KYA 21 gauge PVC-coated rebar tie wire is supplied for compatible automatic rebar tying machines that use a 0.8mm single-wire spool format. Each reel contains approximately 100m of wire and weighs about 0.4kg.
The standard product specification on this page uses a Q195 galvanized steel wire core with an external PVC coating. The coated surface provides an additional barrier between the steel tie wire and the surrounding environment and is useful in reinforced-concrete applications where a coated tie wire is specified.
Automatic rebar tying machines use tool-specific wire diameters, reel dimensions, hub geometry and feed systems. A 21 gauge or 0.8mm description alone does not establish machine compatibility. Buyers should provide the exact tying-machine model and existing wire-spool reference before ordering replacement reels.

This product combines a soft steel tie wire with a PVC-coated exterior and automatic rebar-tier spool format. The reel is intended to feed continuously through a compatible tying machine, where the wire is advanced, wrapped around the reinforcement, cut and twisted to complete each tie.
The PVC layer separates the galvanized steel core from direct contact with surrounding reinforcement and the jobsite environment. This can be useful where a coated tie wire is specified instead of exposed steel tie wire.
A polymer coating provides a softer external interface than bare steel wire. When used around coated reinforcing bar, this can help reduce direct metal-to-coating contact during automatic tying.
The coating should not be treated as a guarantee against damage to reinforcement coatings. Tool tension, wire feed, tie position and installation technique can all affect the completed tie.
KYA lists this product with a soft temper and round wire section. Automatic tying wire must be flexible enough to feed, curl and twist correctly while retaining sufficient strength for the completed tie.
Each reel contains approximately 100m of tie wire. Actual working output depends on the tying machine and the amount of wire used for each knot.
Coated tie wires are commonly selected when tying epoxy-coated reinforcement because a polymer exterior reduces direct contact between exposed steel tie wire and the epoxy-coated reinforcing bar.
The required tie-wire coating should follow the structural drawings, reinforcement specification, project requirements or applicable purchasing standard. PVC-coated, polyester-coated and other polymer-coated tie wires should not automatically be treated as identical materials.
If the project specifically requires PVC, polyester or another polymer chemistry, state the required coating material when requesting a quotation.
| Wire Type | Typical Use | Selection Note |
|---|---|---|
| Black Annealed | General concrete reinforcement where uncoated tie wire is permitted | Low-carbon soft wire with limited surface corrosion protection |
| Electro-Galvanized | Projects specifying zinc-coated tie wire | Confirm required zinc coating and exposure conditions |
| PVC-Coated | Applications requiring a polymer-coated tie wire | Exact product shown on this page |
| Polyester-Coated | Often specified for epoxy-coated rebar and abrasion-sensitive applications | Different polymer chemistry from PVC; specify separately |
| Stainless Steel | Projects specifically requiring stainless tie wire | Tool and wire specification must support the stainless consumable |
This 0.8mm single-wire reel should only be used in automatic rebar tying machines whose wire diameter, spool dimensions, hub geometry and feeding mechanism match the KYA reel.
Do not assume compatibility with a rebar tier because it is described as an automatic tying machine. Modern twin-wire machines frequently use substantially different wire diameters, spool lengths and reel systems.
| Tool / Wire System | Published Wire Format | KYA 0.8mm PVC Reel |
|---|---|---|
| KYA-460 Twin Tier | 1.0mm / 19GA twin-wire system | Not the published KYA-460 wire specification |
| MAX RB441T TwinTier | TW1061T 19GA twin-wire system; approximately 1.0mm standard or 1.1mm poly-coated wire | Not compatible based on published MAX wire specification |
| MAX TW898 Family Tools | MAX-specific single-wire spool system; current TW898-PC is published as plastic-coated wire | Do not assume interchangeability; verify finished wire diameter and spool geometry |
| Other 21GA Rebar Tiers | Varies by manufacturer and model | Must accept the 0.8mm wire and exact KYA reel dimensions |
| Compatibility Factor | What to Confirm |
|---|---|
| Wire Diameter | Tool must be designed for the nominal and finished coated-wire diameter |
| Single or Twin Wire | A twin-wire tying machine cannot be assumed to accept a conventional single-wire spool |
| Reel Outside Diameter | Reel must fit inside the spool compartment |
| Reel Width | Must align correctly with the feed path |
| Hub Geometry | Center hub must engage the tool's reel holder correctly |
| Wire Stiffness | Wire must feed, curl, cut and twist correctly |
| Coating | Coated outside diameter must pass through guides, feed gears and cutter |
KYA publishes an approximate range of 120–190 ties from one reel. This is not a fixed output for every tying machine or reinforcement combination.
