· ​Symmetric Circular Stress Distribution: Features an optimized radial hole arrangement that distributes massive concentrated tendon forces symmetrically across the circular bearing plate, preventing eccentric loading and concrete cracking.
· ​High-Strength Metallurgical Integrity: Cast and forged from superior ductile iron or alloy steel, providing exceptional compressive strength and structural rigidity to withstand extreme cyclic and static loads.
· ​Precision Conical Wedge Bores: Each individual tendon hole is precision-machined with a matching taper, ensuring perfect 360-degree wedge seating and absolute slip-resistance under ultimate tension.
· ​Full Batch Traceability & QC: Manufactured under strict ISO 9001 quality frameworks. Each production lot undergoes proof-loading, hardness verification, and rigorous dimensional inspection.
​Essential heavy structural components deployed across major civil and building engineering sectors:
· ​Highway & Railway Bridges: Continuous cast-in-place box girders, precast segmental bridges, extradosed bridges, and cable-stayed anchorage zones.
· ​High-Rise & Heavy Commercial Buildings: Massive transfer girders, podium foundation mats, and core-wall post-tensioning systems.
· ​Specialized Heavy Infrastructure: Nuclear containment structures, LNG storage tanks, large-span industrial roofs, and dam stabilization anchors.
​Q: How many strand holes are available in these round anchor heads?
A: We offer a comprehensive range of standard circular anchor configurations accommodating anywhere from 2 strands up to 55 strands (suitable for both 12.7 mm and 15.24 mm PC strands).
​Q: What auxiliary components are required for a complete round anchor assembly?
A: A complete multi-strand round anchorage system typically includes the circular anchor head, matching multi-piece wedges, a matching spiral reinforcement (bursting cage), and a steel/plastic trumpet.
​Q: What is the standard export packaging and transport safety?
A: Anchor blocks are treated with anti-rust protection, securely packed onto heavy-duty wooden pallets, and fastened with steel strapping to prevent transit damage during international freight.
