Use of Zinc in Industry: Burlington’s Supply Chain 2026

The use of zinc in industry is fundamental to modern manufacturing, construction, and technological advancement. For businesses in Burlington, Vermont, and across the United States, understanding zinc’s industrial applications is key to optimizing processes and ensuring the durability of end products. In 2026, zinc continues to be an indispensable metal, driving innovation and supporting critical infrastructure.

This article explores the extensive industrial applications of zinc, from its unparalleled role in corrosion protection through galvanization to its use in alloys, die casting, and chemical compounds. We will examine how these applications impact various sectors, providing context for industries in Burlington and highlighting the importance of reliable zinc supply chains. Discover why zinc remains a strategic material for industrial progress in 2026 and beyond.

Galvanizing: The Primary Industrial Use of Zinc

By far, the largest industrial application of zinc is galvanizing steel. This process involves coating steel or iron with a protective layer of zinc, typically through hot-dip galvanizing, electrogalvanizing, or thermal spray methods. The zinc coating provides robust corrosion resistance, significantly extending the service life of steel structures and components. This application is critical across numerous industries vital to the US economy, including construction, automotive, and infrastructure.

Corrosion Protection Mechanism

Zinc protects steel in two primary ways: barrier protection and sacrificial (galvanic) protection. The zinc layer acts as a physical barrier, preventing corrosive elements like moisture and oxygen from reaching the steel surface. Even if the coating is scratched or damaged, exposing the steel, the zinc continues to protect the underlying metal through galvanic action. Zinc is more electrochemically active than iron, meaning it corrodes preferentially, effectively ‘sacrificing’ itself to protect the steel.

Applications in Key Industries

• Construction: Galvanized steel is used extensively in building structures, roofing, cladding, purlins, Z-purlins, wall studs, and bridge components. Its longevity and resistance to weathering are crucial for infrastructure projects in diverse climates, including those found in Vermont.
• Automotive: Vehicle bodies are heavily reliant on galvanized steel to prevent rust and corrosion, significantly extending their lifespan. Modern vehicles utilize advanced galvanizing techniques for optimal protection.
• Infrastructure: Guardrails, streetlights, signage, transmission towers, and pipelines are commonly galvanized to ensure durability and safety in exposed environments.
• Manufacturing: Many manufactured goods, from appliances and HVAC systems to machinery and metal furniture, incorporate galvanized steel components for enhanced durability.

The efficiency and cost-effectiveness of galvanizing make it the preferred method for corrosion protection, solidifying zinc’s indispensable role in industrial applications throughout 2026.

Zinc in Alloys and Die Casting

Beyond galvanizing, zinc is a crucial element in the formulation of various alloys, offering unique properties that are highly valued in industrial manufacturing. Its use in die casting, in particular, allows for the production of complex, high-precision parts efficiently and economically.

Zinc Alloys: Properties and Uses

Zinc is alloyed with other metals, primarily aluminum, to create zinc casting alloys, the most well-known being the Zamak series (Zamak 3, Zamak 5, etc.). These alloys exhibit excellent fluidity when molten, allowing them to fill intricate molds with thin walls, resulting in high-quality, dimensionally accurate parts. They also offer good tensile strength, impact resistance, and wear resistance.

• Automotive: Die-cast zinc alloys are used for grilles, door handles, mirrors, interior trim components, and various engine parts.
• Electronics: Housings for electronics, connectors, and internal components benefit from zinc alloys’ strength and conductivity.
• Hardware: Locks, hinges, gears, and appliance components are often produced using zinc die casting.
• Consumer Goods: Toys, sporting equipment, and decorative items utilize zinc alloys for their durability and finishing capabilities.

Brass Production

Zinc is a primary component in brass, an alloy of copper and zinc. The properties of brass can be tailored by adjusting the zinc content. It is valued for its strength, corrosion resistance, workability, and aesthetic appeal. Industrial applications include:

• Plumbing and Fittings: Valves, faucets, and connectors that require durability and resistance to corrosion.
• Electrical Components: Connectors, terminals, and conduits benefit from brass’s conductivity and strength.
• Machinery Parts: Gears, bearings, and machine tool components utilize brass for its wear resistance and low friction properties.

The versatility of zinc in alloy formation makes it a cornerstone material for industries requiring components with specific mechanical and physical properties, contributing significantly to product performance and longevity in 2026.

• Ceramics: Used in glazes to improve gloss, reduce thermal expansion, and enhance durability.
• Chemical Manufacturing: Serves as a precursor for other zinc chemicals and catalysts in various chemical reactions.

Zinc Sulfate (ZnSO4)

Zinc sulfate is another important industrial chemical with diverse applications:

• Agriculture: Used as a fertilizer additive to correct zinc deficiency in soils, promoting healthy plant growth and increasing crop yields. It’s also used in animal feed supplements.
• Mining: Acts as a depressant in froth flotation processes, helping to separate valuable minerals from ore.
• Water Treatment: Used as a corrosion inhibitor in cooling water systems and as a component in wastewater treatment.
• Rayon Manufacturing: Employed in the production of rayon fibers.

Other Zinc Compounds

Various other zinc compounds find niche industrial applications, including zinc chloride (used in soldering fluxes and as a wood preservative) and zinc sulfide (used in phosphors for screens and LEDs).

The strategic use of these zinc chemicals enables manufacturers to achieve desired product qualities, improve process efficiencies, and meet stringent performance standards across a wide array of industrial sectors in 2026.
