American Crane Rails (ASTM standard)
American crane rails are widely adopted in industrial settings across North and South America, especially for overhead cranes and material handling systems. Designed under ASTM A759, CR rails come in sizes ranging from 104 to 175 lbs per yard, offering consistent dimensions with nearly equal base and height.
This structural balance supports stable installation and long-term durability. With multiple steel grades available, these rails meet strict metallurgical standards to ensure excellent load capacity and reduced wear under heavy-duty use.

Material
American crane rails are typically made from U71Mn steel, which meets the chemical composition requirements of ASTM A759. This high-strength manganese steel is well-suited for frequent and heavy-duty crane operations, offering excellent durability and resistance to wear. The choice of steel grade varies based on rail size and loading conditions to ensure optimal performance. For projects with specific mechanical or operational demands, higher-strength steel options are also available upon request, allowing for greater customization and enhanced load-bearing capacity.
- U71Mn steel
- ASTM A759 compliant
- Suitable for high-load crane systems
Manufacturing
All ASTM crane rails are produced using a hot rolling process to ensure precise dimensions and uniform internal structure. This method guarantees rail consistency and compliance with ASTM A759 standards, making them suitable for heavy-duty crane systems.
Lengths are customizable (typically 12–24 meters), with optional machining services including drilling, cutting, and end-face welding. For extended durability in demanding environments, surface treatments such as sandblasting, painting, or galvanizing are also available.
