Precision-engineered rail tools trusted by infrastructure projects across Brazil — from São Paulo metro expansions to Minas Gerais mining railways.
Brazil operates one of South America's most extensive railway networks, spanning over 30,000 km. The country's ongoing infrastructure investment programs are creating significant demand for high-quality rail joint welding solutions.
Brazil's largest urban transit system continues to expand with multiple new metro lines under construction. Thermit rail joint welding is essential for creating seamless, continuous welded rail (CWR) in São Paulo's underground tunnels, ensuring smooth passenger rides and reduced maintenance costs across the extensive network.
The iron ore and steel industries in Minas Gerais rely heavily on heavy-haul freight railways. These industrial rail lines demand robust aluminothermic welding solutions that can withstand extreme loads and the harsh conditions of mining operations. RMTS thermit welding materials are engineered for exactly these demanding environments.
The Port of Santos — the largest port in Latin America — operates extensive crane rail infrastructure critical for container handling. High-precision rail joint welding ensures the structural integrity of crane rails under repeated heavy loading cycles, minimizing downtime and maximizing operational efficiency at Brazil's busiest seaport.
Rio de Janeiro's VLT (Veículo Leve sobre Trilhos) tram system has revitalized urban transport in the city center. Urban light rail projects require precision thermit welding to create smooth, noise-reduced rail joints that are compatible with both modern tram systems and the city's heritage streetscapes.
The Ferrovia de Integração Oeste-Leste (FIOL) is one of Brazil's most ambitious rail projects, connecting the agricultural heartland of Bahia to the coast. This 1,527 km freight corridor requires thousands of thermit welding sets to join rails across challenging tropical terrain, where temperature fluctuations demand high-performance welding materials.
Brazil's agribusiness sector — the world's leading exporter of soybeans, sugar, and beef — depends on efficient rail freight to move commodities from the Cerrado to coastal ports. Expanding agricultural rail corridors in Mato Grosso and Goiás are driving demand for reliable, cost-effective thermit welding solutions that can be deployed in remote field conditions.

Brazil's railway sector is undergoing a transformative period driven by privatization, infrastructure investment, and sustainability goals — all creating new opportunities for advanced rail joint welding technology.
Brazil's federal government has been actively privatizing railway concessions under the "Programa de Parcerias de Investimentos" (PPI), attracting billions in private investment. New concession holders are upgrading existing tracks and building new corridors, driving unprecedented demand for quality rail joint welding materials and equipment throughout the country.
Brazilian railways are rapidly transitioning from jointed track to Continuous Welded Rail (CWR) to improve ride quality, reduce maintenance frequency, and increase train speeds. This transition requires large quantities of thermit welding sets and skilled operators — creating a growing market for reliable suppliers like RMTS who can provide both materials and technical training support.
Brazil's commitment to reducing carbon emissions is accelerating the shift from road to rail freight. As one of the most energy-efficient transport modes, railways are receiving government incentives that translate directly into new track construction and maintenance contracts — all requiring thermit welding solutions that meet international quality and environmental standards.
RMTS have a highly skilled R&D team that works tirelessly to ensure that we produce thermit welding materials that meet the specific needs of each type of rail, including those used across Brazil's diverse railway network from urban metros to heavy-haul freight lines.
In addition to its strong R&D capabilities, RMTS actively participates in railway projects across China and abroad. The company collaborates with railway authorities, construction companies, and maintenance organizations to provide its expertise and materials for various projects.
By participating in railway projects, RMTS contributes to the development and maintenance of extensive railway networks. Whether in high-speed rail, urban transit systems, or conventional rail lines, RMTS offers its thermit welding materials and services to ensure the integrity and safety of rail infrastructure.
Furthermore, RMTS maintains partnerships with research institutions, universities, and industry experts. These collaborations enable RMTS to continuously strengthen its R&D capabilities in thermit welding technologies, ensuring solutions remain at the cutting edge of the industry.
RMTS offers two advanced crucible technologies, both proven in demanding rail environments across Brazil and globally.
Our main markets are in areas such as railway main lines, seaport crane rails, subways, trams, and high-speed railways. Aluminothermic welding plays a crucial role in these fields. No matter the scenario, RMTS welding technology, with its excellent performance, serves as a powerful support for promoting industry development and ensuring operational safety.
Thermit portion, sand mold, luting sand, ignitor are the main consumables for aluminothermic welding. 1 weld, 1 set consumables.
For example, 10km project, 12.5m long rail — Calculation formula: 10000/12.5×2 = 1600 sets
Take a look inside our 5,500+ ㎡ production facility where every thermit welding product is manufactured to the highest quality standards for Brazil and global markets.
RMTS is a passionate and progressive aluminothermic welding manufacturing company committed to supporting every stage of your rail project in Brazil.
Aluminum thermite welding, also known as aluminothermic welding or thermit welding, is a specialized welding technique that utilizes a chemical reaction to generate intense heat for joining aluminum components.
Preparation: Step 1 — Ensure the rail ends to be welded are clean, free from rust, and properly aligned. The gap size (space between two rails to be welded) shall be 26±2mm.
Thermit welding materials will be failed with water. All welding materials should be kept away from any moisture in storage, as well as in the welding process.
Thermit welding, also known as aluminothermic welding, requires careful handling and storage of its materials to ensure safety and optimal performance.
Offer a wide range of thermit welding materials, such as welding kits, sand mould, one shot crucible/long life crucible, luting sand, ignitor, ensuring consistent quality and reliable performance.
RMTS's strong R&D abilities, coupled with its involvement in railway projects, demonstrate the company's commitment to providing advanced thermit welding solutions that meet the specific demands of the railway industry.
