7-wire prestressed concrete steel strand
This 7-wire prestressed concrete steel strand is a low-relaxation product with a 1x7 configuration, designed for high-strength applications in precast and post-tensioned concrete structures. The strand is available in tensile strengths of 1670 MPa, 1770 MPa, 1860 MPa, and 2000 MPa, meeting the requirements of ASTM A416, BS5896, and GB/T5224 standards. Its corrosion-resistant steel composition ensures durability in harsh environmental conditions, making it suitable for long-span bridges, high-rise buildings, and other critical infrastructure projects.
The strand consists of six outer wires helically wrapped around a single king wire, optimising load distribution and reducing stress concentration. Standard wire diameter for this configuration is 5.0 mm, 5.2 mm, or 5.3 mm, with typical cross-sectional areas of 140 mm² to 150 mm² depending on the grade. The surface is typically coated with a protective layer to enhance resistance to moisture and chloride exposure, which is critical for marine or coastal applications.
This product is primarily used in the construction of precast concrete elements such as beams, slabs, and piles, as well as in the post-tensioning of bridges and parking structures. Buyers include precast concrete manufacturers, civil engineering firms, and infrastructure developers. The strand is supplied in coils or reels, with typical packaging in waterproof wrapping and wooden or steel pallets for export. Confirm MOQ, coil weights, and incoterms with the supplier before ordering.

Sourcing 7-wire prestressed concrete steel strand from Tianjin Qiangbang Industrial Co., Ltd. - China Import Guide
Before ordering, verify the strand’s tensile strength grade and relaxation class against your project’s engineering requirements. Request mill test certificates (MTC) to confirm compliance with ASTM A416, BS5896, or GB/T5224, as these documents provide traceability and assurance of mechanical properties. Check that the supplier’s heat numbers and batch details are included for quality tracking.
Confirm logistics details such as coil weight, packaging type, and loading constraints for your shipment. Typical coil weights range from 1.5 to 3.0 tonnes, and packaging may include wooden or steel pallets with waterproof wrapping. Agree on Incoterms (e.g., FOB Tianjin) and payment terms (e.g., L/C or T/T) in advance to avoid delays. Lead times for steel strands can vary; request a production schedule aligned with your project timeline.
Conduct quality checks upon receipt, including visual inspection for corrosion, verification of coil weight, and measurement of wire diameter. For critical applications, arrange third-party inspection (e.g., SGS) to test tensile strength, elongation, and relaxation. Ensure all documentation, including certificates of compliance and origin, is complete and matches the shipment. Address any discrepancies with the supplier before acceptance.
