Premium Double Loop Wire Ties in All Materials and Specifications
Our industrial-grade Double Loop Wire Ties are engineered to streamline rapid binding, fastening, and sealing workflows across diverse industrial infrastructure and commercial retail settings. Known across global hardware distribution channels as Double Loop Bag Ties or Bar Wire Ties, these high-utility fasteners feature precision-formed circular loops at each end. When paired with manual or semi-automatic loop twisting hook tools, operators can secure bags, reinforcing steel meshes, or agricultural vines with a simple pull-and-twist motion, significantly increasing efficiency compared to traditional straight wire cutting and knotting techniques.
As a leading dedicated wire drawing facility, we take pride in offering the industry’s most versatile multi-material manufacturing spectrum. Every environmental setting requires distinct physical characteristics—whether it is the raw flexibility needed for concrete rebar fixing, the weatherproofing required for vineyard training, or the spark-resistant properties mandatory in petro-chemical packaging lines. Our advanced computer-controlled annealing furnaces guarantee a uniform low-tensile matrix across all materials, ensuring effortless wrapping without material fracture or tool slippage.
Comprehensive Material Selection & Key Technical Selling Points
1. Black Annealed Double Loop Wires (Ultimate Economy)
Manufactured using low-carbon steel rods subjected to oxygen-free thermal softening curves. Coated with clean clear light oil to preserve deep black luster and maximize anti-rust shelf-life, these are the default choice for global concrete reinforcement rebar tying.
2. Galvanized Double Loop Wires (Excellent Rust Resistance)
Available in both Electro-galvanized or heavy Hot-dipped galvanized variations. The zinc structural skin shields the low-carbon steel matrix from active oxidation, making it highly effective for outdoor marine packaging, agricultural mesh support, and harsh environment industrial sorting zones.
3. PVC / PE Coated Double Loop Wires (Color-Coded Protection)
Featuring a thick, heavily adhered PVC insulation outer skin (popular colors include Forest Green, Industrial Black, Yellow, and Deep Blue). The polymer shield protects against aggressive moisture and friction, widely utilized for commercial nursery plant binding, garbage bag sealing, and color-coded inventory sorting.
4. Stainless Steel Wires (Grade 304 / 316 for Extreme Acids)
Engineered explicitly for nuclear, chemical processing plants, coastal structural masonry, and food processing enclosures. Resistant to heavy chemical washdowns, severe salinity, and prolonged high temperatures without degradation.
5. Pure Copper Double Loop Wires (Spark-Proof & Heavy Crafting)
Utilizing high-purity copper core wirings, these ties deliver specialized spark-resistant and static-proof properties. Ideal for securing explosives packaging in mining operations, chemical tank valve tag seals, and high-end aesthetic landscaping/artisan crafting.

Versatile Commercial and Agricultural Applications
Thanks to our comprehensive multi-material production adaptability, these double loop wires cross over multiple crucial business markets seamlessly:
-
-
- Concrete Reinforcement Construction (Bar Ties): Utilizing high-ductility 16G & 17G black annealed variants to securely lace intersecting rebar cages, ensuring tight, non-slip wire meshes before masonry pouring.
- Industrial Heavy Sack and Bag Sealing: Ideal for fast closing heavy polypropylene woven bags, large burlap sacks, and multi-wall paper packages filled with cement, chemical powders, charcoal, or agricultural feeds.
- Nursery, Horticulture, and Greenhouses: Our green PVC coated wire blends into flora environments, gently binding tree trunks to support stakes and routing fruit vines onto overhead trellis frameworks.
- Marine and Highly Corrosive Environment tagging: Using Stainless Steel 316 wire loops to attach metal identification and instruction tags permanently to subsea components, offshore rigs, and chemical tubes.
Frequently Asked Questions (FAQ)
Q1: How do I select the most appropriate material for our specific commercial environment?
A: For common standard structural masonry or indoor packing where wire ties are fully enclosed or quickly consumer used, choose Black Annealed for maximum economy. For high humidity and outdoor packaging, Galvanized or PVC coated wires are necessary. If the ties come into contact with chemical solvents, sea spray, or processed foodstuffs, Grade 304 or 316 Stainless Steel is mandatory to avoid structural cross-contamination.
Q2: Can these wire ties be used with standard automatic twisting hooks available on the open market?
A: Yes, absolutely. Our loop loops are formed using heavy mechanical steel mandrels, ensuring an identical internal circular dimension across every production lot. They are 100% compatible with all global universal hand-pull twisters, electric rebar tier tie hooks, and crank-operated industrial bag sealers.
Q3: Does the PVC coated variant crack or peel away during freezing or high outdoor UV sun exposure?
A: Not at all. Our factory utilizes high-grade, virgin virgin PVC pellets infused with specialized UV-stabilizer chemical agents and cold-temperature plasticizers. This technical formulation ensures that the colorful outer layer remains completely bonded to the internal steel wire core without peeling or cracking, even in cold winter climates down to -20°C or intense hot summer field exposures.
Q4: What is the factory MOQ policy, and can we mix different materials like Galvanized and Black Annealed in one container?
A: Our standard individual material manufacturing MOQ is 5 Metric Tons. However, we highly encourage comprehensive B2B distributors to configure a mixed freight cargo. You can combine multiple length SKUs and distinct materials (e.g., ordering 15 tons of Black Annealed bar ties alongside 5 tons of Green PVC bag ties) to complete one single 20ft container load to serve distinct retail client levels.
