Today, modern chemists must face the same problem that one element posed to the Egyptians thatshould have destroyed the pyramids. It’s that ubiquitous element that threatens everything made by humans: water. As frost formed inside the stone structure at night and expanded with the morning, slow cumulative damage should have been done to the pyramids. For many years, this mystery defied the explanation of archeologists, however was eventually solved. A detailed study concluded that ancient Egyptians relied on technology to defy the power of water: they had invented a primitive form of cement.

Water threatens the integrity of modern structures. Steel, the very backbone of modern civilization, rusts when it comes into contact with water. Technology has been the answer for modern man, just as it was for the pyramid builders. Various techniques have been developed to prevent steel from corroding. One of the most sought after by leading industries is galvanizing. Both long-lasting and cost-friendly, galvanized steel can resist rust for 70 years or more. The characteristics of the environment where it is used, and the thickness of the protective coat can influence the lifespan of the steel. Today, a sophisticated process known as hot-dipping is used to galvanize steel. Essentially, galvanizing adds a zinc-iron coating to the metal, forming a protective layer. The multi-step process described below gives galvanized steel its protective qualities:
1) The steel is cleaned in a degreasing solution.
2) After being cleaned, the steel is pickled by running through various tanks containing hot sulfuric acid.
3) The steel is then fluxed in an aqueous solution (typically zinc-ammonium chloride).
4) After the flux, the steel is galvanized through immersion in a vat of molten zinc.
5) Afterward, the steel is inspected for consistency and a complete coating.
Galvanized steel has a low, initial cost, and no need for maintenance. It also provides other important advantages:
• Rust resistance: The iron elements in steel are incredibly prone to rusting, but the addition of zinc acts as a protective buffer between the steel and any moisture or oxygen.
• Easy inspection: It is easy to tell how strong a galvanized coating is just by looking at it. There are also quick stress tests that can determine how thick the zinc coating is.
• Sacrificial anode: This ensures that any damaged steel is protected by the surrounding zinc coating. It does not matter if the steel section is completely exposed; the zinc will still corrode first.
• Longer life: With galvanization, a piece of industrial steel is expected to last 70 years in average environments and can last over 20 years with severe water exposure. No maintenance required.
Galvanization is part of a larger framework in steel preparation. Clients can benefit through facilities that can apply various processes to steel including hot-dipped galvanizing. That’s why National Galvanizing’s state-of-the-art facility enables pickling, galvanizing, galvannealing, and slitting, all in one location. As a joint venture between National Material L.P. and Heidtman Steel, National Galvanizing has an unparalleled structure for quality, high-speed supply that serves the automotive, heavy truck, agricultural, garage door hardware, and HVAC industries, among others.

Steel and Recycling: Fun Facts!

2020-08-06T19:53:22+00:00August 6th, 2020|News Blog|

Here at National Material Company, we thought we’d pause, reflect, and share some good news and fun, interesting facts about the steel industry.

In 2016, Azo CleanTech reported that steel is the most recycled material in North America. The metal comes not only from cans but also from construction scraps, automobiles, and appliances, and it can be turned right back into steel that can be used in the same applications.

Recycling is at the core of the steel industry’s commitment to sustainability. According to steel.org, the North American steel-making furnaces “consume nearly 70 million tons of domestic steel scrap in the production of new steel.” By using steel scrap to make new steel, the North American steel industry conserves energy, emissions, raw materials, and natural resources. This commitment drives the reduction of steel’s environmental footprint, while producing advanced, highly-recycled steel products that meet an advancing society’s needs.

