The welded steel tube market size was valued at US$ 191.23 billion in 2024 and is expected to reach US$ 274.25 billion by 2031; it is estimated to record a CAGR of 5.6% from 2025 to 2031.

Rise in Investment in Construction Industry Worldwide

The construction industry is growing rapidly in various countries across the globe, with a rise in government investments and an increase in demand for various construction projects. Countries such as the US, China, Mexico, Brazil, and India have the most significant construction businesses in the world. According to the Associated General Contractors of America (AGC), the US construction industry is growing with an investment of ~US$ 1.4 trillion per year. In construction, welded steel tubes are used in plumbing, heating, cooling, and fire sprinkler systems. They are corrosion-resistant, durable, and can withstand high pressure and temperature. Welded steel tubes are also used in the construction of buildings, bridges, and other large infrastructure projects. They provide strong, load-bearing elements in structural frames, supporting roofs, walls, and floors. The long-term construction sector is growing rapidly owing to the increasing government investment in infrastructure development. For instance, ~US$ 1.2 trillion in funding was passed by the Bipartisan Infrastructure Law in the US, and US$ 828.8 billion was passed by the EU infrastructure development fund in Europe. Steel tubes are commonly used as columns and beams in commercial infrastructure and industrial buildings. High tensile welded steel offers greater strength and the ability to withstand both compression and tension, making it ideal for vertical and horizontal load-bearing applications.

In Asia Pacific, the rising population is putting a strain on current infrastructure, highlighting the need for the development of new rail networks, residential structures, and roadways. Welded steel tubes are often used to construct scaffolding for construction sites, offering a secure, stable platform for workers at various heights. Their ease of assembly and strength make them an essential tool in large-scale construction. The construction industry in Asia Pacific was valued at US$ 4.36 trillion in 2022, representing 45% of the overall global construction industry. The investment is mostly in countries such as India, Japan, Australia, Singapore, Malaysia, and China. Steel tubes are used in the construction of columns and beams, providing essential load-bearing capacity for buildings and other structures. The tubes are often used in high-rise buildings, commercial structures, and industrial facilities because they can bear significant weight and resist bending. Rising governments and regulatory bodies invest in additional infrastructure development, which is proliferating the demand for welded steel tube products. India is one of the world's largest construction markets. A surge in construction activities in the country is driven by ongoing industrialization, increasing population, growing middle-class income, and increasing infrastructural developments. In the Union Budget 2022-2023, the Government of India allocated US$ 130.57 billion to enhance the infrastructure sector. According to the India Brand Equity Foundation Organization, India's construction sector contributes ~8% of India's GDP. India's construction sector was valued at US$ 126 billion in 2023. Welded steel tubes are commonly used in the construction of structural frameworks, including columns and beams, which provide essential support and strength to these buildings. They offer high load-bearing capacity, which is crucial for buildings in seismic zones or areas with high wind loads.
