Steel Wire
Steel Wire Manufacturer and Supplier in Indonesia
Steel wire is drawn from wire rod to precise diameters and finished with galvanized, annealed or bright surfaces for binding, fencing, construction and manufacturing. Sino East Steel is a steel wire manufacturer and supplier based in Tianjin, China, exporting to Indonesia and more than 50 countries for over 18 years. As a direct factory supplier with a 65,000 m2 production base and 500,000 tons of annual capacity, we deliver to Indonesian importers, distributors, contractors and project companies with complete documentation, including the Mill Test Certificate (MTC) per EN 10204 3.1 on every shipment.
Indonesian buyers choose our steel wire because every batch is tested in our ISO 9001:2015 certified quality system, packed seaworthy and shipped to Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), Belawan (Medan) and Makassar within 18-25 days after production. Third-party inspection by SGS, BV or TUV can be arranged at the factory or at the destination port, and SNI documentation support is available for regulated applications.
What Is Steel Wire?
Steel wire is produced by cold drawing wire rod (SAE1006, SAE1008) through dies to reduce diameter and increase strength, then finished by galvanizing, annealing or bright processing. It is the base material for binding wire, tie wire, fencing mesh, nails, springs, cable armoring, wire rope and a wide range of industrial products.
Indonesian construction suppliers, fence manufacturers and industrial users buy galvanized and black annealed wire from Sino East Steel in diameters from 0.5 mm to 6.0 mm, on spools, coils or cut lengths, with consistent tensile strength and coating quality batch after batch.
Standards, Grades and Specification Range
Our steel wire is manufactured to internationally recognized standards and supplied in the sizes most frequently ordered by Indonesian importers and distributors:
| Item | Specification |
|---|---|
| Base material | Wire rod SAE1006, SAE1008, Q195-Q235 |
| Standards | ASTM A641, A853, JIS G3532, GB/T 343 |
| Diameter | 0.5 mm - 6.0 mm |
| Finishes | Galvanized (hot-dip or electro), black annealed, bright |
| Tensile strength | 300 - 1400 MPa per grade and diameter |
| Forms | Spools, coils, cut lengths, straightened wire |
| Packing | Plastic-wrapped coils, palletized spools |
| Certification | ISO 9001:2015, MTC per EN 10204 3.1 |
Tensile Consistency and Zinc Adhesion
Wire performance depends on tensile strength consistency and coating adhesion. We control drawing speed, die profile and annealing cycles so that each coil delivers uniform tensile properties, and galvanized wire is tested for coating weight and adhesion (wrap test) so it survives bending and tying without flaking. Black annealed wire is supplied soft and clean for easy handling on construction sites.
Applications of Steel Wire in Indonesia

Shipping and Logistics to Indonesian Ports
We ship on a monthly rolling schedule to the main Indonesian ports: Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), Belawan (Medan) and Makassar, with regular consolidation for mixed-product container orders. Sea freight from Tianjin to Indonesian ports typically takes 18-25 days. Mixed sizes and mixed product lines can be consolidated in one container to reduce your total landed cost.
Frequently Asked Questions
What is the minimum order quantity?
MOQ is typically 5 metric tons per specification, and mixed-size container loads of 20 or 40 feet are welcomed for distributors and project stock orders.
What are the payment terms?
We accept T/T, L/C, D/A, D/P and O/A for long-term partners. Standard terms are 30% deposit and 70% against copy of shipping documents.
Do you provide Mill Test Certificates?
Yes, every batch ships with an MTC per EN 10204 3.1 including chemical composition and mechanical test results.
How long does delivery to Indonesia take?
Production takes 15-25 days after specification confirmation, followed by 18-25 days sea freight to Tanjung Priok, Tanjung Perak, Belawan or Makassar.
Can third-party inspection be arranged?
Yes, SGS, BV or TUV inspection can be arranged at the factory before loading or at the destination port, which is common for government and project supply in Indonesia.
What is the difference between binding wire and annealed wire?
Binding wire is soft annealed wire used for tying rebar; annealed wire refers to wire softened by heat treatment for general forming and tying use.
Can you supply wire on spools?
Yes, we supply on spools, coils or cut lengths according to your application.
