Deformed Reinforcing Steel Bar Market Report 2025

The deformed reinforcing steel bar market size has grown strongly in recent years. It will grow from $37.95 billion in 2024 to $40.41 billion in 2025 at a compound annual growth rate (CAGR) of 6.5%. The growth during the historical period can be attributed to the rising global demand for infrastructure development, increased investments in residential and commercial construction projects, greater government expenditure on bridge and highway construction, accelerating urbanization and population growth, and a heightened emphasis on sustainable and earthquake-resistant construction materials.

The deformed reinforcing steel bar market size is expected to see strong growth in the next few years. It will grow to $51.22 billion in 2029 at a compound annual growth rate (CAGR) of 6.1%. The growth projected for the forecast period can be credited to the expanding use of precast concrete products, growing replacement and renovation activities, wider adoption of thermo-mechanically treated (TMT) steel bars, the emerging trend of prefabricated and modular construction methods, and rising demand from heavy engineering sectors. Key trends expected during the forecast period include the integration of automated production lines, advancements in corrosion-resistant coatings, improvements in design software, progress in modular and precast construction techniques, and enhancements in digital supply chain management.

The growing trend of smart cities and sustainable urban development is anticipated to drive the growth of the deformed reinforcing steel bar market in the future. Smart cities and sustainable urban development involve integrating technology, infrastructure, and environmentally responsible planning to improve the quality of life, efficiency, and sustainability of urban areas. This trend is driven by the need for cleaner, more efficient living spaces that minimize environmental impact, optimize resource usage, and improve quality of life through intelligent infrastructure. Deformed reinforcing steel bars play a crucial role in supporting smart cities and sustainable urban development by providing strong, durable structures that enhance resource efficiency, reduce environmental impact, and increase infrastructure resilience. For example, in February 2025, the Green Finance and Development Center, a China-based non-profit think tank, reported that the value of green energy building projects rose from USD 6.4 billion in 2023 to USD 10 billion in 2024. Consequently, the increasing adoption of smart cities and sustainable urban development is propelling the growth of the deformed reinforcing steel bar market.

Leading companies in the deformed reinforcing steel bar market are concentrating on creating innovative products, such as high-performance steel rebars, to deliver lighter structures and cost efficiencies in construction. High-performance steel rebar is engineered to offer enhanced strength, flexibility, and corrosion resistance, making it ideal for structurally demanding projects. For instance, in November 2022, GPH Ispat Limited, a steel manufacturer based in Bangladesh, introduced the GPH QUANTUM B600C-R, the country’s first high-strength grade 600 deformed reinforcing steel bar, designed to comply with international standards for structural integrity, durability, and long-term performance. This innovative product represents a significant advancement in Bangladesh’s steel and construction industry, providing superior tensile strength, improved bonding properties, and proven reliability for critical infrastructure such as bridges, high-rise buildings, and smart urban developments - contributing to a more durable and sustainable built environment.

In June 2024, White Cap Supply Holdings LLC, a US-based construction distribution company, acquired Rebar Solutions LLC for an undisclosed sum. This acquisition aims to strengthen White Cap’s rebar fabrication capabilities and extend its presence in the Mid-Atlantic region, enabling better service to industrial and commercial construction clients with a wider array of products and services. Rebar Solutions LLC is a US-based manufacturer and distributor of deformed reinforcing steel bars.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s recommendations and conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the construction sector, particularly in materials procurement and project costs. Higher duties on imported steel, aluminum, lumber, and machinery have driven up expenses for builders, contractors, and infrastructure developers, leading to increased project bids and delayed timelines. Construction equipment manufacturers face similar challenges, with tariffs on essential components and raw materials inflating production costs and squeezing margins. Additionally, retaliatory tariffs in international markets have curtailed exports of U.S.-made construction equipment and materials, further affecting profitability. The sector must now prioritize local sourcing, modular construction techniques, and supply chain diversification to control costs and ensure project viability amid ongoing trade uncertainties.

Deformed reinforcing steel bars are steel rods featuring surface ribs or deformations that are used to reinforce concrete. These ribs provide enhanced bonding strength between the steel and concrete, improving structural integrity, reducing slippage under stress, and increasing resistance to tension, bending, and shear forces in construction applications. They are employed in concrete structures to boost tensile strength and strengthen the bond between steel and concrete, ensuring overall structural stability.

The primary types of deformed reinforcing steel bars include carbon steel, alloy steel, and stainless steel. Carbon steel is a type of steel mainly composed of iron and carbon, with minimal amounts of other alloying elements. Various manufacturing methods are used, such as hot rolling, cold drawing, thermo-mechanical treatment (TMT), and quenching and self-tempering (QST). Carbon steel bars come in multiple diameters, including 6 mm, 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, 25 mm, 32 mm, and others. Their applications include concrete reinforcement, bridge construction, road and highway projects, precast concrete products, as well as retaining walls and foundations. These bars serve several end users, including the construction sector, infrastructure development, commercial and residential projects, and heavy engineering.
