Key Features of Galvanized stitching wire
- Strong anti-corrosion performance: Due to the galvanized layer on the surface, it can resist erosion in various environments and extend its service life. No fear of outdoor or humid environments.
- High strength: Galvanized steel wire inherits the characteristics of high strength of steel wire and can withstand greater tension and pressure. Therefore, galvanized staple wire can still maintain a high tensile strength.
- Good wear resistance: The galvanized layer can increase the hardness of the steel wire surface, make the surface of the iron wire smoother, improve its wear resistance, and reduce friction loss.
- Easy to process: It also has good plasticity and processability, and can be easily bent, cut and welded to meet the needs of various processing.
- Aesthetics: The galvanized layer gives the iron wire a silvery-white appearance, making it more beautiful in applications that need to be exposed to the outside.
Physical properties
Physical properties | Typical values/description |
Tensile Strength | 300–1200 MPa (adjusted by material and application, such as low carbon steel or high carbon steel) |
Elongation | 5%–20% (related to carbon content and coating process, low carbon steel has higher ductility) |
Zinc Coating | 10–60 g/m² (conventional galvanizing) or higher (such as thick coating for corrosion protection) |
Diameter Tolerance | ±0.02 mm (precision application) to ±0.05 mm (general application) |
Hardness | 120–300 HV (Vickers hardness, depending on cold working and annealing process) |
Bendability | Can be wound/bent 180° without cracks (low carbon steel is better, high carbon steel needs annealing) |
Corrosion Resistance | Salt spray test (neutral) ≥48–500 hours (the thicker the zinc layer, the stronger the corrosion protection) |

Common wire gauges and sizes
Common specifications include diameter, length, packaging, etc. For example, some galvanized sutures have a diameter of 0.9X0.55mm, while others express the diameter and length per kilogram according to the German Wire Gauge (GWG), American Wire Gauge (ASWG) or British Wire Gauge (BWG). The following is its wire gauge and diameter for your reference.

Examples of wire gauges used in staplers
The majority of the stitching wire used in today’s binderies and in-line stitching operations is 24 and 25 gauge. The difference in size from 24 Gauge (.023”) to 25 gauge (.0204”) is .0026”.
A 24 Gauge wire has 8,496 inches per pound of wire and 25 Gauge has 10,800 inches per pound. This amounts to a 21.3% difference in product yield, which translates into 21.3% more staples if you use 25 Gauge over 24 Gauge. In simpler terms if you imagine a staple or stitch being 1 inch, you would have 2,304 more staples by using the 25 Gauge wire over 24 Gauge.
Recommended wire gauge
- 25 gauge stitching wire’s recommended thickness of work is 1/16 to 7/32 of an inch.
- 24 gauge stitching wire’s recommended thickness of work is 1/16 – ¼ of an inch.
These are only suggestions as paper type, density, coatings, and stitcher setup can change the stitching wire size required.
What are the applications of Galvanized stitching wire?
- Packaging industry: fix the edges of cartons and packaging boxes, bundle goods in logistics and warehousing to prevent goods from scattering or damage.
- Building and construction: can be used to fix building templates, and to connect and fix structures such as fences and protective nets.
- Furniture manufacturing: used to fix furniture components such as drawer slides, door panels, etc. Fix the fillings of soft furniture such as sofas and mattresses.
- Agriculture and gardening: fix plant stems, provide support, and prevent lodging. Used to build farmland fences, livestock fences, etc.
- Handicrafts and DIY: Because it is easy to bend and fix, it is often used in the production of handicrafts, such as weaving, beading, etc. It can be used to fix, connect or decorate various DIY materials.
- Automobile manufacturing: galvanized staplers can be used to fix interior parts, wiring harnesses and other components.
- Electronic product manufacturing: fix circuit boards, components, etc. to ensure product stability and reliability
