Global steel rebar demand to reach 201.56 million tonnes by 2031

The global steel rebar market is projected to expand from 152.96 million tonnes in 2026 to 201.56 million tonnes by 2031, representing a compound annual growth rate of 5.67%, according to a new report from Mordor Intelligence.

Market growth is being supported by increased infrastructure investment, urban construction, building upgrades and the transition towards lower-carbon steel production. Demand for durable and corrosion-resistant reinforcement materials is also influencing product development and investment across the steel industry.

Asia-Pacific remains the world’s largest rebar-consuming region. China and India continue to generate substantial demand, while construction activity in ASEAN is strengthening as foreign investment flows into transport networks, renewable energy facilities, data centres and other major infrastructure projects.

North American demand is also rising, supported by manufacturing reshoring, semiconductor facilities, renewable energy developments and public infrastructure programmes. Growth in industrial and non-residential construction is helping offset weaker housing activity in some markets.

Low-carbon steelmaking reshapes production

The transition towards electric-arc furnace steelmaking is emerging as an important market trend as producers seek to reduce emissions and increase the use of recycled scrap. However, fluctuating iron ore and scrap prices continue to pressure steelmakers’ margins.

Integrated mills may benefit when iron ore prices decline, while electric-arc furnace operators remain exposed to the availability and cost of high-quality scrap. Regional differences in raw-material supply, energy costs and government support are creating uneven competitive conditions among producers.

Interest in fibre-reinforced polymer bars is also increasing, particularly in coastal and high-salinity environments. Their corrosion resistance can help reduce maintenance requirements for bridges, seawalls and other infrastructure exposed to harsh conditions. Advances in hybrid materials and design standards are expected to support broader adoption.

Despite the development of alternative reinforcement materials, conventional reinforced concrete is expected to retain its dominant position because of its strength, versatility and established supply chain. Digital design, automated rebar fabrication and sensor-based structural monitoring are also improving construction efficiency and creating new opportunities for steel producers and fabricators.

The market covers deformed and mild rebar across residential, commercial, institutional, industrial and infrastructure applications. Production technologies include electric-arc, basic oxygen and induction furnaces.

As infrastructure programmes accelerate and pressure to decarbonise steel production increases, manufacturers will need to balance rising demand with volatile input costs, changing material requirements and stricter sustainability expectations.
