Costa Rica is currently experiencing a transformative phase in its national logistics and public transport networks. Led by the Costa Rican Institute of Railways (FECOSA), the nation is prioritizing the modernization of its rail corridors to connect agricultural heartlands with major global export gateways. The key focus remains on upgrading the Atlantic and Pacific networks, facilitating high-capacity freight transit to the APM Terminals in Moín, Limón, and the port of Caldera.
In addition to freight, the ambitious metropolitan electric train project (Tren Rápido de Pasajeros - TRP) aims to revolutionize transit across the Greater Metropolitan Area (GAM), linking San José, Alajuela, Heredia, and Cartago. In this tropical environment characterized by high humidity, intense rainfall, and seismic activity, the demand for high-integrity rail joints is paramount. Traditional mechanical joints are rapidly being replaced by Continuous Welded Rails (CWR) using advanced thermit welding.
To meet the stringent safety and durability parameters required by international financing bodies and local authorities, rail joint welding solutions must carry CE Certification. This certification ensures that thermit portions, sand molds, crucibles, and alignment tools perform predictably under extreme thermal expansion and mechanical loads, preventing rail failures and reducing long-term track maintenance costs.
RMTS is a manufacturer specializing in railroad thermit welding materials, based in Tianjin, China. With a factory spanning 5,500+㎡ and 30+ professionals dedicated, we are committed to delivering reliable and efficient thermit welding solutions to clients across the globe. Our products are designed to meet the highest industry standards, ensuring durability and performance in various applications.
We understand that successful welding projects require not only high quality products but also expertise and knowledge. That’s why we offer comprehensive on-site training programs to help our clients master the thermit welding process, enabling them to achieve optimal results and build a strong reputation in their respective fields. Additionally, our experienced team provides project welding instruction services, offering hands-on guidance and support to ensure seamless execution, no matter where the project is located.
Driven by a customer-centric approach, RMTS is dedicated to fostering long-term partnerships by delivering exceptional products and services tailored to the unique needs of our clients. Whether you are looking for reliable thermit welding materials, expert training, or project support, RMTS is your trusted partner in achieving welding excellence.
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.
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 China's extensive railway network. 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 the rail infrastructure.
Furthermore, RMTS maintains partnerships with research institutions, universities, and industry experts in China. These collaborations enable RMTS strengthens its R&D capabilities in thermit welding technologies.
Eco-friendly, single-use crucible system that minimizes dynamic slag inclusion and optimizes heating consistency during pour phases. Perfect for rapid deployment in Costa Rica’s mountainous rail links.
Multiple-use crucible lining designed to withstand up to 50-80 pours under high temperatures, reducing cost-per-weld in large-scale maintenance depots and port crane rail installations.
Seaport operations require specialized crane rails (e.g., A75, A100, A120 profiles) to carry massive container cranes. RMTS provides customized sand molds and high-strength thermit portions designed to handle the heavy, concentrated wheel loads at APM Terminals Moín.
Urban transit networks demand low-vibration and low-noise track structures to minimize environmental impact in residential zones. Our CE-certified rail joint welding ensures smooth joints, reducing noise pollution in the San José metropolitan area.
Costa Rica's topography features steep gradients and sharp curves. Continuous Welded Rails (CWR) joined with RMTS high-precision thermite welding powder resist lateral forces and thermal buckling caused by sudden weather shifts.
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.
Formula for Project Planning:
For example, 10km project, 12.5m long rail:
Calculation formula: 10000 / 12.5 × 2 = 1600 sets
This formula helps Costa Rican contractors precisely forecast logistics, import customs clearance needs, and warehousing requirements for major construction projects. Having a reliable supplier with consistent stock ensures that railway extensions do not suffer from downtime due to component shortages.
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.
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 fail 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 is a passionate and progressive aluminothermic welding manufacturing company providing global technical training and onsite instruction.