Here are some fun facts about steel and recycling:

  • Steel products can be recycled repeatedly without loss of strength.
  • Recycling steel saves the equivalent energy to power about 18 million households for a year.
  • More than 80 million tons of steel are recycled each year in North America.
  • For every ton of steel recycled, 2,500 pounds of iron ore, 1,400 pounds of coal, and 120 pounds of limestone are conserved.
  • Almost 69 percent of all steel is recycled in North America each year – more than paper, aluminum, plastic, & glass combined. North America’s average steel recycling rate has been in excess of 60 percent since 1970.
  • More than 95 percent of the water used for making steel in North America is recycled.
  • One scrapped car produces more than four steel utility poles.
  • 95 percent of the steel taken from commercial construction demolition sites was recycled and made into new steel products in 2002.
  • 100 percent of a steel roof can be recycled. Asphalt roofs – zero percent. (Steel roofs provide your family with excellent protection against wind, water, snow, ice, and fire and are even hail-resistant. Asphalt roofs actually weigh twice as much as steel roofs. Steel roofs can last over 50 years, while traditional roofs last only 17 years!
  • Steel food cans are the most recycled food package. 24,000 community recycling programs in North America collect steel cans. Canned food is as nutritious as its fresh and frozen counterparts upon preparation! Canned goods do not contain preservatives!!
  • All 99 pounds of steel in the average major appliance can be recycled to make
    new steel products.

Also, according to Utah Recycles, there are many more encouraging examples of how the steel industry’s commitment to recycling is helping to save the planet. Steel only takes up to 100 years to fully decompose in a landfill, whereas it takes plastic 1000 years to break down (aluminum can take 200 years, tin can take decades)! Recycling steel takes 25% less energy and creates only 25% of the water and air pollution required to produce steel from raw materials. About 70% of all metal is […]

Galvanized Steel in The Agricultural Industry

2020-01-15T19:15:45+00:00January 8th, 2020|News Blog|

In the middle of the picture are 5 white, transparent bubble logos with green designs in the middle, from right to left: a water drop, a farmer with a shovel, a tall stalk of wheat, a tractor, and a sun.

Metal and Farming:  A Perfect Match

 

The union of farming and metalworking has led to many of civilizations technological and agricultural developments. Before the invention of farming, most early civilizations existed as gatherers and hunters. Because farming created the conditions in which people could settle, it ultimately contributed to the building of modern society and culture. Farming, and the stability farming provided humanity, led to the benefits of modernity: technology, politics, literature, the arts, and culture. Metal, like farming, helped to tilt the balance of power between mankind and nature towards mankind. Human beings could finally subdue the natural elements around them, which, beforehand, they seemingly had little to no control over.

Before the union of farm work and metal, farmers had inefficient tools to contend with the harsh conditions. These medieval farms only produced somewhere between 4.34 seeds for each seed of wheat sown. Entire village populations were constantly on the brink of starvation. Metalworkers introduced the iron plow to farmers, who had been using the ineffectual wooden plow. The new iron plows could cut through the heavy northern European soil, even during winter frost. This mingling of metal and farm work, among other technological/intellectual developments, led to the Enlightenment era and a population boom that reshaped the social order.

Today, the interaction between farming and metalworking continues to provide humanity with bountiful harvest. Although farms have become much more efficient, profit and competitive margins remain slim. Advances in metallurgy – like galvanized steel, are a keystone to modern farming operations by helping farmers to save time and money.

 

The Benefits of Galvanized Steel

 

Galvanized metal has been around for hundreds of years, although the methods for applying the zinc coating have become more sophisticated.

Galvanization improves steel’s longevity through a protective coating that prevents rust from forming. The process of hot-dip galvanizing creates a product with many benefits that other types of coatings don’t offer. For example, galvanized steel is:

  • Less expensive when compared with most treated steels.
  • Lower in maintenance cost than other coated metals – saving time on repairs and replacements.
  • Damage-resistant, very durable, and can withstand outdoor elements.
  • Self-healing in the way it’s coating provides automatic protection for damaged areas and will corrode preferentially to the steel, creating protection to the areas that are damaged.

Ready to use immediately upon delivery – it does not require additional preparation of the surface (painting/coatings, etc.) prior to installation.
