Steel is all around us. It supports the buildings we live in, the transportation we use every day, and the production of many of the technologies we depend on. It also creates infrastructure for our leisure time, including major entertainment venues.
And pig iron is the essential feedstock behind the high-grade steel used in those demanding applications.
For example, Sphere in Las Vegas is a music and entertainment venue that seats 17,600 people with a total capacity of 20,000. It is the largest spherical building in the world, rising 366 feet high and stretching 516 feet wide. The structure used 28,000 tons of steel, created with an estimated 5,600 tons of pig iron.
In a structure like this, steel has to carry heavy weight, supporting complex geometry, long spans and heavy loads. That kind of performance depends on steel with the right chemistry, purity, and consistency. Pig iron is required to make that possible.
Yet, the United States still faces a critical gap in merchant pig iron supply. Electric arc furnaces rely heavily on recycled scrap, but scrap alone cannot deliver the chemistry needed for high-grade steel applications. Pig iron provides the controlled purity and consistency that high-performance steel requires.
Whether the final use is a bridge, a skyscraper, or the world’s largest spherical venue, high-grade steel starts with the right pig iron input.
For decades, the United States has relied on imported pig iron to meet that need. North American Iron is working to change that by putting domestic resources to work and producing America First merchant pig iron for U.S. steel production.
