Arrival of Chinese Rails to Line 2-Green Exposes External Dependency and Reignites Debate on Why Brazil Doesn’t Manufacture Its Own Railway Material
The arrival of a large shipment of rails from China to the Line 2-Green of the São Paulo Metro has reignited an old debate: why does Brazil, owner of immense iron ore reserves and with several steel mills, not produce this type of material?
According to technical consultant Rubem Louzada, the answer involves industrial, economic, and strategic factors. He believes that the scenario can change, but it requires coordinated actions.
Complex and High-Engineering Production
Louzada explains that manufacturing rails is a process much more complex than producing other steel items. “Making rails is not like making rebar,” he states.

Instead of plastering the wall, Argentine architects left ordinary bricks exposed, without traditional mortar, without finishes, without paint, and created a perforated pavilion that looks like an art installation.

With 100 discarded pallets and simple tools, the project creates a 23 m² shelter, recycles wood used in the transport of humanitarian aid, and transforms temporary housing for refugees.

Scotland creates a brick made with over 95% recycled debris, eliminates kiln firing, and attempts to reinvent a piece used in construction for almost a thousand years.

In Taipei, 1.5 million recycled plastic bottles were saved from becoming waste, turned into building blocks, and formed a nine-story pavilion for an international exhibition.
The product requires pearlitic steel with 0.7% carbon, specific heat treatments, controlled microstructure, and minimal tolerances. Additionally, the bars reach up to 120 meters and require finishing and millimetric alignment.
To achieve this standard, advanced technology, metallurgical control, and a stable market that justifies the investment are necessary.
Insufficient Investment and Demand
The first challenge is financial. Building a modern rail factory requires over US$ 500 million (R$ 2.7 billion). To recover this amount, a constant and large-scale demand is necessary.
“Our average annual consumption is around 300,000 tons, varying according to the appetite of the concessionaires and the government. This is insufficient to justify a dedicated line like those that exist in China, Austria, Japan, or Poland,” he said.
Importing Rails Is Cheaper
Another point is the price. Countries with excess installed capacity offer rails at very low prices, with subsidized freight and long-term contracts. This combination makes importing more advantageous for companies and governments.
This situation, however, creates dependency and discourages domestic production. “Many Brazilian railway projects are literally ‘slit-eyed’ — waiting for Chinese rails to arrive on cargo ships,” Louzada comments.
Need for an Integrated Industrial Policy
For the consultant, the solution involves a robust plan that connects logistics and base industry. He suggests local content quotas, tax incentives, financing via BNDES, and demand guarantees as ways to reverse the situation.
“The world is looking at railways as a vector for decarbonization and efficiency. Brazil is too. But we are still relying on foreign rails. It’s time to turn this track around,” he concludes.
