Our quality commitment

Baling Wire Direct is one of the largest baling wire manufacturing companies in North America. Our baler wire is created to surpass the highest standards of quality.

We carry out rigorous testing on all of our products to ensure they perform to the highest industry standards. The wire that fails to meet our quality assurance criteria is removed from stock, guaranteeing only strong and reliable carrier wire reaches our customers.

We control every aspect of production and distribution, which allows us to deliver premium products at the lowest prices, with unparalleled customer service.

Our Autoship™ system keeps you informed every step of the way, ensuring the smoothest possible purchasing experience. Receive live tracking information via email or text message, and enjoy quick delivery in as little as 1–3 business days!

Galvanization classes

Baling Wire Direct offers Class 1 and Class 3 galvanization on our galvanized wire products. Class 1 is more cost-effective, but degrades faster than Class 3 galvanization. Class 3 creates a thicker zinc coating to improve performance and longevity:

• Class 1 galvanization is the most basic type of coating, typically used for fencing, caging, and enclosures. The wire is galvanized by adding a thin, protective layer of zinc. It is the cheaper and more cost-efficient option, but it is not as effective long term. Class 1 galvanized wire will last a maximum of 11 years and in some cases as little as 2. In coastal areas with salty air, the protective layer tends to deteriorate even quicker. 
• Class 3 galvanization provides a thicker, longer-lasting zinc coating. Whereas Class 1 uses 0.28 ounces of zinc per square foot, Class 3 galvanized wire has a zinc coating that is nearly three times thicker (approximately 0.80 ounces per square foot). It costs slightly more than Class 1, but will last anywhere from 13–30 years before it rusts, making it well worth the investment.

Our galvanization process

Our galvanization process follows these 7 steps:

1. Surface preparation: first, the wire is cleaned to remove any surface impurities. This ensures proper adhesion of the zinc coating.
2. Pickling: the wire is immersed in an acid solution to remove any remaining oxides and scale. This process prepares the surface for galvanizing by creating a clean substrate.
3. Fluxing: the wire is then immersed in a flux solution (zinc ammonium chloride), which prevents oxidation and promotes a uniform application of the zinc coating.
4. Galvanizing bath: next, the wire is dipped into a 450°C (850°F) bath of molten zinc.
5. Alloy formation: while immersed in the molten zinc, a metallurgical reaction occurs between the iron in the wire and the zinc, resulting in the formation of a series of zinc-iron alloy layers. These provide excellent abrasion and corrosion resistance.
6. Withdrawal: the wire is gradually withdrawn from the zinc bath. The rate at which the withdrawal takes place is controlled to allow excess zinc to drain off and ensure the final product has an even coating.
7. Quenching: the coated wire is then quenched in water or a quenching solution to cool it rapidly. This process solidifies the zinc coating and completes the galvanizing process.

After galvanization, a wax coat is applied to the galvanized wire. This creates a clean surface finish and also provides additional protection. The smooth wire finish prevents scrap metal messes and always feeds properly into automatic baling machines.

Galvanized finish versus bright finish

We sell double loop wire ties in two finishes: galvanized and bright. While both are used to bundle materials together, their coating gives them different advantages.

Galvanized wire ties are better when:

• Bales will be exposed to weather
• Corrosive material is being baled

Bright finished ties, or raw steel ties, have no additional coating added to them. They are best when:

• Budget is a priority
• The bales might expand (bright bale ties have more elasticity than galvanized ties)
• Bales are client-facing, requiring a slightly nicer appearance.

The choice between galvanized and bright bale ties depends on the specific requirements of the baling operation, including the type of material being baled, the environmental conditions, and the need for corrosion resistance. If a bright finish makes sense, consider our 12.5 gauge bright double loop bale ties.
