The Energy Information Administration reported an energy output of 102. 92 quads and utilization of 100. 41 quads in 2022 in the United States. Approximately 81% of the primary energy produced in the same year came from fossil fuels. The expanding energy sector is identified as a driver for the weathered steel market.

Major companies in the weathering steel market are obtaining BIS licenses to manufacture structural weather-resistant steel, ensuring compliance with industry standards, improving product quality, and enhancing the durability and longevity of infrastructure projects subjected to harsh weather conditions. BIS (Bureau of Indian Standards) licenses are certifications granted by the Bureau of Indian Standards, which is India’s national standards body. These licenses confirm that a product, process, or service meets the specific standards established by BIS regarding safety, quality, and performance. For instance, in December 2022, Tata Steel Ltd, an India-based company, obtained the Bureau of Indian Standards (BIS) license to produce Structural Weather Resistant Steel (Corten Steel) in accordance with the standards specified in IS 11587. This type of steel usually contains elements such as copper, chromium, and nickel, which improve its resistance to atmospheric corrosion. The utilization of weather-resistant steel can lead to reduced maintenance costs and an extended lifespan for structures, thereby promoting more sustainable construction practices.

Major companies in the weathering steel market are securing funding to support the steel industry's transition toward decarbonization, aimed at improving the sustainability of their operations and developing advanced materials that minimize carbon emissions while ensuring performance and durability. Boston Metal's patented MOE technology employs electricity to convert iron ore into molten steel without generating CO2 emissions. This direct, one-step process is not only environmentally friendly but also adept at processing various grades of iron ore, making it a versatile solution for steel production. For example, in January 2023, ArcelorMittal SA, a Luxembourg-based steel production corporation, received an investment of $36 million in Boston Metal, representing a significant advancement in the steel industry's transition toward decarbonization. This funding is part of a larger $120 million Series C fundraising round aimed at enhancing sustainable steel production technologies. ArcelorMittal intends to lead the decarbonization efforts within the steel industry, which accounts for approximately 7% to 9% of global CO2 emissions from fossil fuels.

In December 2023, Nippon Steel, a Japan-based steel manufacturer and one of the largest steel producers globally, acquired U.S. Steel for $14.1 billion. Through this acquisition, Nippon Steel aims to increase its production capacity in the U.S. and enhance its manufacturing capabilities to address the rising demand for high-quality steel. BlueScope Steel Limited, an Australia-based company, also offers weathering steel. U.S. Steel, a U.S.-based manufacturing firm, developed CORTEN steel, a type of weathering steel that resists corrosion by creating a protective rust layer.

Weathering steel refers to a group of low-carbon steels that contain additional alloying elements, along with carbon and iron, developing a protective oxide film on their surface. These steels are utilized for exposed steel structures due to their ability to outlast plain carbon steel in outdoor environments. This characteristic eliminates the need for regular repainting and recoating.

The main types of weathering steel include corten-A, corten-B, and others (such as a604, a606, and others). Corten-A is a weather-resistant steel alloyed with copper, chromium, and nickel. Corten A, with added phosphorous, is particularly suitable for gas flue applications and aesthetic facias. However, it is not recommended for heavy load-bearing applications. Weathering steel is available in various forms, including plates, sheets, bars, and others (coils, rivets, stripes, tubes, and more). These materials come in different colors, both painted and unpainted. Weathering steel finds applications in various industries, including building and construction, transportation, art and architecture, as well as industrial uses like street lights.
