The 7‑wire PC Strand offered by The Siam Industrial Wire Co., Ltd. (siw) is manufactured from high carbon, low relaxation steel wire with a carbon content of 0.6‑0.85 %. The strand is twisted from seven individual wires and is supplied in diameters ranging from 7.9 mm to 18 mm. Standard grades include 270 ksi (1860 MPa) and the product conforms to ASTM A416 or equivalent international specifications. This information is taken directly from the supplier’s technical description.
Four strand profiles are available - plain, indent, chevron and compact - each designed to meet the demands of pre‑stressed and post‑tensioned concrete structures. In the industry, a typical tensile strength for grade 270 steel strand is 1860 MPa and low relaxation values are usually below 5 % loss after 1000 hours at 80 °C. Suppliers often apply a galvanized or epoxy coating as a typical corrosion‑protective measure, although the exact finish should be confirmed with the factory. These characteristics make the strand suitable for high‑load applications.
The strand is widely used in bridges, multi‑storey parking structures and high‑rise building frames, where contractors and structural fabricators require reliable load‑bearing capacity. The product is shipped either coiled or drummed, allowing containerised bulk export to overseas projects. Buyers should verify the required diameter, grade, coating type and any certification documents before placing an order, and discuss incoterms, payment and lead‑time directly with the supplier.

Before confirming an order, verify the exact strand diameter, grade, carbon content and any surface coating. Request the relevant test certificates, such as tensile strength and relaxation test results, to ensure the material meets project specifications. Confirm that the product complies with ASTM A416 or the equivalent standard required for your region.
The PC strand is shipped in coils or drums, allowing it to be loaded into standard 20‑ or 40‑foot containers. Discuss the preferred incoterm - for example FOB Bangkok or CIF - and ask the supplier to provide an estimated lead‑time based on your order volume. Payment terms and any required letters of credit should also be clarified early in the negotiation.
For quality assurance, arrange a third‑party inspection at the loading port or request a pre‑shipment sample. Verify the mill test report, coating integrity and any anti‑rust treatment applied. Proper documentation, including a certificate of conformity and packing list, will help streamline customs clearance and project acceptance.
