How to choose the correct wire for my vertical baler

Many types of baling wire work with vertical balers. Weigh the following three factors when making your choice for a safe and efficient recycling operation:

  1. Baler requirements
  2. Material requirements
  3. Storage requirements

Baler requirements

To choose the right wire for your machine, determine whether it is a manual-tie or auto-tie vertical baler.

Most vertical balers are manual, which require bale ties (also known as wire ties or baler ties). The baler operator manually fastens these wires. You can order single loop and double loop configurations, depending on your baling equipment and material requirements.

Auto-tie vertical balers use stem wire or box wire. They automatically cut and tie the wire to secure the bales. While less common, some vertical balers are automatic. Our 11 gauge black annealed wire is a great multi-purpose automatic wire (auto-tie wire).

Some balers work best with specific wire gauges. Read your baling machine manual, or consult your baling machine manufacturer to choose the best wire gauge for your vertical baler. Check out our baling wire gauge guide to learn more.

Material requirements

Each type of material requires a wire with a different tensile strength to secure the bale. Lighter materials, such as foam and paper products, can be baled with higher gauge wire (smaller wire diameter). Heavier bales often demand high-tensile baling wire.

For automatic vertical balers, our 11 gauge hi-tensile galvanized wire is the strongest choice. For manual-tie vertical balers, our 9 gauge galvanized double loop bale ties offer an impressive tensile strength of 220,000 psi.

Storage requirements

Determine the conditions in which your bales will be stored, as well as for how long. If you are shipping your bales after processing, consult the recycling facility to see if they have any specific wire requirements or recommendations.

Regular, untreated bale wire will rust if exposed to corrosive, humid, or wet conditions. Even annealed wire will rust since its waxy coating isn’t specifically designed for long-term protection. Bales that will be stored outside for extended periods should be baled with galvanized wire.

The galvanizing process produces baling wire with a protective zinc layer, specifically engineered to combat rust and corrosion. A wire’s galvanization class determines how thick its zinc coat is. While we offer Class 1 and Class 3 galvanization, Class 3 galvanization provides significantly enhanced protection against the elements, making it the best choice for bales that will be stored outdoors.

Product recommendations for vertical balers

Here are some of our most popular types of wire for vertical balers.

Single loop bale ties

Single loop bale ties feature a loop at one end and a working end for tying, great for adjusting the tightness of the bale or tying inconsistent bale sizes. Our 11 gauge annealed single loop bale ties are a good choice for manual vertical balers. Single loop configurations are easy to use, and annealed wire offers enhanced elongation and torsional strength for baling expansive materials, such as tires.

Double loop bale ties

Double loop bale ties feature a loop at both ends. The loops join together for rapid tying. Our 10 gauge bright double loop bale ties make manual tying a breeze. Double loop configurations are pre-cut to specific sizes. They work best with recyclables such as office paper, which produce uniformly sized bales. Unfinished (bright) baling wire is also cheaper than other wire finishes, offering an economical solution for applications that don’t require corrosion resistance.
