Engineered for European rail profiles (such as 49E1, 54E1, 60E1, 60E2) and heavy crane track standards (A75, A100, A120) across maritime and municipal networks.
Understanding Northern Germany's largest transport nexus, port rail infrastructure, and continuous welded rail requirements.
The Free and Hanseatic City of Hamburg represents one of Europe's most pivotal intermodal hubs. At the center of this dynamic industrial region lies the Port of Hamburg (Hamburger Hafen) and its critical rail network, the Hamburg Port Railway (Hamburger Hafenbahn). Operating over 300 kilometers of specialized track and managing over 200 freight trains daily, this network connects container terminals such as Altenwerder (CTA), Tollerort (CTT), and Burchardkai (CTB) to the broader European hinterland.
In high-density freight corridors, crane runways, and urban transit operations (including the Hamburger Hochbahn U-Bahn and the S-Bahn Hamburg networks), rail track joints endure extreme cyclic stress, dynamic wheel loadings, and corrosive maritime environmental conditions. To guarantee track integrity, zero-deficiency safety, and uninterrupted operational cycles, aluminothermic (thermit) welding is the universally trusted methodology for creating Continuous Welded Rails (CWR).
As a seasoned OEM thermit welding portions manufacturer and supplier, RMTS delivers custom-formulated thermite powder blends, pre-formed refractory sand moulds, single-use crucibles, and precision track-servicing apparatus configured specifically to comply with European Standards (EN 14730-1 / EN 14730-2) and stringent German track construction specifications. Whether supporting standard 60E1/60E2 heavy-haul tracks, grooved tram rails, or massive A100/A120 quayside container crane rails, our metallurgical formulas ensure defect-free, homogeneous fusion joints with superior tensile strength and fatigue life.
High-tonnage freight corridors requiring durable thermite portions engineered for continuous wheel impact and maritime ambient humidity.
Specialized heavy-duty weld portions tailored for A75, A100, and A120 crane rails operating at container terminals.
Low-noise, smooth-running rail joints designed for rapid maintenance windows during overnight non-revenue operational hours.
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.

Whether you are looking for reliable thermit welding materials, expert training, or project support, RMTS is your trusted partner in achieving welding excellence.
High-precision chemical blending lines, automated sand mould pressing, and strict batch-by-batch spectroscopic testing ensure zero-defect thermite portions.
Pioneering advanced metallurgical compositions and thermal containment technologies tailored for high-speed, heavy-haul, and container logistics rails.
Our commitment to providing advanced thermit welding solutions that meet the specific demands of international railway operators and contractors.
Pre-lined, single-use refractory crucibles eliminate pre-heating delays and avoid cross-batch contamination. Engineered for fast, highly uniform molten steel release directly into the rail gap during rapid track maintenance windows.
Designed for heavy continuous track-laying and workshop depot environments. Multi-use crucibles equipped with replaceable refractory lining materials deliver superior economic efficiency and robust thermal shock resistance over repeated reaction cycles.
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, and ignitor are the essential consumables for aluminothermic welding: 1 weld = 1 set of consumables.
Accurate consumable logistics planning is vital to keep track maintenance and construction crews fully supplied without costly downtime on site.
Example: For a 10 km continuous track renewal project utilizing standard 12.5 m rail segments:
*RMTS supplies complete packaged kits including portion powder, matched 3-piece or 2-piece sand moulds, sealing paste/luting sand, self-tapping plugs, and ignition sticks for exact site deployment.
RMTS is a passionate and progressive aluminothermic welding manufacturing company delivering comprehensive engineering backing across Europe and international territories.
Aluminum thermite welding, also known as aluminothermic welding or thermit welding, is a specialized welding technique that utilizes an exothermic chemical reaction (reduction of iron oxide by aluminum powder) to generate intense heat (>2,400°C) for joining steel rail components seamlessly into continuous welded track.
Preparation Step 1: Ensure the rail ends to be welded are thoroughly clean, free from rust, oil, and moisture, and properly aligned with precision clamps. The standard gap size between two rails to be welded shall be strictly calibrated to 26 ± 2 mm before applying sand moulds.
Thermit welding materials will fail if exposed to moisture. All welding consumables—including thermite portions, sand moulds, crucible linings, and luting sand—must be rigorously kept away from moisture both during warehouse storage and across all on-site welding operations.
Thermit welding, also known as aluminothermic welding, requires careful handling and storage of its materials to ensure safety and optimal performance. Store in dry, well-ventilated, weather-sealed facilities on wooden pallets elevated above ground level.
We offer a wide range of thermit welding materials, such as welding kits, sand moulds, one shot crucibles, long life crucibles, luting sand, and ignitors, ensuring consistent metallurgical quality, homogeneous weld hardness, and reliable performance across heavy rail corridors.
Our dedicated engineering specialists provide tailored batch formulation, profile customization for European DIN/EN rails, and comprehensive welder certification programs to support track contractors operating in Hamburg and the wider DACH region.
Comprehensive aluminothermic portions, crucible accessories, rail shearing, tensioning, cutting, and grinding machinery serving industrial rail contractors in Hamburg.
