Switzerland operates one of the world's most advanced and densely used rail networks. Meeting its exacting standards demands the highest quality thermite welding materials and equipment.
Switzerland's rail network carries over 1.3 million passengers daily and ranks among the world's most punctual systems. The Swiss Federal Railways (SBB/CFF/FFS), BLS AG, and numerous regional operators demand zero-compromise rail joint integrity — making precision thermite welding materials an essential industrial input across the country.
Switzerland's 5,300+ km SBB mainline network undergoes continuous maintenance and expansion. Thermite welding is the standard method for creating continuous welded rail (CWR), eliminating joints that cause noise, vibration, and accelerated wear in the high-frequency Swiss rail environment.
Switzerland's iconic alpine routes — including the Gotthard Base Tunnel (world's longest at 57 km) and Lötschberg Tunnel — present extreme thermal cycling challenges. RMTS thermite welding materials are formulated to maintain weld integrity under severe temperature fluctuations common in alpine rail environments.
Zurich, Geneva, Basel, and Bern are actively expanding their urban rail and tram networks. The Zurich S-Bahn, Geneva's CEVA cross-border rail link, and Basel's tram extensions all require precision thermite welding for seamless track joints in constrained urban construction environments.
Switzerland's Rhine-connected ports at Basel — including the Port of Basel (Rheinhafen) — operate heavy crane rail systems for freight handling. These industrial environments require robust thermite welding solutions capable of withstanding extreme dynamic loads from container cranes and heavy-lift equipment.
Swiss manufacturing and logistics hubs in the Mittelland region rely on private rail sidings connected to the national network. Pharmaceutical giants, chemical companies, and precision manufacturers in Basel and Zurich operate internal rail systems requiring regular thermite welding maintenance.
Switzerland's rail authorities invest heavily in proactive track renewal. The BAV (Federal Office of Transport) mandates regular rail replacement cycles, creating sustained demand for thermite welding consumables and equipment from certified suppliers meeting Swiss and EN standards.
The Swiss rail industry is at the forefront of adopting next-generation welding technologies to meet growing capacity demands and sustainability targets.
Switzerland's Rail 2050 strategy targets expanded high-speed connections across the country. New high-speed lines require continuous welded rail with zero-defect welds, driving demand for advanced one-shot crucible thermite systems capable of producing metallurgically superior rail joints at speed.
Swiss rail contractors are increasingly adopting automated welding process controls and digital quality verification. RMTS's precision equipment — including hydraulic tensioning machines and profile grinding systems — integrates seamlessly with automated track laying and inspection workflows.
Switzerland's commitment to net-zero by 2050 extends to rail construction. Thermite welding's inherent efficiency — no external power source required, minimal waste — aligns with Swiss environmental procurement criteria. RMTS continuously refines its thermite powder formulations to reduce slag output and improve burn efficiency.
Swiss rail operators are deploying IoT sensors and digital twin models to predict rail joint degradation. This data-driven approach increases demand for high-quality initial welds — since superior thermite weld quality directly extends the interval between maintenance interventions, reducing lifecycle costs.
Next-generation rail steels with higher hardness grades (R350HT, R400HT) used on Swiss high-traffic routes require precisely matched thermite welding powder compositions. RMTS's R&D team continuously develops rail-type-specific thermite formulations to match evolving rail material specifications.
Switzerland's central position in European rail makes cross-border interoperability critical. Projects like the Rhine-Alpine Corridor and connections to France's TGV and Germany's ICE networks require welding materials certified to both Swiss (SBB) and European (EN 14730) standards — a specification RMTS products are designed to meet.
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.





Our 5,500+ m² manufacturing facility in Tianjin, China is equipped with advanced production lines, quality control laboratories, and R&D centers dedicated to thermite welding innovation.
Our investment in research and development ensures that every product we deliver to Swiss rail operators and contractors meets the most demanding performance specifications.
RMTS has 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 — from standard UIC 60 profiles used across Switzerland's SBB network to specialist crane rails and high-hardness high-speed rail grades.
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 — including European rail infrastructure programmes.
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 — including Switzerland's alpine routes and cross-border connections — RMTS offers thermite welding materials and services to ensure the integrity and safety of rail infrastructure.
Furthermore, RMTS maintains partnerships with research institutions, universities, and industry experts in China. These collaborations enable RMTS to continuously strengthen its R&D capabilities in thermit welding technologies, ensuring our products remain at the cutting edge of rail welding science.
RMTS offers two proven crucible technology platforms, each optimised for different project scales, site conditions, and Swiss rail operator requirements.


Thermit portion, sand mold, luting sand, and ignitor are the main consumables for aluminothermic welding. 1 weld = 1 complete set of consumables.
For example, a 10 km project using 12.5 m long rail sections:
Calculation formula: 10,000 ÷ 12.5 × 2 = 1,600 sets required
For Swiss rail projects where rail lengths of 120 m are common (pre-welded panels), our team provides project-specific consumable quantity calculations and logistics planning to ensure zero downtime on critical track possession windows.
RMTS's strong R&D abilities, coupled with its involvement in railway projects globally, demonstrate the company's commitment to providing advanced thermit welding solutions that meet the specific demands of the railway industry. For Switzerland's rail sector, this means products that comply with EN 14730 aluminothermic welding standards, SBB technical specifications, and European railway interoperability requirements — backed by comprehensive on-site technical support and training programmes available to Swiss rail contractors and maintenance teams.
Swiss Rail Compliance: All RMTS thermite welding materials are available with full material traceability documentation, test certificates, and technical data sheets compatible with Swiss procurement requirements. Our team provides dedicated pre-shipment inspection coordination for Swiss-bound orders.
RMTS is a passionate and progressive aluminothermic welding manufacturing company. Beyond products, we deliver knowledge, training, and project-level expertise.
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 rail components. A Historical Perspective on its development informs best practice today.
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. Our process guides cover every step for Swiss site conditions.
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. Detailed site instructions are provided in English, German, French, and Italian for Swiss operators.
