21 Gauge Tie Wire Coils for Rebar Tying Machine are high-precision rebar tying wire spools designed for automatic rebar tying machines used in foundations, bridges, retaining walls, precast concrete, floors, walls, swimming pools, radiant heating tubes and electrical conduit fastening. Each coil uses 0.8mm / 21 gauge wire with 100m wire length and 0.4kg net weight per reel, helping contractors achieve fast and stable rebar tying performance.
KYA 21 gauge rebar tie wire is available in galvanized wire, black annealed wire, 304 stainless steel wire and plastic coated wire options. It is designed for automatic rebar tiers such as KYA-460, similar rebar tying tools and compatible models such as MAX RB441T, where 0.8mm tie wire coils are required.
21 gauge rebar tie wire coils are engineered for smooth feeding, consistent knot formation and efficient automatic tying. The soft round wire section, controlled tensile strength and easy-to-load spool design help reduce wire breakage, tool jams and downtime during concrete reinforcement work.
0.8mm / 21 gauge wire: Designed for compatible automatic rebar tying machines.
100m wire length per coil: Provides long working time between spool changes.
0.4kg per reel: Lightweight spool for fast loading and efficient field operation.
50 coils per carton: Suitable for contractors, distributors and construction material suppliers.
350–400 MPA wire tensile strength: Balances strength and flexibility for automatic tying.
Multiple surface treatments: Black annealed, electro-galvanized and plastic coated options support different construction environments.

| Surface Treatment | Description | Recommended Use |
|---|---|---|
| Black Annealed | Low carbon steel, dead soft annealed wire with black oxide finish. | General construction, precast concrete and pre-stressed concrete applications where mild corrosion resistance is acceptable. |
| Electro-Galvanized | Low carbon steel, dead soft annealed wire with approximately 5-micron zinc coating. | Precast or pre-stressed concrete applications requiring greater corrosion resistance, including marine or harsh environments. |
| Plastic Coated | Low carbon steel, dead soft annealed wire powder-coated with a 0.05mm yellow polyester layer. | Epoxy-coated rebar, DOT-mandated applications and projects requiring added protection against corrosion and abrasives. |
| 304 Stainless Steel | Stainless steel tie wire option with higher corrosion resistance. | High-humidity, outdoor or corrosion-sensitive construction applications where stainless wire is specified. |
21 Gauge Tie Wire Coils are used with automatic rebar tying machines to secure rebar intersections in reinforced concrete projects. The wire is suitable for high-volume tying where consistent feeding, knot strength and construction efficiency are important.

| Tying Yield | Approximately 120–190 knots per reel depending on wire length per knot | Estimate coil consumption based on rebar size, tie setting and project quantity. |
| Carton Packing | 50 coils per carton | Suitable for jobsite supply, distributor inventory and construction project procurement. |
It is used with automatic rebar tying machines to secure rebar in reinforced concrete construction, including foundations, bridges, retaining walls, floors, walls, swimming pools and precast concrete products.
These 0.8mm tie wire coils are compatible with most automatic rebar tying machines that use 21 gauge wire, including KYA-460 and similar machine types such as MAX RB441T. Always confirm tool wire size and spool compatibility before ordering.
One coil can make approximately 120–190 knots per reel, depending on the machine setting, tie diameter and wire length used for each knot.
Yes. Electro-galvanized, stainless steel and plastic coated options provide different levels of corrosion resistance. For harsh outdoor, marine or DOT-specified projects, choose the finish required by the project specification.
Black annealed wire is soft low carbon steel wire with a black oxide finish for general construction use. Electro-galvanized wire adds a zinc coating for improved corrosion resistance in harsher environments.
Plastic coated tie wire is commonly selected for epoxy-coated rebar or DOT-mandated applications where added protection against corrosion and abrasive contact is required.
