The Rebar Dilemma Amid Africa's Infrastructure Development Wave: Supply Challenges and Solutions in 2025
The African continent is experiencing a wave of infrastructure development, but a shadow looms: rebar, the backbone of construction, faces increasingly severe supply challenges. When the long steel production line at South Africa's largest steel mill permanently closed in March 2025, leaving 3,500 workers unemployed, the vulnerability of Africa's steel industry was fully exposed. A 12.74% surge in electricity costs, logistics costs exceeding international standards, and the impact of low-priced imported steel are putting pressure on the survival of African rebar.
I. Africa's Rebar Supply Dilemma
1. Shrinking Local Capacity and Cost Crisis
The closure of ArcelorMittal's long steel business in South Africa is by no means an isolated incident; rather, it represents a concentrated manifestation of the challenges facing the African steel industry. The closure announcement directly addressed four key pain points:
Economic weakness dampened demand
Rising energy and logistics costs
Low-priced imported steel (particularly from China) impacted the market
Lack of effective government policy intervention
A 12.74% energy price increase by Eskom, South Africa's state power company, and Transnet's refusal to negotiate logistics rates further weakened the competitiveness of local steel mills.
2. Mismatch between infrastructure demand and supply
Africa is experiencing a surge in infrastructure construction, with demand for rebar continuing to grow, from Kenya's Mombasa Railway to Nigeria's Dangote Refinery. While South African steel mills were shutting down their long product lines, Kenya's president announced a new mill, set to become the second-largest in sub-Saharan Africa, producing billets, coils, wire rod, and other products.
This shift in focus reflects the structural contradictions of Africa's steel industry: the paradox of growing demand and shrinking capacity.
II. Escalating trade barriers reshape the export landscape
Many African countries are reshaping the steel trade order through tariffs and legal measures:
South Africa: In 2020, it imposed a first-year safeguard duty of up to 54.04% on Chinese steel threaded fasteners, and implemented a three-year tiered tariff system (52.04% and 50.04%).
Kenya: Starting in 2023, a complete ban on Chinese steel imports was implemented. President Ruto stated this was "to protect local companies," and the country plans to increase its industrialization rate from 7% to 30% by 2030.
Tariff Mechanism: South Africa imposes a 15% VAT and tariffs ranging from 0% to 45% on all imported steel products, with no threshold. Even small orders are subject to tax.
Case Study: China's Chenggang successfully exported 2,600 tons of HRB400 rebar to Eritrea in seven sizes, ranging from 8mm to 25mm, all requiring a vanadium content of 0.1% or higher.
However, in the current trade environment, such transactions face higher barriers.
III. Rebar Price Fluctuation Warning for 2025
The global rebar market is entering a period of deep adjustment, with two major characteristics expected in 2025:
1. Downward Price Center: CICC predicts that the average rebar price will fall to 3,250 yuan/ton, a 6%-7% decrease from 2024.
2. Increased Volatility: Expected to fluctuate widely between 2,800 and 3,800 yuan/ton, driven by three major factors:
Steel mills' rapid transition from production cuts to resumption (high supply elasticity)
Declining steel use in real estate (estimated reduction of 20.75 million tons)
Limited increase in steel use for infrastructure supported by special bonds (only 900,000 tons)
IV. Solutions: Supply Chain Solutions for 2025
1. Localized Production Cooperation Model
The new Kenyan steel plant model offers a valuable example: Chinese technology combined with localized African operations. The plant is expected to create 1,500 direct and 9,000 indirect jobs, meeting the "Made in Africa" policy while addressing China's export barriers. The steel mill's product line covers billets, coils, and wire rod, forming a complete, closed-loop industrial chain.
2. Supply Chain Optimization and Cost Restructuring
Logistics Innovation: Establishing rebar transshipment hubs on the east and west coasts of Africa, using a "large ship to small ship" approach to reduce unit logistics costs.
Power Hedging: Signing long-term power purchase agreements (PPAs) with renewable energy suppliers to lock in electricity prices.
Tax Strategy: Utilizing the South African VAT formula (*VAT = 15% × (FOB price + tariff + 10% FOB price) * 3), optimizing FOB pricing and reducing the tax base.
3. High-End Products and Adaptable Specifications: The African market has specific requirements for rebar specifications. Develop precise specifications based on successful export cases:
Specifications (mm) Form Material Requirements Main Applications in Africa
8-10 Round Coil HRB400, Vanadium ≥ 0.1% Rural Low-Rise Buildings, Temporary Structures
12-16 Spiral Coil HRB400, Vanadium ≥ 0.1% Urban Residential Floor Slabs, Columns
20-25 Spiral Coil/Straight Bar HRB400, Vanadium ≥ 0.1% Bridges, Large Factory Structures
4. Policy Coordination and Regional Collaboration
Promoting the "Steel for Infrastructure" model: Chinese engineering general contracting (EPC) projects will prioritize the procurement of locally produced Chinese standard steel.
Participating in carbon emissions trading: Chinese steel mills can leverage advanced low-carbon technologies to generate carbon offset benefits (South Africa will launch carbon emissions trading for the steel industry in 2025).
Establishing a joint West African rebar reserve: stabilizing price fluctuations and addressing supply chain disruption risks.
With the last steel bar rolling off the production line at the Newcastle, South Africa, plant in early April 2025, the African steel era has not ended, but rather ushered in a new chapter. As the torch of the new Kenyan steel mill is lit in Mombasa, and as Hesteel Group's low-carbon steelmaking technology crosses the Indian Ocean and arrives in South Africa, a new rebar supply chain ecosystem is taking shape, integrating China's capital and technological advantages with Africa's localized needs. The price fluctuations in 2025 are not only market signals but also a countdown to the shift and upgrade of the China-Africa steel cooperation model.
History doesn't simply repeat itself, but it does rhyme. In 2009, Chenggang exported vanadium-containing rebar to Africa, with a vanadium content exceeding 0.1% per ton. 10 The key to breakthroughs in 2025 will again be that 0.1%—but this time it will require continuous improvement, including a 1 percentage point increase in local penetration, a further 0.1% reduction in costs, and over 0.1% in tax optimization. The laws of the steel jungle remain unchanged; only those who evolve survive.
