46E2 Rail
Product Overview
46E2 rail (also called U33 rail) is engineered to deliver uncompromising performance in heavy-duty industrial and railway environments. Compliant with EN 13674-1 standards, this rail is manufactured from premium pearlitic steel grades (R200, R260, R260Mn, R350HT) to resist wear and fatigue. Its robust design and global compliance make it ideal for heavy-duty crane systems, mining railways and port logistics.
Key Features
Dimensions:
Weight: 46.27 kg/m (92.9 lb/yd)
Head Width: 62 mm | Rail Height: 145 mm | Base Width: 134 mm | Web Thickness: 15 mm

Material & Mechanical Properties
Standards: EN 13674-1 (rail geometry), ISO 9001:2015 (quality management)
Steel Grades:
R260 (260–300 HBW, ≥880 MPa tensile strength): Standard for mainline freight (axle loads up to 25 tons) and regional passenger lines.
R260Mn (enhanced Mn content, ≥900 MPa tensile strength): Optimized for high-wear environments (mining, ports).
R300HT (heat-treated, 300–340 HBW, ≥1080 MPa tensile strength): For ultra-heavy haul (30+ ton axles) and high-speed (≥200 km/h) applications.
Customization Services
Rail Processing: Pre-drilled bolt patterns (M20–M24), stress-relieved end machining, and mill-certified weld preparation.
Accessories:
Rail clips & fish plates & bolts for 46E2
Rail(rubber) pads (5–15 mm thickness) for vibration damping.
Applications
Industrial Cranes & Heavy Machinery
Supports overhead cranes and monorails in manufacturing facilities, handling dynamic loads with R350HT grades offering extended wear resistance .
Used in automated warehouses for AGV (automated guided vehicle) tracks, ensuring precision movement of heavy cargo .
Railway Systems
Ideal for light rail and heavy-haul freight networks.
Deployed in feeder lines for high-speed trains (e.g., connecting stations to TGV/ICE corridors), with R350HT grades supporting axle loads up to 30 tons .
Mining & Quarries
Resists deformation from uneven track beds and abrasive ore cart wheels in underground and open-pit mines .
R260Mn grade preferred for surface quarry rails, withstanding repetitive loading/unloading of gravel and stone .
Ports & Intermodal Terminals
Critical for container gantry cranes in hubs, with galvanized 46E2 rails resisting saltwater corrosion and repetitive stress from automated stacking systems .
Used in AGV (automated guided vehicle) rails for seamless integration with warehouse logistics, ensuring precision movement of heavy cargo .
Construction & Heavy-Duty Infrastructure
Temporary rail systems for tower cranes and precast concrete yards, ensuring safe and efficient material handling.
Heat-resistant R350HT grade maintains structural integrity in steel mill hot zones.
