Special Bar Quality (SBQ) Market Trends
The SBQ steel industry saw consistent scale, with worldwide market value rising from USD 27.11 billion in 2023 to USD 29.14 billion in 2024. Engineering‑steel consumption stood at 48 million tonnes in 2024, up from around 45 million tonnes in 2022. Verifiable supply additions included 1.5 million tonnes in North America and 2 million tonnes in Brazil and Argentina over two years. Rounds remain the flagship SBQ form, delivering around 40 %–45 % of global output (roughly 20–22 million t), followed by squares (~25 %, 30 %, ~15 million t) in 2024 operations. Automotive end-use consumes approximately 14 million t, heavy equipment 11 million t, agriculture 4 million t, and oil & gas 3.5 million t, with “others” (including aerospace, rail, tools) accounting for 9 million t—collectively over 60 % of global SBQ tonnage. Asia‑Pacific produced around 25 million t (~50 % global share), with China and India exporting over 15 million t in 2024. Europe maintained about 9 million t, contributing around 20 % of global volumes, with domestic recycled inputs at 25 %, reducing carbon intensity. North America’s consumption of 10 million t corresponds to nearly USD 8.3 billion worth of SBQ steel in 2023.
Market tightness persisted: global supply was roughly 50 million t, marginally higher than consumption, resulting in inventory-to-sales ratios of 1.2–1.4 months. North America exported around 5 million t of SBQ bars in 2023, while Asia‑Pacific imported roughly 8 million t, reflecting trade flows. Technological trends include heat-treatment capacity vaping (average lead times now 13 weeks, up from 10 weeks), and improved surface finishing reaching < Ra 0.8 µm in cold-finished bars (< 18 million t total), enabling tighter dimensional tolerances (< ±0.5 mm). Sustainable practices are growing, especially Europe’s 25 % recycled billet penetration. Additionally, Latin America capacity rose by 2 million t, while India added 1 million t after opening two new mills (4 to 6 total) from 2022–2024. These expansions correspond with rising SBQ tonnage gains of around 8–9 % in Latin America and Africa. Overall, SBQ supply closely tracks demand, signaling robust trend alignment.

Gerdau has strategically expanded SBQ capacity in Latin America and North America, supported by newly commissioned rolling and heat-treatment facilities that added 1 million tonnes between 2022–2024.
Investment Analysis and Opportunities
SBQ investment flows have surged in 2023–2024, as evidenced by mill expansions and greenfield projects across emerging economies. North America’s capacity grew by 1.5 million t, while Brazil and Argentina added 2 million t of rolling and finishing lines. India’s addition of 1 million t in SBQ capacity and China’s ongoing plant modernization (over 3 million t in heat-treatment and finishing upgrades) reflect a regional tilt towards value-added, domestically consumed offerings. Demand segmentation supports targeted investment: the automotive segment consumed 14 million t in 2024, with gearbox and drive shafts (11 million t), agriculture (~4 million t) and oil & gas (3.5 million t) collectively represent 30.5 million t—over 63 % of total SBQ usage. These stable volume bases offer visibility to investment returns via sector-specific mills or integrated value chains. Trade patterns provide another avenue. North America exported 5 million t, while Asia-Pacific imported 8 million t in 2023–2024. Export-focused plants—particularly those in Eastern Europe, Latin America or Southeast Asia—could capture shipment volumes and leverage regional warehousing. Equally, imports to China and India reveal insufficient domestic capacity to meet 15 million t local demand, indicating opportunities for joint ventures or greenfield mills.
Sustainability investments are gaining traction—Europe reported 25 % recycled billet input for SBQ in 2024. New eco-conscious SBQ mills that target 30 %–40 % recycled content with slag treatment and energy-efficient furnaces can appeal to automotive OEMs and energy sectors under carbon-pressure mandates. Technological investments focus on reducing supply chain stress. Lead times averaged 13 weeks, with 30 % delayed orders. Mills equipped with advanced heat-treatment lines, real-time logistics coordination, and inline finishing can reduce lead times to 8–10 weeks, increasing competitiveness. Investments in grinding, drawing, and sub-µm surface finishing can unlock premium pricing in aerospace and robotics segments. Finally, regional expansion potential is strong. Latin America grew SBQ supply by 2 million t, Africa consumption rose 9 %, and India added 1 million t in capacity. Investors targeting these regions can capture growth rates above global averages, diversify regional production, and hedge against currency and logistics volatility.
New Product Development
New product development in the Special Bar Quality (SBQ) market from 2023 to 2024 has been dynamic, driven by advancements in metallurgical engineering, sustainability demands, and evolving application requirements. Several manufacturers launched high-strength alloy SBQ grades, with tensile strength exceeding 1,200 MPa and yield strength above 1,000 MPa. One major North American mill began producing such grades specifically for the energy sector—serving drill string and downhole tool manufacturers—with an output of approximately 250,000 tonnes in 2024 alone. Parallel to this, demand for precision-engineered components led to the introduction of ultra-smooth cold-finished bars with surface roughness improved from Ra 0.8 μm to Ra 0.4 μm or better. Production of these high-finish bars reached 100,000 tonnes, with primary customers in aerospace and automotive precision shaft markets. In automotive applications, a micro-alloyed lightweight SBQ steel designed to reduce component weight by 15% was rolled out, achieving production of nearly 500,000 tonnes in 2024. This new grade was widely adopted by European and U.S. automotive OEMs for drivetrain shafts and transmission parts. On the sustainability front, European mills pioneered recycled-content SBQ billets with 40% scrap content, producing 200,000 tonnes and achieving CO₂ emission reductions of approximately 2% per tonne. This innovation aligns with increasing regulatory pressures and OEM sustainability goals.
Technological advancements also emerged in processing efficiency: one of the top U.S. mills installed an integrated heat-treatment and precision grinding cell with a capacity of 800,000 tonnes per year, boosting overall plant output by 30% and reducing defect rates from 3% to 1%. Inline monitoring systems reduced production lead times by up to 20%, an essential improvement given current industry average lead times of 13 weeks. Meanwhile, investments in short-cycle induction heat-treatment allowed for faster hardening processes across 600,000 tonnes of newly processed SBQ grades, particularly benefiting the heavy equipment and oil & gas sectors. Overall, new product developments in the SBQ market are increasingly focused on meeting stringent tolerance standards, delivering enhanced mechanical properties, supporting global sustainability goals, and achieving processing efficiencies—solidifying SBQ steel’s positioning in high-growth, high-performance market segments worldwide.
