Steel Strand for Prestressed Concrete

Premium PC Steel Strand for Prestressed Concrete Construction

Our prestressed concrete (PC) steel strand is the backbone of modern post-tensioned and pre-tensioned concrete structures. Manufactured from high carbon steel wire (SWRH77B / SWRH82B), our strand delivers the high tensile strength and low relaxation performance that engineers and contractors depend on.

Product Specifications:
• Construction: 1×3 wire, 1×7 wire configurations
• Standards: ASTM A416, BS 5896, EN 10138-3, AS/NZS 4672, GB/T5224
• Diameter range: 9.3mm – 21.8mm
• Tensile strength: Up to 1860 MPa (Grade 270 equivalent)
• Relaxation (1000h): ≤ 2.5% (low relaxation grade)
• Elongation at maximum load: ≥ 3.5%
• Initial load: ≤ 70% of breaking strength
• Raw material: SWRH77B / SWRH82B high carbon steel rod (non-alloy)
• Coil weight: 2 – 3.5 metric tons

Why Our Strand Stands Out:
Consistent Quality – Every strand is manufactured under strict ISO-quality processes with continuous monitoring of tensile strength, relaxation, and dimensional accuracy. No surprises on the job site.
Low Relaxation Performance – Our patented heat treatment ensures minimal prestress loss over time, maintaining structural integrity for the design life of your project.
Clean Surface– Each strand is free of rust, oil, and contaminants, ensuring proper bond with concrete grout in post-tensioning applications.

Applications:
• Post-tensioned bridges and highway structures
• Precast concrete beams and girders
• Building floor slabs and foundation slabs
• Ground anchors and soil nail walls
• Nuclear containment structures
• Silos, tanks, and other circular structures
• Crane beams and industrial roofing

Packaging & Delivery:>
Supplied in heavy-duty coils weighing 2-3.5 tons each, securely strapped and protected with rust-inhibiting wrapping for safe ocean transport.
