Introduction to Weathering Steel
Weathering steel is a high strength low alloy steel metal which contain copper as an alloying constituent. It is also known as ‘copper-bearing steel’ or general tradename ‘Corten’. These alloys form a rust-like oxide layer after a long time when exposed to weather, however, once developed, the oxide layer protects the metal and inhibits further corrosion and rusting. Weathering steel provides a greater resistance to rusting compared to typical low carbon steel grades. Weathering steel finds wide application in steel bridges, railway networks and structural architecture owing to its long-term performance, attractiveness, very low maintenance and economic benefits. It offers enhanced safety by eliminating the need for a protective paint system and a long-life span.
Market Size and Forecast
Increasing wide-scale applications of weathering steel in construction, architectural and transportation industries owing to its excellent mechanical properties are the significant factors boosting the market growth. The weathering steel market is anticipated to record a significant CAGR over the forecast period, i.e., 2020-2028. The market is segmented by application into building and construction, transportation, industrial, architecture and others. Among these segments, the segment for building and construction is anticipated to hold the leading share in the market on account of increasing investments in infrastructural development and growing construction activities all across the world. Moreover, high strength and load-bearing properties along with the ability of weathering steel to exhibit good aesthetic appeal over a period of time makes it a cost-effective choice in housing units and buildings.

Rapidly Growing Construction and Transportation Industry to Drive the Market Growth
The construction and transportation sector have potential growth and investment opportunities across all the world’s infrastructure activities. According to the American Road and Transportation Builders Association (ARTBA), the U.S. transportation infrastructure market is expected to grow at least 5 percent in 2020. Weathering steel is a widely used and crucial component in bridge construction, railway wagons, heavy-duty transportation and shipping containers. On the back of these, the market is predicted to grow over the forecast period.
Increased Demand in Architectural Applications and Excellent Material Properties to Boost the Market Growth
There is a significant rise in demand for weathering steel as a raw material in highway structures and art and architectural sculptures owing to its key features such as enhanced corrosion resistant, longer shelf life and extraordinary aesthetic appeal. Moreover, excellent properties such as superior strength, low maintenance, high toughness and tensile strength, load-bearing properties and high temperature resistance makes weathering steel a best material used in industrial purposes like heat-exchanger units and chimneys. This is anticipated to significantly expand the weathering steel market.
Harsh Environmental Conditions to Hamper the Market Growth
Despite of its favorable material properties, there is a severe impact of extreme environment on weathering steel such as rust, corrosion, reduction in fatigue life owing to its usage in regions of high concentrations of corrosive chemicals and industrial fumes. This is estimated to hinder the growth of weathering steel market in the future.
