Precision-engineered tools and machines designed to meet the rigorous standards of France's railway infrastructure.
France operates one of Europe's most extensive and technologically advanced railway networks, creating sustained demand for high-performance rail welding materials and services.
France's TGV (Train à Grande Vitesse) network spans over 2,800 km of high-speed lines, with ongoing expansions under the Grand Paris Express and national infrastructure plans. These projects demand precision thermit welding for seamless, vibration-free rail joints capable of withstanding speeds exceeding 300 km/h.
Paris, Lyon, Marseille, Bordeaux, and Toulouse are all actively expanding urban transit systems. The Grand Paris Express alone — the largest urban transport project in Europe — will add 200 km of new metro lines and 68 stations, generating enormous demand for rail welding consumables and equipment through 2030 and beyond.
France's industrial zones, logistics hubs, and major seaports such as Le Havre, Marseille-Fos, and Dunkerque rely on heavy-duty crane rails and freight rail systems. Thermit welding is the preferred method for joining crane rails in these environments due to its durability and resistance to heavy cyclic loads.
SNCF Réseau, the French national rail infrastructure manager, invests over €3.5 billion annually in track maintenance and renewal. A significant portion of this budget is allocated to aluminothermic welding operations for replacing worn joints and restoring track geometry across the 28,000+ km national network.
France's commitment to carbon neutrality by 2050 is accelerating modal shift from road to rail. The French government's investment plan "France 2030" prioritizes rail decarbonization, driving new construction and electrification projects that require extensive welding operations for both mainline and regional networks.
Bilateral trade in rail technology components between China and France has grown steadily. Chinese manufacturers offering certified, cost-competitive thermit welding materials are increasingly recognized as reliable partners by French engineering firms, EPC contractors, and maintenance operators seeking to optimize procurement costs without compromising quality.

France is progressively replacing traditional jointed track with Continuous Welded Rail across its national network. CWR eliminates rail joints, reducing maintenance costs and improving ride quality. This transition directly drives demand for high-volume thermit welding operations, particularly for SNCF Réseau's track renewal programs.
European rail operators are increasingly integrating digital inspection and monitoring systems for weld quality assurance. RMTS aligns with this trend by providing materials engineered for consistent, measurable weld properties that comply with EN 14730 and UIC standards, facilitating seamless integration with digital quality management platforms.
The European Green Deal is pushing rail contractors to adopt more sustainable construction methods. Thermit welding, as a self-contained exothermic process requiring no external energy source, aligns well with low-carbon construction goals. RMTS continuously refines its welding powder formulations to minimize by-product generation.
France is a central node in the Trans-European Transport Network (TEN-T). Projects such as the Lyon–Turin Alpine base tunnel and the Atlantic Corridor upgrades require massive quantities of rail welding materials, creating long-term procurement opportunities for qualified international suppliers like RMTS.
France is investing in upgrading its freight rail capacity to reduce road transport dependency. Heavy haul applications demand thermit welding materials with superior tensile strength and fatigue resistance — core strengths of RMTS product lines, which have been tested on high-axle-load freight corridors internationally.
Post-pandemic supply chain disruptions have prompted French rail contractors and maintenance operators to diversify their supplier base. Chinese manufacturers with proven quality certifications and competitive pricing — such as RMTS — are increasingly considered as strategic secondary or primary suppliers to ensure supply continuity.
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.
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, including UIC 60, 75E, and crane rail profiles commonly used in France.
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 worldwide.
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 — fully adaptable to French and European standards.
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 and stay ahead of industry developments.
From high-speed mainlines to urban metros, seaports, and industrial crane rails — RMTS thermit welding solutions serve every segment of the French rail ecosystem.
Our track record of successfully delivered projects across Asia and beyond demonstrates our capability to serve demanding international markets including France.
As part of the Phase 2 expansion of Jakarta's Mass Rapid Transit (MRT) system, RMTS was contracted to provide aluminothermic welding solutions for the new underground and elevated tracks. The project involved welding 600 rail joints across a 12-kilometer stretch, connecting key areas of the city to reduce traffic congestion.
Our team worked closely with PT MRT Jakarta to ensure the welds met international safety standards. The project was completed on time, and the new line has been operating smoothly since its launch. Jakarta MRT officials highlighted the durability of the welds, which have withstood the high frequency of train movements and tropical weather conditions.