The number of completed ties depends on wire consumption per knot, number of wraps, reinforcement diameter, tie configuration and machine setting. KYA lists approximately 40–50cm of wire consumption for one knot as a reference range.
For project planning, calculate reel consumption using the actual tying tool and the reinforcement combination used on site rather than relying only on the maximum published tie count.
Where a project uses epoxy-coated rebar, stainless reinforcement or another corrosion-control system, follow the engineer's reinforcement and tie-wire specification when selecting the wire material.
The following values are currently published by KYA for this 0.8mm tie-wire product. Buyers requiring certified mechanical-property data should request the applicable production-lot documentation.

KYA Fasteners states that it has more than 20 years of fastener manufacturing experience, serves customers in over 50 countries and supports its quality-control program with SGS certification. Buyers can request the applicable company or product documentation for their project.
KYA lists shipment from Qingdao port within 20–30 days after deposit and offers customized fastener solutions. Confirm the current production schedule, order quantity and custom requirements when requesting a quotation.
The product is specified as 21 gauge with a nominal 0.8mm wire diameter, 100m length and approximately 0.4kg net weight per reel.
KYA currently specifies a Q195 galvanized steel wire core for this product.
The product shown on this page is specified as PVC-coated tie wire. PVC and polyester are different polymer materials and should be specified separately when coating chemistry is important to the project.
Polymer-coated tie wire can be selected where a coated tie is required around epoxy-coated reinforcement. Confirm that PVC coating is permitted by the project's reinforcement specification before use.
KYA publishes approximately 120–190 ties per reel. Actual output depends on the tying machine, rebar combination, number of wraps and amount of wire consumed for each tie.
KYA currently lists 50 reels per carton for this 21 gauge product.
No direct compatibility should be assumed. The current KYA-460 specification uses a 1.0mm / 19 gauge twin-wire system, while this product is a 0.8mm / 21 gauge single-wire reel.
No. MAX specifies the RB441T for its TW1061T twin-wire system. The published wire diameter is approximately 1.0mm for standard TW1061T and 1.1mm for the poly-coated TW1061T-PC, which does not match this 0.8mm single-wire reel.
Do not assume direct interchangeability. MAX identifies the RB397 with the TW898 wire family, while current MAX plastic-coated TW898-PC has its own published wire and reel specification. Compare the complete finished wire diameter and spool geometry before using a replacement reel.
No. Gauge or nominal wire diameter is only one parameter. Reel dimensions, hub geometry, single- or twin-wire format, finished coated diameter, stiffness and feed-system geometry must also match the tying machine.
The PVC coating provides an additional surface barrier, but project suitability depends on exposure conditions, coating integrity, reinforcement system and project requirements. Do not treat the coating as an unconditional guarantee against corrosion.
KYA currently publishes a wire tensile strength of 350–400 MPa and elongation of 23%–27% for this product.
Automatic rebar tie wire is used in foundations, bridges, floors, walls, retaining structures and precast concrete work. The required wire material and coating should follow the reinforcement and project specification.
These are established applications for automatic tying systems where the tube or conduit manufacturer and installation specification permit wire tying. Select the tool, tension setting and wire coating accordingly.
Compare the tying-machine model, original consumable reference, nominal and finished wire diameter, reel outside diameter, reel width, hub dimensions, single- or twin-wire configuration, wire length and coating type.
Provide the required quantity, automatic rebar tier manufacturer and exact model, current wire-spool reference, reinforcement type, required coating and delivery destination. Specify 21 gauge, 0.8mm × 100m PVC-coated tie wire for the product shown on this page.
