The Siam Industrial Wire Co., Ltd. (siw) supplies PC Wire that is manufactured from high carbon steel with carbon content between 0.60 % and 0.85 %, silicon 0.17 %‑0.37 % and manganese 0.40 %‑1.00 %. The wire is offered in diameters from 4 mm up to 9 mm, matching the dimensions commonly required for prestressed concrete reinforcement. Each strand is produced in plain, indented, chevron, spiral or crimped profiles, allowing designers to select the surface geometry that best suits their tensioning method. The product complies with Thai standards for prestressed concrete wire and is widely used in bridge decks, precast components and high‑rise building structures.
High carbon low‑relaxation steel wire provides superior tensile strength and maintains low creep under sustained loads, a property essential for long‑term structural performance. Typical tensile strength for this class of wire is around 1800 MPa, and the relaxation rate is usually below 0.5 % per 1000 hours, aligning with international expectations for prestressed applications. The wire is supplied either as coils with a standard coil diameter of 300 mm or as straight lengths, both packed in timber or steel drums to protect against corrosion during transit. Standard quality control includes tensile testing, dimensional inspection and surface defect checks according to GB/T5223 and ASTM A421.
Infrastructure contractors, bridge builders and structural engineering firms typically source this wire in bulk to meet project schedules. The supplier lists a minimum order quantity but does not disclose the exact figure, so buyers should confirm the MOQ directly with siw. Incoterms, payment terms and lead times are negotiated per order, with the supplier able to ship from its Bangkok facility to major ports worldwide.

Before placing an order, verify that the supplier can provide up‑to‑date test certificates for chemical composition, tensile strength and relaxation rate. Confirm that the wire conforms to the GB/T5223 or ASTM A421 standards required by your project specifications. Request a sample batch if possible to assess dimensional accuracy and surface finish.
Logistics for Thai‑origin steel wire typically involve shipment from the Bangkok port using either FOB or CIF terms, but the exact Incoterm should be agreed with the supplier. Lead times are not disclosed in the listing; ask the supplier for a realistic production and delivery schedule based on the required quantity. Payment terms are usually negotiated per transaction and may include a Letter of Credit or documentary collection.
Quality assurance should include third‑party inspection of tensile properties, dimensional tolerances and surface condition before loading. Arrange for pre‑shipment sampling or on‑site verification if the contract value justifies it. Ensure that the supplier can provide a Mill Test Certificate and a Declaration of Conformity for each shipment to satisfy import regulations.
