2 Square Metal Tube Market Growth Drivers and Restraints
The expansion of the construction and automotive industries is the core driving force for the growth of the square metal tube market. With the development of social economy, the scale of the global construction market continues to expand. According to Statista, the global construction industry revenue was US$6.4 trillion in 2020 and is expected to exceed US$14.4 trillion in 2030.
With the rise of the concept of green building, construction companies are using more sustainable building materials, and the demand for square metal tubes as structural components has increased significantly. Whether it is the main frame of the building or decorative balcony railings, metal ceilings, etc., square metal tubes are indispensable, which makes the demand for square metal tubes in the construction field continue to rise.
In the automotive industry, the increase in people’s disposable income and the development of new energy vehicles have driven the continuous expansion of the global automotive market. The global automotive manufacturing market is worth about US$2.86 trillion in 2021 and is expected to grow to about US$2.95 trillion in 2022. Square metal tubes are used to manufacture the basic chassis frame in automobile manufacturing due to their durability. On average, each car requires 900kg of automotive steel. The development of the automotive market has driven the growth of demand for square metal tubes.
The square metal tube market faces many restrictive factors. International friction brings trade risks. Under the background of economic globalization, international trade forms are complex, and the square metal tube market is deeply affected. For example, since 2018, Sino-US trade frictions have intensified, and square metal tube-related products and their production equipment may be subject to tariffs.
If companies cannot transfer costs to downstream customers, net profits will be affected. At the same time, international trade protectionism has intensified, and square metal tube products may also be subject to anti-dumping and anti-subsidy investigations. Raw material price fluctuations cannot be ignored. Square metal tube production relies on raw materials such as iron ore, scrap steel, and bauxite. The unstable supply and price have a huge impact on corporate profitability.
The company’s raw material procurement depends on major suppliers. If there are problems with the cooperative relationship or the supplier’s operating and financial conditions, the company’s raw material procurement will be affected. Moreover, rising raw material prices will increase production costs, compress product profit margins, and force companies to adjust their production and operation plans. In addition, macroeconomic fluctuations have a significant impact on the square metal tube market. Its products are widely used in construction, automobiles, engineering machinery and other fields. These industries are greatly affected by macroeconomic policies, economic growth rates and industrial policies.
When the economy is booming, the demand for related industries is strong, and the market demand for square metal tubes increases; when the economy is sluggish, the market for related industries shrinks, and the demand for square metal tubes decreases accordingly. Fierce market competition also restricts market development.
The square metal tube industry is highly competitive. Many companies have increased their investment in research and development, product innovation, channel construction, and customer relationship management to compete for market share. Due to their lack of technical, channel and brand advantages, small and medium-sized enterprises often compete at low prices and even lower product quality standards. This not only affects the overall product quality of the industry, but also exacerbates the disorder of market competition, which is not conducive to the healthy development of the market.
3 Technological Innovations in the Square Metal Tube Market
Technological innovation is an important driving force for the development of the square metal tube market, which is mainly reflected in production automation, green production and product performance improvement. The process of production automation is accelerating. With the increase in labor costs, enterprises are facing huge cost pressure. The progress of automation technology has brought a turning point for enterprises.
By improving the level of intelligent manufacturing, the whole process from raw materials to finished products can be automatically controlled. With the help of management innovation means such as digital smart factories, process intelligent service platforms and computer-aided design, enterprises can not only reduce labor demand, but also improve production efficiency, optimize product quality, strengthen cost management, and promote enterprises to develop in the direction of intelligence and unmanned.
Green production technology has become an inevitable requirement for the development of the industry. Under the background of increasingly stringent environmental protection supervision, the treatment of wastewater, waste gas and solid waste generated in the production process of square metal tube enterprises has become a key issue. For example, in the manufacturing process of steel square tubes, zero emission of pickling process is an inevitable trend for future development. Enterprises must comply with environmental protection laws and regulations and strengthen the optimization of green production processes to reduce the impact on the environment and achieve sustainable development. Product performance research continues to deepen.
Under the pressure of market competition, enterprises increase R&D investment to enhance product competitiveness. With the increasing awareness of environmental protection, lightweight cars have become a trend. Square tubes made of high-strength steel can reduce the weight of the car body and reduce fuel consumption while ensuring the safety performance of the car. Therefore, enterprises continue to strengthen the research on high-strength steel square tubes. In addition, for different application environments, such as chemical, oil and gas, and marine environments, enterprises actively carry out corrosion resistance research on square metal tubes to meet the diversified needs of downstream customers.
Corporate mergers and acquisitions are an important means to optimize resource allocation and enhance competitiveness in the square metal tube market. Some companies achieve scale expansion and business expansion through mergers and acquisitions. Nucor’s acquisition of steel shelf manufacturer Hannibal Industries has enabled Nucor to enter new market segments, expand business areas, and enhance market competitiveness in related fields. At the same time, there are also companies whose merger and acquisition plans have been terminated, such as Sweden’s SSAB’s abandonment of the acquisition of Tata Steel’s Dutch plant. This event reflects the various uncertainties faced by companies in the process of mergers and acquisitions, including financial pressure, market changes and other factors that will affect merger and acquisition decisions.
