Acrylic Coating

We offer an acrylic topcoat (at G30 - G120) that further enhances corrosion protection and helps keep your steel looking brighter for longer. It also helps improve lubricity for roll forming and stamping.

In-House Coating Lines

By coating in-house to your exact specifications, we maintain precise control over thickness, coating weight, and surface for consistent, repeatable results. It also allows us to coat hot and cold rolled steel, apply differential coatings, and galvanneal for post-painted parts.

Types of Galvanized Steel

It Starts With the Steel You Choose—And the Company You Trust

  • Hot-Dipped Galvanized

    Hot-dipped galvanizing helps steel resist rust, preserve its appearance, and last longer in outdoor and harsh environments. Applying a thin layer of zinc directly to steel provides enhanced corrosion protection. This helps protect the quality and performance of the steel, lengthening the life of parts and products.

  • Galvanneal

    Galvanneal is steel coated with zinc and annealed to form a zinc-iron alloy, creating a smooth, matte surface that's easy to paint and weld. It offers strong corrosion resistance and is commonly used in automotive, appliance, and construction applications.

  • Hot-Dipped Galvanized + Acrylic Coating

    Hot-dipped galvanized steel with an acrylic topcoat combines a zinc layer for corrosion resistance with a clear finish that adds additional protection against moisture, chemicals, and wear. It also delivers a smoother, glossier finish for a cleaner, most polished look.

  • Aluminized & Additional Topcoats

    Aluminized steel is coated with an aluminum-silicon alloy for strong heat and corrosion resistance. Additional topcoats, such as chemical treatments, are available to enhance adhesion and surface durability, making them ideal for high-temperature and demanding environments.

Delivery Methods and Grades

A Closer Look at Steel Grades & Common Formats

  • Steel Grades
    Steel grades vary by strength, formability, and composition. From carbon to high-strength and ultra-high strength options, each grade is tailored to meet performance, processing, and application needs across a range of industries.
  • Configured Blanks

    Pre-cut, flat, geometric shapes are delivered ready for forming. Focus your operations, save manufacturing steps, eliminate die and press maintenance, maximize material use, and add flexibility with multiple ship-tos from a central location.

  • Slit
    Standard steel coils are cut to narrower widths or split into smaller PIW steel coils.  In addition, we can meet exacting width tolerance and dimensional specs for manufacturing, packaged to your requirements. This is ideal for high-volume part manufacturing.
  • De-Coiled / Cut-To-Length Sheet

    Steel cut to your size requirements for pattern cutting. Whether standard sizes for laser cutting (4’x8” or 5x10’) or custom for your requirements , we ensure it performs in terms of flatness and consistency when you go to form your parts. Our inline temper mill at our pickle line and state of the art leveler ensures reliable quality. Typically, fabricators consume cut-to-length sheets due to their demand volume, machine capabilities or type of part they want to economically fabricate.

  • Full Coil

    Before steel is slit, it is referred to as a full coil—regardless of whether it’s hot rolled, cold rolled, or coated (such as galvanized, galvannealed, or aluminized). These coils are typically large, weighing between 16 and 20 tons, and require heavy-duty equipment for handling and processing. Full coils are commonly ordered by manufacturers producing large, high-volume parts or by companies that perform their own slitting or de-coiling in-house.

Product Breakdown

Understanding Galvanized Steel

Galvanized steel is a go-to solution for industries that demand strength, corrosion resistance, and long-term performance, but understanding your options is key. In this guide, we break down what galvanized steel is, where it's used, and why it continues to deliver value across applications. Explore benefits, coating types, and what sets us apart.

Improving Galvanized Performance

Acrylic coating protects more than appearance.

We were curious. We knew acrylic coating helped prevent the formation of white rust on galvanized. But how much? And could we find other reasons to use it? Our Materials Support team tested acrylic vs. chromate. Read to learn why acrylic is the best choice for a variety of manufacturing processes and applications.

Reducing Steel Costs

Cutting costs by switching from cold- and hot-rolled galv

Reducing the cost of galvanized steel isn't always as simple as switching materials. In this case study, see how manufacturers evaluated the shift from cold rolled to hot rolled steel and how Worthington Steel used advanced analysis to minimize risk and uncover smarter cost-savings opportunities.
