What is the "Four-Piece Set" of Prestressed Anchors? -- Direct from the Source, Quality Builds a Solid Foundation for Projects

The "Four-Piece Set" of prestressed anchors refers to the complete anchoring system in engineering, referring to the four core components: the anchor ring, clip, anchor plate, and spiral rebar. As a professional manufacturer, we understand that the quality of these four components is directly related to project safety. Therefore, we rigorously control every step of the process, from raw material selection to processing, to ensure that each product withstands the test of actual operation. The functions of this four-piece set are as follows:

1. Anchor Ring

The anchor ring, serving as the "skeleton" of the entire anchor system, is typically a ring-shaped structure with a tapered hole. Forged from high-strength alloy steel, it undergoes multiple heat treatment processes to enhance its toughness and load-bearing capacity, ensuring it can stably withstand the immense tensile forces of the prestressed tendons, laying a solid foundation for subsequent force transmission. As the "first stop" for force transmission, our anchor ring's dimensional accuracy is controlled to within 0.02mm, ensuring a perfect fit with the clips and ensuring the stability of the project.

2. Clips

The clips are wedge-shaped (or tapered), typically consisting of two or three clips, and feature precise serrations on the inside. Our clips are precision-milled from a specialized alloy. The depth and angle of the serrations are optimized through thousands of trials, ensuring a secure hold on the prestressed tendons after tensioning, eliminating the risk of retraction. Our factory can customize the serration specifications to meet customer needs, ensuring reliable anchoring of tendons of varying diameters and contributing to project safety.

3. Anchor Plate

The anchor plate connects the anchor to the concrete. We stamp and form it from high-strength steel plate, with the groove depth and angle precisely matched to the anchor ring dimensions, ensuring a smooth force transfer path. Our anchor plate's surface undergoes a special rust-proof treatment, ensuring long-term stable operation even in humid environments. It effectively distributes concentrated tension evenly throughout the concrete, preventing localized cracking and ensuring overall performance.

4. Spiral Rebar

Spiral rebar is used to reinforce the anchor area. Our factory cold-draws high-carbon steel wire, ensuring uniform spiral pitch and precise number of turns. Once installed, it provides strong circumferential restraint to the concrete. Our proprietary winding equipment ensures consistent tension across each spiral, effectively resisting concrete cracking under high stress, significantly improving the durability of the anchor area and ensuring the longevity of the project.

The Synergistic Effect of the Four-piece Set

After the prestressed tendons are tensioned to the designed stress, our clips tightly engage the anchor rings. The anchor rings precisely transmit the force to the matching anchor pads, which in turn evenly distribute the force to the concrete. The spiral bars simultaneously exert a restraining effect. The smoothness of this coordinated action is due to our factory's strict dimensional tolerances for the four-piece set (within a tolerance of no more than 0.1mm for the entire set). Our products are widely used in critical applications such as bridges, high-rise buildings, and water conservancy projects, making us a trusted supplier for our customers.

As a source manufacturer, we promise that every four-piece anchor set undergoes rigorous quality inspections, including tensile and fatigue testing, and no substandard products leave our factory. We work directly with customers, eliminating intermediaries and providing high-quality products at a more affordable price.
