Galvanized vs. bright baling wire

Galvanized and bright baling wire each offer distinct advantages. To choose the right type of baling wire for your purpose, match to your baler, the material you’re baling, and duration of time you’ll be storing the bales. Then, consult the following table on galvanized versus bright baling wire.

About bright baling wire

Bright baling wire is uncoated, meaning that the raw steel shows with a “bright” appearance. This type of wire is known for its:

  • Cost-effectiveness: the absence of coatings or treatments during the manufacturing process reduces costs, making bright steel wire an attractive option for indoor or short-term baling applications.
  • Aesthetic appeal: the bright finish gives the wire a clean, attractive look, desired for retail settings and client-facing applications.
  • High tensile strength: bright baling wire offers sufficient tensile strength for baling most recyclables.

Common uses

Recycling facilities use bright baling wire for baling materials that require short-term indoor storage, such as:

Bright baling wire rusts quicker than galvanized wire. It is best for applications where corrosion resistance is unnecessary.

Our manufacturing process

Our bright baling wire undergoes a meticulous manufacturing process to produce superior-quality wire. The process involves:

  1. We purchase premium-grade US steel with the appropriate carbon content and metallurgical traceability documents.
  2. The steel rods undergo a mechanical reverse-bending descaling technique to remove mill scale and surface rust.
  3. A bull-block continuous wire machine draws the steel rods through progressively narrower die gauges until the desired wire diameter is reached.
  4. We apply strict quality control measures so only high-quality baling wire reaches our customers.

About galvanized baling wire

Galvanized steel wire goes through a hot-dip galvanizing process, which involves coating the steel wire with a protective layerof zinc. This zinc coating acts as a sacrificial layer, protecting the underlying steel from rust and corrosion. Galvanized steel wire is known for its:

  • Corrosion resistance: galvanized wire resists rust up to 100 times better than uncoated steel, making it highly durable and long-lasting.
  • Durability: the zinc coating is extremely durable and resistant to scratches from abrasion.
  • Versatility: many industries, including agriculture, recycling, and construction, use galvanized wire due to its high tensile strength, formability, and corrosion resistance.
  • Increased shelf life: hot-dip galvanized steel has a long life, reducing maintenance costs and offering a low long-term cost.

Common Uses

The recycling industry uses galvanized wire for baling recyclable materials that require long-term outdoor storage or experience exposure to wet conditions, such as:

Orchards and vineyards also use hi-tensile galvanized wire for trellising and tree support; farms use it for fencing and animal enclosures.

Our galvanization process

We use a meticulous hot-dip galvanization process to produce abrasion and corrosion-resistant wire. The process involves:

  1. Surface preparation: we clean the wire to remove impurities
  2. Pickling: we immerse the wire in an acidic solution to strip oxides and residue
  3. Fluxing: we soak the wire in a flux solution to prevent oxidation and form a uniform zinc coating
  4. Molten bath: we dip the wire into a bath of molten zinc at around 450°C (850°F)
  5. Alloy formation: iron-zinc alloys form for excellent adhesion and corrosion resistance
  6. Extraction: we slowly withdraw the wire from the zinc bath to produce an even coating
  7. Quenching: we rapidly cool the coated wire to solidify the zinc layer

Galvanization classes

The different galvanization classes indicate the thickness of the protective zinc coating. We offer both Class 1 and Class 3 galvanization:

  • Class 1 galvanization features a basic zinc coating of 0.28 ounces per square foot, providing 2–11 years of corrosion protection, depending on the environment
  • Class 3 galvanization offers a premium zinc coating nearly three times thicker than Class 1, using 0.80 ounces of zinc per square foot, resulting in 13–30 years of corrosion protection.

While both classes provide rust resistance, Class 3 galvanization is the best choice for harsh environmental conditions and heavy-duty applications.
