Astm Standard 12.7mm Steel Pc Strand
This ASTM A416 compliant 12.7 mm steel PC strand from Henan Hengxing PC Steel Product Co., Ltd is a seven-wire low-relaxation prestressing strand manufactured from high-carbon steel. The configuration consists of one central wire wrapped helically by six outer wires, cold-drawn and stress-relieved to achieve the high tensile strength and low relaxation properties required for post-tensioned concrete structures. The 12.7 mm nominal diameter is a standard size for bridge decks, parking structures and high-rise floor slabs in international construction markets.
Low-relaxation strand is characterised by stress loss under sustained load that is substantially lower than stress-relieved (normal relaxation) strand, typically maintaining 90 percent or more of initial prestress after 1000 hours at 70 percent of breaking load. The high carbon steel composition, typically 0.75 to 0.85 percent carbon with manganese and silicon additions, provides the wire drawability and final strength. ASTM A416 specifies minimum breaking strength of 184 kN for 12.7 mm Grade 270 low-relaxation strand, with minimum elongation of 3.5 percent in 610 mm gauge length and maximum relaxation of 2.5 percent after 1000 hours.
Infrastructure contractors, precast concrete manufacturers and post-tensioning specialists are the primary buyers. The supplier notes cooperation with national railway projects and cites China National construction steel quality supervision and test centre certification. Annual production capacity is stated at 300,000 tons. Buyers should confirm current availability, coil weights and whether the cited ISO management certification is current and scope-appropriate for PC strand production.

Sourcing Astm Standard 12.7mm Steel Pc Strand from Henan Hengxing PC Steel Product Co., Ltd - China Import Guide
Before ordering, verify that Henan Hengxing can supply current mill test certificates for the specific coil lots you will receive, with chemical composition, tensile test results, relaxation test data and modulus of elasticity traceable to heat numbers. Confirm that the ASTM A416 compliance claimed is supported by accredited laboratory test reports, not just internal factory certificates. Request the ISO certificate scope to ensure it explicitly covers PC strand manufacturing, and check whether the China National construction steel quality supervision and test centre certification is current and available for buyer review.
Confirm Incoterms, port of shipment, typical coil weights and container loading configurations, as these are not stated in the listing. Zhengzhou is inland, so clarify whether delivery is from factory or from a coastal port warehouse, and who arranges inland haulage. Lead time, MOQ and payment terms must be negotiated directly. Typical payment structures for Chinese steel exports include 30 percent TT advance with LC at sight for balance, but terms vary by buyer history and order volume.
On receipt, inspect coil tags for heat number traceability, check for surface rust or mechanical damage that could affect grout bond, and verify coil dimensions suit your dereeling equipment. Retain samples from each heat for independent tensile and relaxation testing if the project requires third-party verification. Store coils under cover to prevent corrosion, and rotate stock on a first-in-first-out basis as strand properties are stable but surface condition degrades with outdoor exposure. Request packing lists and certificates in advance to expedite customs clearance at destination.
