(rebar tie wire)
Rebar tie wire remains indispensable in modern construction for securing steel reinforcement matrices. Industry reports indicate 92% of concrete structures utilize galvanized or coated tie wires, with global consumption reaching 4.7 million metric tons annually. The material's critical role in maintaining structural integrity during concrete pouring necessitates rigorous quality standards.
Advanced metallurgical treatments enhance corrosion resistance:
Field studies demonstrate properly coated tie wires maintain 97% structural integrity after 25 years in coastal environments.
Standard consumption ratios for various rebar configurations:
Rebar Diameter (mm) | Tie Wire per Ton (kg) | Joint Type |
---|---|---|
10 | 8.2 | Cross |
16 | 6.7 | Saddle |
25 | 5.1 | Wrap |
Automated tying machines reduce wire usage by 18-22% compared to manual methods.
High-carbon tie wires (0.70-0.80% C content) achieve tensile strength of 1,400-1,600 MPa, outperforming standard annealed wires by 63%. The enhanced ductility (minimum 12% elongation) prevents brittle fracture during seismic events.
Vendor | Wire Gauge | Tensile (MPa) | Price/Ton |
---|---|---|---|
SteelCo | 16 AWG | 1,550 | $1,200 |
Metallix | 18 AWG | 1,480 | $1,350 |
FortisWire | 17 AWG | 1,620 | $1,410 |
Third-party testing reveals 23% variance in actual vs claimed specifications across sampled products.
Customization parameters for specialized applications:
Prefabrication bundles reduce onsite labor hours by 35% in high-rise projects.
The Øresund Bridge project consumed 82 metric tons of 316L stainless tie wire, demonstrating exceptional performance in marine conditions. Accelerated aging tests confirm coated systems maintain 94% of initial clamping force after equivalent 30-year exposure, validating long-term reliability for critical infrastructure.
(rebar tie wire)
A: Yes, standard rebar tie wire made of untreated steel can rust when exposed to moisture or harsh environmental conditions. Using galvanized or coated tie wire significantly reduces rust risk.
A: Approximately 0.5–1 kg of tie wire is required per ton (1,000 kg) of rebar, depending on rebar spacing and tie density. This translates to roughly 0.0005–0.001 kg of tie wire per kg of rebar.
A: Rebar tie wire is typically made from annealed steel, which is flexible and durable. Galvanized or epoxy-coated variants are also available for corrosion resistance in aggressive environments.
A: Reuse is not recommended, as tie wire loses tension and integrity after initial application. Damaged or rusted wire should always be replaced to ensure structural stability.
A: Plastic zip ties or composite straps are alternatives, but they are less common due to lower strength and heat sensitivity. Steel tie wire remains standard for securing rebar in construction.
