What is Galvanizing?

Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing. 

Galvanized steel is among the most popular steel types because of its extended durability, having the strength and formability of steel plus the corrosion protection of the zinc-iron coating. The zinc protects the base metal by acting as a barrier to corrosive elements, and the sacrificial nature of the coating results in a long-lasting and high-quality steel product. 

This versatility makes it applicable to a variety of projects and industries, including agriculture, solar, automotive, construction, and so on. Below, we aim to provide a comprehensive description of how galvanized steel is processed, different galvanization methods, its benefits, and how it is used in these various industries.

The steps in the galvanizing process are as follows:

  • The steel is cleaned in a degreasing solution
  • After being cleaned, the steel is pickled by being lowered into a vat of diluted hot sulfuric acid
  • The steel is then fluxed in an aqueous solution (typically zinc-ammonium chloride)
  • After the flux, the steel is galvanized through immersion in a vat of molten zinc
  • Afterward, the steel is inspected for consistency and a complete coating

What are the advantages of galvanized steel?

Many different industries utilize galvanized steel primarily because it has such a wide array of benefits for industries to take advantage of, including having:

Low initial cost compared to most treated steels. In addition, galvanized steel is immediately ready to use when delivered. It does not require additional preparation of the surface, inspections, painting/coatings, etc. sparing companies more costs on their end.

Longer life. With galvanization, a piece of industrial steel is expected to last more than 50 years in average environments, and can last over 20 years with severe water exposure. There is no maintenance required. The increased durability of the steel’s finished product also increases the product’s reliability.

The sacrificial anode ensures that any damaged steel is protected by the surrounding zinc coating. It doesn’t matter if the steel section is completely exposed; the zinc will still corrode first. The coating will corrode preferentially to the steel, creating a sacrificial protection to the areas that are damaged.

Rust resistance from the zinc coating. The iron elements in steel are incredibly prone to rusting, but the addition […]

10 Fun Facts You Didn’t Know About American Steel and the Steel Industry

2019-09-12T18:25:28+00:00 June 24th, 2019|News Blog|

Clark Kent shedding his businessman persona he pulls his business suit away from his chest, exposing the powerful man of steel - Superman’s signature “S” logo

Looking up at the giant lattice-shell steel art structure known as the “Geodesic Dome” outside Montreal environmental museum “The Biosphere” on a clear blue skied day.

After achieving the mass production of steel, American steel industrialists pushed steelmaking to greater innovative levels. By the year 1920, 60 million tons of American steel were circulating around the world annually, making the United States the biggest global player in the steel service industry. Steel processing became a bulwark of the economy, engraving itself into the nation’s identity.

Today, National Material Company carries on the metal service and steel processing tradition. With the following 10 little-known facts, we salute those who paved the way by transforming the world through metal work.

  1. The Man of Steel could have been the Man of Tungsten.

But that doesn’t exactly roll off the tongue, now does it? According to Thaddeus Howze — author, editor, podcaster,  and self-proclaimed answer-man on all things comics –Superman got the name Man of Steel because steel was the most common of the strong metals: Steel, Titanium, Tungsten and Inconel. (It may also have something to do with the fact that “Man of Steel” is much snappier than its clunky counterparts.)

Superman was created to symbolize the extraordinary capacity of the everyday man. Thus, steel won out as metal of choice because of the household name it had made for itself, thanks to the wide proliferation of the steel industry at the time.

“Superman was a ‘man of steel’ stronger than anything you could imagine, and yet something as close as the building you were standing in or the car you desired and one day hope to own […] Steel was everywhere and steel was the king of industrial metals during this period [1940]. Steel wasn’t just the metal of tomorrow; it was also the metal of yesterday. Places in the world that had developed steel before modern industries had long-lasting cultures and it was the development of steel which made the industrial age what it was.”( Source: Quora)

2. Showers, Star Wars memes, and steel.

The month of May is well-known for its rain showers. And Star Wars enthusiasts rejoice on May the Fourth Be with You. And let’s not forget – steel.

Yes, that’s right. In the 1960s, as the nation infused steel into its structure and character, Lyndon Johnson saw it fit to raise a pedestal for steel in the pantheon of American achievement.  Therefore, he designated May as a national month for celebrating the steel industry.

“Steel is the core of industrial America. It has helped to make American productivity and technology the wonder of the world. This vital product which we produce in unmatched abundance is basic to our economy and essential to our security. It supports our buildings, spans our rivers, arms our fighting men. It […]

NMC Partner Taber Extrusions Offers Friction Stir Welding

2020-04-01T21:25:09+00:00 June 20th, 2019|News Blog|

Black and white closeup image of the tip of a friction stir-welder, which resembles the tip of a drill, with Taber Extrusions’ official inverted gold triangle logo and the words, “Introducing Friction Stir-Welding.”

National Material partner Taber Extrusions of Russellville, AR. and Gulfport, MS. have announced the addition of Friction Stir-Welding capabilities to their existing portfolio, which currently includes aluminum extrusions, fabrication, billet casting, and micro-extrusions.

The addition of in-house FSW capabilities positions Taber as a vertically integrated supplier of FSW panels and assemblies previously unseen in North America. This new technology allows for finished product applications in military, bridge building, railroad refrigerated containers, and more – and brings with it the technological capacities to develop new products.

Eric Angermeier, President of Taber Extrusions, says:

Besides the additional jobs and revenue this expansion will bring to our central Arkansas community, we are very much looking forward to Taber’s new horizons into technology and product development. The welder will be housed in a new 60,000 square foot expansion to our current Russellville facility. This equipment further promotes our strategy of moving Taber toward being a solutions-oriented company offering highly engineered products.

This Friction Stir-Welder, with the latest technology, is purposely built for the long, wide extrusions being produced on our current extrusion presses. This process gives us the added benefit of vertical integration allowing us to not only better serve our existing customers, but gives us the opportunity to develop new markets and products.

Sometimes described as more of a forging process than actual welding, Friction Stir-Welding is a solid-state joining technique used to combine metals not easily fused with traditional welding. Ideal for metals such as aluminum, copper and other metal alloys, FSW is commonly used in the aerospace, rail, automotive, shipbuilding, transportation and marine industries. Friction Stir-Welding makes possible high-quality welds with minimal distortion. It is also a process that can be easily automated, making it an ideal solution for industrial use.

Taber Extrusions recently hosted a ground-breaking ceremony which included State Representative Steve Womack amongst other state and local leaders.

Congressman Steve Womack described how he sees Taber’s role from a national perspective, “The expansion of an existing company such as Taber Extrusions means a lot more than the location of a new company. It means that Taber is in the right place and has what it needs to succeed. Taber plays an important role in the defense of our nation with products that are an asset to our defense capabilities.”

Taber historically provides for many industries, including aerospace, shipbuilding, infrastructure, automotive, as well as military and defense.

Taber is already known for their wide range of capabilities, both broad and unique, and Mayor of Russellville Richard Harris thanked Taber for choosing Russellville as their location, “The fact that you chose to expand and add new technology here is the highest compliment […]
