load-bearing capacity, comparable or superior to carbon steel alternatives, making it a versatile drill-and-grout bolt for demanding applications.
The stainless steel variant is tailored for environments where traditional anchors falter due to corrosion. Its applications span various high-risk sectors:
This hollow bar anchor addresses geotechnical safety concerns by offering a durable solution that reduces lifecycle costs and enhances project longevity.
SupAnchor's introduction of the stainless steel self-drilling anchor underscores its commitment to innovation and professionalism in the geotechnical sector. As a leading soil nail system manufacturer, the company leverages extensive R&D and ISO certifications (e.g., ISO 10208) to ensure product reliability. This anchor complements SupAnchor's anti-corrosion portfolio, which includes hot-dip galvanizing and SupCoating, showcasing a collaborative approach to meeting diverse project needs. In global infrastructure projects, from tunneling in Europe to mining in the Americas, this product supports safety and efficiency, aligning with trends toward sustainable and low-maintenance solutions. The brand's influence is evident in its accessory compatibility, such as with SW46 nuts and D42 couplers, simplifying logistics and installation for engineers worldwide.
In conclusion, the stainless steel self-drilling hollow anchor represents a significant advancement in geotechnical reinforcement systems, blending technical excellence with practical adaptability. By prioritizing corrosion resistance and mechanical performance, SupAnchor reinforces its position as an innovative partner in global engineering, ready to tackle the toughest environmental challenges with professional-grade solutions.
