What is Hot-Dipped Galvanized Steel?

Worthington Steel produces a type of galvanized steel known as hot-dipped galvanized steel. When producing hot-dipped galvanized steel, the steel is first cleaned to remove any surface impurities and then dipped into a bath of molten zinc. The zinc coating bonds with the steel by developing an intermetallic layer, which forms a protective layer that acts as a sacrificial barrier against moisture, chemicals, and other environmental factors that can cause steel corrosion.  The zinc coating sits on top of steel and isn’t chemically bonded, making it more prone to chips. Galvanized coating is best for non-surface critical applications requiring high corrosion resistance, such as culverts, grain bins, and guard rails. 

What Other Types of Hot-Dipped Coatings Does Worthington Offer?

Galvanneal

A galvanneal coating is produced by annealing galvanized steel. During the annealing process, the zinc bonds to the iron in the steel, producing a zinc-iron alloy. The galvanneal coating is smoother and harder than the galvanized coating, making it superior for exposed painted applications and more resistant to surface damage.   Galvanneal is often selected for car bodies.

Aluminized (type I,II)

"Aluminized Type 1" steel refers to steel coated with a layer of aluminum-silicon alloy through a hot-dipping process. This coating provides several benefits to the steel, including enhanced corrosion resistance, improved heat resistance, and increased reflectivity.  This protective barrier is beneficial in environments where exposure to moisture, chemicals, or high temperatures is a concern. Typical applications are heat exchangers and automotive exhaust systems.

"Aluminized Type 2" steel also utilizes an aluminum-silicon alloy, but there are differences in the coating processes and properties.  This type of coating is best for applications where extremely high-temperature environments and corrosion are significant concerns.  Aluminized Type 2 offers superior corrosion protection to aluminized Type 1.  Applications for type 2 would be heavy-duty industrial equipment exposed to harsh conditions and applications involving chemical processing where heat and chemical exposure are factors.

Galvalume

Galvalume is a coating made of zinc and aluminum. The name “galvalume” is a combination of “galvanized” and “aluminum – the two main components of the coating.  Before the steel is dipped into the zinc bath, it is coated with a thin aluminum-silicon alloy layer.  This aluminum-silicon coating provides several advantages over traditional galvanized coating: enhanced corrosion resistance, improved heat resistance, better formability, and a longer lifespan.  The heat tolerance and formability make this coating ideal for metal roofing and siding in hot climates.

Advantages of Galvanized Steel

Galvanized steel offers several advantages, making it a popular choice in various industries. Let's explore some of the key benefits:

Enhanced Corrosion Resistance

One of the primary advantages of galvanized steel is its exceptional protection of base steel substrate. The galvanization process involves applying a protective zinc coating to the steel surface, which forms a barrier against moisture, chemicals, and other corrosive elements. This zinc coating acts as a sacrificial layer, protecting the underlying steel from rust and corrosion. As a result, galvanized steel exhibits superior resistance to environmental factors, making it ideal for outdoor applications.

Longevity and Durability

Galvanized steel is known for its long-lasting durability. The protective zinc coating provides an additional layer of defense against wear and tear, extending the steel's lifespan. This makes galvanized steel a cost-effective choice in the long run, as it requires minimal maintenance and replacement. Whether used in construction projects, automotive manufacturing, or infrastructure development, galvanized steel stands the test of time.

Cost-effectiveness in the Long Run

While the upfront cost of galvanized steel may be slightly higher than that of other materials, its long-term cost-effectiveness must be considered. Galvanized steel's enhanced corrosion resistance and durability reduce the need for frequent repairs, replacements, and maintenance. Additionally, its resistance to rust and corrosion eliminates the need for protective coatings or sealants, further reducing costs. Its longevity and low maintenance requirements make it an economical choice for various applications. It also acts as a natural lubricant in roll-forming operations.

Considerations and Maintenance

Regarding galvanized steel, proper handling, and storage are crucial to maintaining its quality and effectiveness. Here are some guidelines to follow:

Handling

Handle with care: Galvanized steel is coated with a protective layer of zinc, which can be scratched or damaged if mishandled. Avoid dropping, dragging, or sliding galvanized steel to prevent any potential damage to the coating.

Storage

Store in a dry, well-ventilated environment. Moisture can accelerate corrosion on galvanized steel, resulting in white rust caused by zinc oxidization. Before fabricating, storing galvanized steel in a dry environment is essential to minimize exposure to moisture or humidity. Regardless, a well-ventilated storage area with low humidity levels is ideal for long-term storage—ceiling fans are an excellent solution to prevent white rust from occurring.
