According to a new report by UnivDatos, the Southeast Asia Galvanized Steel Market is expected to reach USD Million in 2033 by growing at a CAGR of 6.50% during the forecast period (2025- 2033F). The rapid construction and infrastructure growth, increasing automotive and appliance production, and rising demand for galvanized steel are the growth drivers in the Southeast Asia galvanized steel market. The wet climate in the area drives strong demand for corrosion-resistant products, and governments invest in industrial regions, railway and port reconstruction, and residential housing. The growing Foreign Direct Investment (FDI) is forcing steel processors to expand capacity and to produce more value-added coated products. The export potential is also gaining momentum as buyers worldwide shift sourcing to ASEAN.

Driver: Rapid Expansion of Construction and Infrastructure Projects

The rapid growth of construction projects and infrastructure development is driving demand for galvanized steel in Southeast Asia, as developers require materials that can withstand humidity, heavy rain, and prolonged exposure to corrosion. Additionally, Indonesia, Vietnam, and the Philippines are implementing highways, bridges, industrial parks, and low-cost housing projects, all of which depend on galvanized steel for framing, roofing, guardrails, and other structural components. Therefore, each new project will directly increase demand for coated steel, reinforcing long-term procurement pipelines at local mills. With ongoing increases in infrastructure expenditure, galvanized steel is the preferred material, further strengthening its position as the most dominant in the region.

Segments that transform the industry

• Based on product type, the market is segmented into hot-dip galvanized steel, electro-galvanized steel, galvannealed steel, and others. Among these, the hot-dip galvanized steel market held the dominant share in 2024. This is mainly due to its consistent reliability and wide-scale acceptance for corrosion protection across all Southeast Asian climatic conditions. Contractors and infrastructure developers use it in bridges, roofing, industrial facilities, and along the coast, where the structure's life is directly related to its life-cycle costs. With governments implementing massive public works projects, demand for long-lasting coated steel increases, compelling companies to expand production lines and enhance coating quality. On February 12, 2025, PT Tata Metal Lestari, a key player in Indonesia’s coated and painted steel industry and part of the global Tatalogam Group, awarded Tenova a contract for the supply of a new hot dip galvanizing line for zinc, aluminum, and magnesium alloy-coated steel coils. This advanced facility will be installed at the Sadang Plant in Cijaya, Kabupaten Purwakarta, Indonesia, and will have an annual production capacity of 250,000 tons.

Region that transforms the industry

• Indonesia is expected to grow at a significant CAGR during the forecast period (2025-2033) due to rising investment in large infrastructure projects, urban development, and an emerging automotive assembly sector. The rising demand for corrosion-resistant steel is due to long-term national projects, such as new highways, airports, energy facilities, and the new capital city. Therefore, companies are increasing their galvanizing capacity, enhancing product customization for construction purposes, and complying with government-implemented industrial policies. Moreover, galvanized steel manufacturers have a rapidly expanding market base as the country continues to industrialize and invest heavily in manufacturing. On September 3, 2024, South Korean steel giant POSCO and Indonesia's state-owned steel producer Krakatau Steel signed an important investment agreement in Indonesia. The two companies plan to invest a total of USD 3.5 billion to build blast furnaces and cold rolling mills in Indonesia. South Korean steel producer POSCO is aiming to join a large-scale construction project planned to move Indonesia's capital from Jakarta to the East Kalimantan province of Borneo.
