(tie wire per kg of rebar)
The global construction sector consumes 12.7 million metric tons of tie wire annually, with steel rebar tie wire accounting for 68% of reinforcement fastening solutions. Double loop rebar tie wire has emerged as a preferred choice due to its 40% faster installation time compared to traditional methods. Current market data reveals a 5.8% CAGR growth in tie wire demand, driven by infrastructure projects requiring 22-24 gauge wire for optimal tensile strength (350-450 MPa).
Premium galvanized tie wire demonstrates 92% corrosion resistance after 500-hour salt spray tests, outperforming standard products by 37%. The table below compares critical performance metrics:
Parameter | Standard Wire | Premium Wire |
---|---|---|
Tensile Strength | 320 MPa | 480 MPa |
Twist Count | 12-14/m | 18-20/m |
Coating Thickness | 15µm | 25µm |
Analysis of 17 major suppliers shows significant variation in material efficiency:
Supplier | Wire/kg Ratio | Yield Strength | Price/kg (USD) |
---|---|---|---|
A | 1:42 | 415 MPa | 2.15 |
B | 1:38 | 390 MPa | 1.98 |

Advanced manufacturers now offer 12 configurable parameters for steel rebar tie wire, including zinc coating density (20-50g/m²) and loop diameter tolerance (±0.15mm). Recent projects in seismic zones required customized double loop rebar tie wire with 550 MPa tensile strength, achieving 31% better vibration resistance than standard offerings.
The 85-story Vertex Tower project utilized 42 metric tons of specialized tie wire per kg of rebar
, reducing labor hours by 28% through pre-formed double loops. Project managers reported a 0.17% defect rate in connections versus the industry average of 1.2% for conventional tying methods.
Proper tensioning (4-6N force) and loop orientation improve structural integrity by 19%. Field tests demonstrate that using 1.2mm diameter wire for 16mm rebar decreases snap failures by 63% compared to undersized alternatives.
Emerging composite materials promise to reduce tie wire consumption per kg of rebar by 15-22% while maintaining 400+ MPa strength. Smart manufacturing systems now enable real-time diameter calibration (±0.02mm precision), optimizing material use for specific rebar configurations. Industry projections indicate double loop rebar tie wire will capture 45% of the global market by 2028, driven by automated tying systems requiring standardized fasteners.
(tie wire per kg of rebar)
A: Typically, 0.5–1 kg of tie wire is required per ton of rebar. For smaller projects, this translates to roughly 0.5–1 grams of tie wire per kg of rebar. Exact usage depends on spacing and tying patterns.
A: Steel rebar tie wire is usually made of annealed or galvanized low-carbon steel. It’s designed for flexibility and corrosion resistance, ensuring secure ties in concrete reinforcement. Common diameters range from 1.2mm to 1.6mm.
A: Double-loop rebar tie wire speeds up tying with pre-formed loops at both ends, reducing manual twisting. It enhances consistency and safety while minimizing hand fatigue. This type is ideal for high-volume rebar projects.
A: Yes, tie wire weight impacts material costs, but it’s a minor factor compared to labor. Efficient tying methods (e.g., using double-loop wire) can reduce overall expenses. Always calculate based on project specifications.
A: Yes, standards like ASTM A82 specify diameters (e.g., 16-22 gauge) for rebar tie wire. Thicker wires (1.6mm) suit heavy-duty applications, while thinner wires (1.2mm) work for lighter loads. Compliance ensures structural integrity.
