Galvanized wire offers excellent corrosion resistance and longevity. Our galvanized wire undergoes a hot-dip galvanization process, which coats the underlying steel in a protective layer of zinc, enhancing its durability.

Galvanic corrosion
Matte appearance
More difficult to weld
While galvanized wire might cost more, it offsets costs associated with future wire replacement due to corrosion and breakage.
Galvanized wire has unparalleled corrosion resistance due to the protective layer of zinc that envelops the steel surface. This zinc coating acts as a sacrificial anode, shielding the underlying steel from corrosive elements and harsh environments.
Regular baling wire will rust when exposed to moisture, salt water, or other corrosive environments. While galvanized wire may also eventually rust, it maintains its structural integrity much longer than regular baling wire, making it the best choice for outdoor applications and marine environments.

Galvanization significantly extends the lifespan of steel wires, reducing the need for replacement and minimizing maintenance costs. The added zinc layer provides a protective barrier against corrosion and contributes to the wire's overall longevity. With proper care and maintenance, galvanized wire can last 50+ years, making it a cost-effective solution for long-term applications.
Unlike annealing, the galvanization process does not reduce the strength of steel, allowing galvanized wire to maintain its tensile strength and load strength. Hi-tensile galvanized wire is an excellent choice for heavy-duty baling applications, such as recycling copper, scrap metal, rubber tires, and e-waste.
Galvanized wire is used for many baling and non-baling applications, from agriculture and construction to manufacturing and recycling. Galvanized wire can handle diverse applications and environmental conditions, whether used for fencing, cable support, or as baling wire.
Galvanized wire's distinct matte finish lends an understated aesthetic appeal to projects where visual appearance matters. The zinc coating creates a uniform, silver-gray surface that complements certain styles and color palettes.
The galvanization process adds an extra layer to the wire's surface. As a result, galvanized wire tends to have a slightly increased weight and diameter compared to non-galvanized wire. This increase, albeit minimal, can impact baler compatibility, suitability for precision projects, and shipping costs.
While galvanized wire excels in strength and durability, it is less workable than black annealed wire. Galvanized wire is preferable for projects that require abrasion resistance, corrosion resistance, and strength.
The zinc coating limits the wire's elongation properties, making it less flexible and more prone to breakage when sharply bent. Wire that has undergone the annealing process should be chosen for applications that require elongation, high torsional strength, or intricate configurations.
The wire's protective zinc coating poses environmental concerns. When exposed to moisture, the zinc layer can gradually leach into the surrounding soil or water. Excessive zinc concentrations disrupt ecosystems and pose risks to aquatic life.
That said, zinc deteriorates at a slow rate. It is already a common element found in soil and water and is an important mineral for many organisms. The American Galvanizer's Association has found that most galvanized products leach zinc at a slow rate, posing little risk to the environment, humans, or other life.
To offset these risks, buy high-quality baling wire with an even coat of zinc, and recycle used baling wire.
Galvanized wire can accelerate the corrosion of other metals through a phenomenon known as galvanic corrosion. When galvanized steel wire comes into direct contact with dissimilar metals, such as aluminum or copper, in the presence of an electrolyte (e.g., moisture), it can trigger an electrochemical reaction. This reaction causes the less noble metal to corrode at an accelerated rate, compromising the integrity of the attached components or structures.
The zinc coating on galvanized wire can complicate welding. The zinc layer has a lower melting point than the underlying steel, which can lead to zinc vaporization and contamination of the weld pool. The zinc oxides formed during welding can also hinder proper fusion and result in weaker or less aesthetically pleasing welds.
We offer high-quality galvanized products to suit all applications. Our galvanized wire and bale ties are manufactured using premium-grade US steel and undergo a meticulous hot-dip galvanization process to produce superior corrosion resistance and durability. We offer the following galvanized wire products:
Metal wire is a versatile material. When choosing which type to use, from industrial projects to outdoor art, there are a lot of factors to consider. Two main differences between wire material and composition types are strength and durability. Choosing between galvanized wire and stainless steel for specific applications, the pulling forces on the wire, and the effect of the wire's environment on its material are what will guide your choice. How much tensile strength do you need, and what kind of moisture, chemicals, and other sources of degradation will it be exposed to? In addition, especially for larger projects, there are considerations of purpose, wear resistance, appearance, and price.
Tensile strength is an important advantage of stainless steel wire, which is made from steel that has been augmented with chromium. The mixture also improves the steel's rust resistance and heat resistance, increasing the applications for which it is suited. Stainless steel wire is excellent for harsh environments where it can be used without additional coatings in ovens, industrial cleaning baths, and other industrial processes. It can endure chemicals, saltwater, and other sources of corrosion over extended periods of time. It's good for most applications, including aerospace, with strong advantages over galvanized steel. Stainless is an excellent choice for projects that need its characteristics or where budgets allow.
Rather than incorporating corrosion resistance into the core metal, for galvanized wire, a hot-dipped zinc coating is the key. Zinc protects the steel, preventing damage to the wire core by the elements. It's a top choice for outdoor use, with hot-dipped galvanized steel lasting about 70 years typically. The American Galvanizers Association says that in the ocean, galvanized wire can typically last between 8 and 12 years. In freshwater, wire longevity can vary with the characteristics of the water. Galvanized wire has a cost advantage that should be factored into comparisons with stainless steel.
