10 gauge vs. 13 gauge wire

10 gauge and 13 gauge baling wire have different diameters, load strengths, tensile strengths, and use cases. We’ll discuss why wire gauge is important, and the ways these two gauges differ from one another.

Wire diameter vs. wire gauge

A wire’s diameter is inversely related to its gauge. Diameter decreases as gauge increases, and vice versa.

Wire diameter refers to a given wire’s cross-sectional thickness. It is typically expressed in millimeters or inches, and provides a direct measurement of the wire’s physical size.

The diameter of a given gauge of wire may vary depending on the material and manufacturing specifications. For example, 13 gauge galvanized wire in the AWG system will have a specific diameter, but the diameter may differ between copper, steel, or aluminum wires due to variations in their physical properties.

Wire gauge comes from the wire manufacturing process, which involves drawing the wire through progressively smaller holes. The drawing process uses a draw plate, which is a tool with a series of conical or cylindrical holes that decrease in size.

Each pass through a hole reduces the diameter by a specific increment, and subsequently adjusts the wire’s gauge. For example, a 10 gauge wire has been drawn through 10 progressively smaller holes. This process is repeated until the desired diameter is achieved.

North America primarily uses the American Wire Gauge (AWG) system, while the British Standard Wire Gauge (SWG) system is most commonly used in the United Kingdom and some other countries.

Thickness and strength

If all factors are equal, a larger diameter wire will be stronger than a smaller diameter wire (e.g. a 10 gauge wire is stronger than a 13 gauge wire).

A10 gauge wire is 0.046 inches thickerthan a comparable 13 gauge wire. 10 gauge wire is used for baling denser and more expansive materials, due to its greater load and tensile strength.

Baling wire finishes

The process of annealing improves our black annealed wire’s ductility, and the hot-dip galvanizing process adds a rust-resistant layer of zinc to our galvanized products.

Galvanized baling wire is coated in zinc during galvanization, which makes it more resistant to rust, even in wet and humid conditions. The zinc coating acts as a barrier between the steel wire and moisture in the environment, providing corrosion protection.

Annealing involves heating the steel above its recrystallization temperature, maintaining that temperature, and then cooling it. This creates a uniform atomic structure, increases ductility and flexibility, and reduces brittleness to produce a smooth wire that is durable and easy to use.


At Baling Wire Direct, we proudly offer Class 3 galvanization on all of our galvanized wire products, which delivers significantly higher corrosion resistance than standard Class 1 galvanization. Some of the differences between Class 1 and Class 3 galvanization include:

  • Class 1 galvanization. Our Class 1 galvanized steel wire offers a basic zinc coating that uses 0.28 ounces of zinc per square foot. Class 1 galvanized wire is more cost-effective, but will typically rust after anywhere from 2–11 years, depending on the environment. In coastal areas, Class 1 coating fails even sooner due to saltwater corrosion.

Class 3 galvanization. With 0.80 ounces of zinc per square foot, this premium galvanization is nearly 3 times thicker than Class 1. The robust coating is more resistant to corrosion, providing a lifespan of 13–30 years. Class 3 galvanization is better suited for harsh environments.
