· ​​Optimized 0.5" Flat-Plate Design: Specifically engineered for thin slab unbonded post-tensioning, providing maximum bearing surface area to distribute concentrated tendon forces safely into the concrete matrix.
· ​Precision 3-Piece Wedge Locking: Equipped with matched 3-piece high-carbon steel wedges that bite securely into the 12.7 mm strand under tension, guaranteeing zero slippage and permanent load retention.
· ​Comprehensive Corrosion Defense: Features integrated plastic encapsulation pockets and protective grease caps that seal the stressing tail against moisture and chemical ingress in aggressive slab environments.
· ​Full Batch Traceability & Quality Control: Manufactured under strict ISO 9001 quality frameworks. Each production lot undergoes proof-loading, hardness testing, and dimensional verification.
​Essential structural components deployed across modern commercial and residential construction:
· ​Commercial & Residential Floor Slabs: Unbonded post-tensioned flat plates, waffle slabs, and long-span office building floors.
· ​​Multi-Story Parking Structures: High-traffic parking deck slabs requiring high fatigue resistance and crack control.
· ​Foundation & Transfer Structures: Heavy basement mats, transfer girders, and podium deck stabilization systems.
​Q: Does this monostrand anchor comply with PTI unbonded post-tensioning specifications?
A: Yes. Our 0.5" unbonded anchoring systems are manufactured and tested to meet or exceed Post-Tensioning Institute (PTI) and ASTM standards for structural concrete applications.
​Q: What components are included in a complete monostrand anchor assembly?
A: A standard assembly typically includes the anchor casting (plate), a set of 3 matching high-strength wedges, and a protective plastic pocket/cap for encapsulation.
​Q: What is the standard export packaging and transport safety?
A: Assemblies are neatly boxed or palletized with protective wrapping to prevent mechanical damage or thread/taper contamination during international shipping.
