Binding Wire

Description

1. Product Overview

Binding Wire is a high-tensile, low-carbon annealed steel wire engineered for secure fastening and reinforcement in construction, infrastructure, and industrial packaging. Its primary industrial use is tying rebar in concrete reinforcement, securing formwork, and bundling heavy-duty materials for transport. The key value proposition is exceptional malleability combined with consistent tensile strength, ensuring rapid, fatigue-resistant binding that reduces labor time and material waste. Strategically, it is a critical consumable in global construction and logistics—where supply chain reliability and mechanical conformity directly impact project margins and safety compliance.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Low-carbon steel (C: 0.06–0.12%, Mn: 0.30–0.50%, P ≤ 0.035%, S ≤ 0.035%)

• Processing: Annealed (black or bright) / Galvanized (electro or hot-dip) upon request

• Tensile Strength: 350–550 N/mm² (annealed); 600–850 N/mm² (as-drawn)

• Wire Diameter: 0.5 mm to 4.0 mm (±0.02 mm tolerance)

• Elongation: ≥ 18% (ensures bending without fracture)

• Surface Finish: Oxidized black (natural annealed) or bright zinc-coated (5–15 µm)

• Packaging Options: Coils (0.5–100 kg), spools, PP-wrapped rolls, or wooden reels; anti-rust VCI paper on request

• Shelf Life: 12 months (uncoated, dry storage); 24 months (galvanized, under cover)

3. Core Industrial Applications

• Construction & Infrastructure: Tying rebar in bridges, high-rises, dams, and road foundations. Outperforms standard wire due to uniform softness after annealing—reduces hand fatigue and tool wear by 20–30%.

• Industrial Packaging & Baling: Bundling steel bars, pipes, timber, or scrap metal. Higher ductility prevents spring-back, securing irregular loads tighter than poly strapping or hardened wire.

• Agriculture & Fencing: Fastening trellises, mesh fencing, and greenhouse structures. Resistance to cyclic loading (wind/weight) exceeds PVC-coated alternatives in cost-per-cycle analysis.

• Prefabricated Rebar Cages: Enables automated tying machines with consistent wire feed, lowering rejects by 15% compared to non-spec wire.

4. Competitive Advantages

• Quality Consistency: ISO 9001:2025 certified mill control; every batch tested for tensile, elongation, and diameter via laser micrometry.

• Supply Reliability: Dual-sourced raw steel with 99.2% on-time dispatch rate over 36 months; buffer stock maintained in three regional hubs (Asia, MENA, LATAM).

• Logistics Capability: Direct container loading from mill to port; lead time 14–21 days FOB any major origin port.

• Price Competitiveness: Tier-1 Chinese, Indian, and Turkish production routes offering 12–18% landed cost advantage over European mills without compromising ASTM A82 / BS 4482 standards.

• Technical Support: Full mill test certificates (MTC) per EN 10204 3.1; weldability and bending protocols available. Third-party inspection (SGS/BV) optional at cost.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20MT per specification (diameter + coating)

• Loading Capacity (per 20’ GP container): 22–24 MT (depending on coil size and packaging)

• Loading Capacity (per 40’ HC container): 25–26 MT (optimized stacking)
