The 141RE rail, also known as 141lb rail, is an AREMA-standard profile developed for rail systems that operate under sustained high loads and demanding service conditions. It provides a well-balanced mix of load capacity and long-term track stability, situated between standard mainline rails and extra-heavy crane rails. For applications where axle loads, impact pressures, and alignment control must be consistent throughout long service cycles, this profile is frequently used. The 141RE rail, which is made of HH, IS, and SS steel grades, gives engineers a variety of material options while preserving uniform geometry and installation compatibility across rail infrastructure systems.
The 141RE rail follows the AREMA profile and features a balanced cross-section designed to handle high axle loads and repeated dynamic stress. Its dimensional design ensures stable wheel contact, reliable fastening performance, and long-term track alignment in heavy-duty railway and crane applications.

Length Options & Tolerances
For projects requiring non-standard lengths or tighter tolerances, customized production can be arranged based on engineering drawings or site conditions.
To meet different load conditions and service environments, 141RE rail is available in HH (Head Hardened), IS (Intermediate Strength), and SS (Standard Strength) steel grades. Each grade offers a distinct balance of hardness, wear resistance, and impact performance for heavy-duty railway and crane rail applications.
How to Choose the Right 141RE Rail Grade
Our technical team can assist in selecting the most suitable steel grade based on axle load, traffic density, environmental conditions, and service life expectations.

We supply 141RE rail with stable production capacity and stock support, ensuring reliable availability for both urgent and planned railway projects. Professional order coordination and export handling help reduce lead time and keep installations on schedule.
In addition to standard supply, we offer custom rail processing, including length cutting, drilling, bending, and head or surface treatment. These value-added services allow 141RE rail to be delivered ready for installation, minimizing on-site work and improving overall project efficiency.
For export shipments, 141RE rail is securely bundled with steel straps and handled by forklift or crane during container loading to ensure stability and safety. Standard rail lengths are typically loaded into 20ft or 40ft containers based on length and quantity, with proper weight distribution applied to meet shipping requirements.
Packaging can be adjusted according to project or destination needs, including wooden supports, moisture-proof wrapping, or reinforced protection for long-distance transport. Each shipment is prepared with clear marking and export documentation to help ensure smooth customs clearance and on-site unloading.
