11 gauge vs. 13 gauge wire

11 gauge and 13 gauge baling wires are different in thickness, load strength, and tensile strength. We’ll talk about the importance of wire gauge and the differences between 11 and 13 gauge wire.

Wire gauge vs. wire diameter

Wire gauge is inversely correlated to wire diameter. The smaller the diameter, the larger the gauge, and vice versa.

Wire gauge is derived 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.

As the wire passes through each hole, its diameter is reduced by a specific increment. This process is repeated until the desired diameter is achieved.

The dominant gauge system in North America is the American Wire Gauge (AWG) system, while the UK and some other countries more commonly use British Standard Wire Gauge (SWG).

Wire diameter refers to a given wire’s cross sectional thickness. It is typically expressed in millimeters or inches, and it 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. An 11 gauge black annealed box wire in the AWG system, for example, will have a specific diameter, but the diameter may differ between copper, steel, or aluminum wires due to variations in their physical properties.

Thickness and strength

If all factors are the same, a thicker wire will be stronger than a thinner wire (e.g. an 11 gauge wire is stronger than a 13 gauge wire).

0.088–0.090 inches

Tensile strength

65,000–220,000 psi depending on wire type

50,000–95,000 psi depending on wire type

Recycling: baling cardboard, plastic, aluminum, tissue paper.

Recycling: baling cardboard, plastic, aluminum, tissue paper. Preferred for lighter, lower-density bales.

An 11 gauge wire is 0.029 inches thicker than a 13 gauge wire, and has greater tensile strength and load strength. 11 gauge wire is used to bale heavier, more dense materials.

Baling wire finishes

The process of annealing improves the ductility and elongation of our black annealed wire, and the hot-dip galvanizing process coats our galvanized wire products in a protective zinc layer.

The zinc coating of galvanized baling wire makes it more resistant to corrosion, 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 elongation and ductility, and reduces hardness to produce a smooth wire that is durable and easy to work with.

At Baling Wire Direct, we proudly offer Class 3 galvanization on all available gauges, delivering significantly higher corrosion resistance than standard Class 1 galvanization. Here are some of the distinctions between galvanization classes:

  • 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 the ideal choice for extreme environmental conditions.
