The growing demand for visually appealing products with enhanced design flexibility, rising popularity of sustainable and eco-friendly construction materials, and increasing number of construction and infrastructure projects are some of the major factors propelling the market.

Weathering steel, also known as corten steel, is a high-strength, low-alloy steel that develops a rust-like appearance when exposed to the elements. It interacts with the atmosphere and offers a protective layer of rust forms on its surface while acting as a natural barrier against further corrosion. It assists in maintaining a distinctive aesthetic appeal to structures, providing durable protection, and reducing the need for constant maintenance. As it is widely utilized in outdoor architectural and structural projects, the demand for weathering steel is increasing worldwide.

At present, the rising demand for enhanced steel that offers structural integrity and visual appeal over a long period of time is supporting the growth of the market. Besides this, the increasing need for products that are resistant to atmospheric corrosion is strengthening the growth of the market. In line with this, the growing demand for long-lasting structures that withstand harsh weather conditions is positively influencing the market. Apart from this, the increasing adoption of weathering steel due to its cost-effectiveness is offering lucrative growth opportunities to industry investors. In addition, the rising utilization of steel that provides enhanced flexibility in design is bolstering the growth of the market. Furthermore, increasing advancements in the metallurgy industry are contributing to the growth of the market.
