Technical Specifications

State-of-the-art Production Technology from Vietnam

Efreso’s industrial steel wires are processed at elite vietnam steel mills operating high-speed drawing machines and continuous annealing furnaces engineered by global metallurgical pioneers like Danieli (Italy) and SMS Group (Germany). Our inline mechanical descaling, precise chemical pickling, and multi-stage cold drawing processes ensure consistent mechanical properties, exceptional roundness, and zero surface decarburization. This high-precision manufacturing eliminates wire breakage risks during high-speed downstream processing.

As a leading vietnam steel exporter, we actively champion eco-conscious industrial practices. Our partner drawing mills utilize closed-loop acid regeneration plants, zero-discharge water treatment systems, and energy-circulated heat recovery systems, making our wire products central to the green steel vietnam transition. This rigorous carbon and environmental tracking ensures our entire wire portfolio is fully CBAM ready, providing European, North American, and Australian buyers with seamless carbon-accounting compliance.

Why Choose Efreso's Industrial Steel Wires?

• Uniform Tensile & Elongation: Advanced inline heat treatment guarantees consistent mechanical properties from the inner core to the outer wrap of every coil, preventing unexpected snags or breaks during high-speed spring coiling or mesh weaving.

• Superior Surface Adhesion: Our state-of-the-art phosphate and zinc-coating lines create an incredibly tight metallurgical bond, providing exceptional lubrication carrier properties for further drawing or long-lasting corrosion resistance.

• Strict Dimensional Accuracy: Utilizing laser-micrometer diameter control, our wires maintain ultra-tight diameter tolerances, minimizing wear on your forming dies and machinery.

• Excellent Formability: Optimized grain structures yield superb bending, twisting, and cold-heading capabilities, perfect for complex wire-forming applications.

Strategic Sourcing Advantages from Vietnam

• Tariff & Duty Savings (Up to 0% Preferential Tariffs): Take full advantage of Vietnam's integration into global trade. Our industrial steel wires qualify for up to 0% import tariffs in key destination markets under active agreements such as the EVFTA (Europe), CPTPP (Americas/Pacific), UKVFTA (United Kingdom), and RCEP (Asia-Pacific), fully backed by verified, mill-traceable Certificates of Origin (C/O).

• Anti-Dumping Mitigation: Our wire products are manufactured utilizing 100% Vietnamese local hot-rolled wire rod substrates. This local origin provides a highly secure legal pathway to bypass punitive anti-dumping duties and trade defense measures applied to other regional exporting nations.

• Logistics Efficiency & Deep-Sea Access: Positioned adjacent to major deep-water port systems such as Hai Phong, Da Nang, and Cai Mep - Thi Vai, Efreso guarantees rapid cargo loading, secure vessel container allocations, and optimized ocean freight rates to major industrial ports worldwide.

Key Applications & Industries

• Construction & Infrastructure: Concrete reinforcement mesh, tie wire, gabion boxes, razor wire, high-tensile fencing, and pre-stressed concrete (PC) wire.

• Automotive & Machinery: High-fatigue mechanical springs, seat frames, control cables, fasteners, and Cold Heading Quality (CHQ) bolts and rivets.

• Manufacturing & Consumer Goods: Wire baskets, supermarket trolleys, display racks, clothes hangers, and agricultural binding wires.

• Cable Armoring: Galvanized steel wire wrapping for heavy-duty subsea power cables and telecommunication lines.

Packaging, Loading & Delivery Details

Efreso applies heavy-duty, seaworthy packaging to protect your steel wire coils from moisture, salt spray, and physical deformation during long-haul transit.

• Supply Ability: 30,000 Metric Tons per Month.

• Minimum Order Quantity (MOQ): 25 Metric Tons (1 x 20GP FCL container).

• Export Packaging: Coils are tightly strapped with high-tensile steel bands, wrapped in heavy-duty anti-rust VCI (Vapor Corrosion Inhibitor) film, covered with woven PP fabric, and secured on wooden or steel pallets with lifting eyes.

• Payment Terms: Irrevocable L/C at sight, or flexible T/T (Telegraphic Transfer) with agreed deposit terms.

Frequently Asked Questions

Q1: Do you provide Cold Heading Quality (CHQ) wire for fastener manufacturing?

Yes. We supply specialized low, medium, and alloy CHQ steel wires (such as 10B21, 35K, SCM435) with spheroidized annealing. This ensures an ultra-soft structure, uniform hardness, and excellent cold-forging formability required for manufacturing high-strength bolts, nuts, and screws.

Q2: Can we arrange third-party testing (SGS, Bureau Veritas) for chemical composition and tensile limits?

Absolutely. We actively support pre-shipment inspections (PSI) conducted by international agencies like SGS, Bureau Veritas, or Intertek. We perform tensile tests, wrapping tests, zinc-coating mass checks, and chemical ladle analyses at our labs, providing a full Mill Test Certificate (MTC) conforming to EN 10204 3.1 with every shipment.

Q3: How does Efreso handle shipping documents for FTA duty exemption?

We handle the entire documentation cycle internally. Upon production completion, we submit the necessary raw material traces to the Vietnamese Ministry of Industry and Trade (MoIT) to issue the preferential Certificate of Origin (e.g., Form EUR.1 for European buyers, Form CPTPP, or Form AJ/VJ). Draft documents are always sent to your import broker for verification prior to vessel departure.
