Weathering steel market size was estimated to grow at USD 876.14 million in 2020 and is expected to grow USD 1819 million by 2027 at a CAGR of 11% during the forecasting period of 2021-2027. Weathering steel has the corrosion resistance potent provides better resistance to corrosion rather than to usual low carbon steel grades. It is high force low alloy steel and has less than 0.3% carbon, which enables it to remain ductile and tough. It is widely used in signposts, bridges, highways and ports, fatigue resistance, durability and temperature are few important features of weathering steel. It is commonly used in buildings and doing outdoor decorations. It requires nominal maintenance and gives a more crucial product life cycle. It lessens the general lifecycle price and provides better safety by abolishing the requirement for a protective paint as well as long durability.
