· ​Low-Profile Flat Geometry: Specifically engineered with an optimized, streamlined height profile to fit perfectly into thin structural concrete sections, narrow bridge webs, and flat slab edges where vertical clearance is severely limited.
· ​Inline Multi-Hole Stress Distribution: Features a precision-spaced horizontal hole layout that distributes concentrated tendon forces evenly across the flat bearing plate, preventing localized concrete cracking.
· ​High-Strength Metallurgical Integrity: Cast and forged from superior alloy steel or high-grade ductile iron, providing exceptional compressive strength and fatigue resistance under continuous cyclic loads.
· ​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 specialized civil and building engineering sectors:
· ​Bridge Construction: Transverse post-tensioning of bridge decks, thin-web box girders, and segmentally constructed superstructures.
· ​Commercial & Residential Buildings: Flat-plate floor slabs, transfer beams, and architectural thin-wall structures requiring minimal tendon protrusion footprint.
· ​Specialized Civil Works: Containment walls, underground tunnel linings, and specialized structural retrofitting projects.
​Q: How many strands does this flat anchor head accommodate?
A: We offer standard flat anchor configurations holding 2, 3, 4, or 5 strands in a horizontal inline arrangement, tailored for both 12.7 mm (0.5") and 15.24 mm (0.6") PC strands.
​Q: Why choose a flat anchor head over a standard round anchor?
A: Flat anchor heads are specifically designed for applications with strict vertical height limitations, such as thin bridge webs or flat slabs, allowing proper tendon distribution without compromising concrete cover thickness.
​Q: What is the standard export packaging and transport safety?
A: Flat anchor blocks and matching wedge sets are treated with anti-rust protection, packed neatly onto heavy-duty wooden pallets, and secured with steel strapping to prevent transit damage.
