ASCE 70 rail, commonly referred to as 70lb rail, is a heavy-duty American standard rail profile used in industrial track systems where loads are continuous and impact forces are part of daily operation. Compared with lighter ASCE rail sections, it delivers noticeably higher stiffness and structural stability, without creating unnecessary complexity during handling or installation.
Produced to ASTM A1 and ASCE specifications, ASCE 70 rail is rolled from 55Q carbon steel with controlled chemistry to ensure stable mechanical performance. The uniform cross-section and tight dimensional control support reliable alignment and long-term service, making this rail well suited for crane runways, steel mills, and mining transport lines that demand predictable performance over extended operating cycles.
ASCE 70 rail features a balanced profile that supports high wheel loads while maintaining alignment stability across long track runs. Custom dimensions or special rolling requirements can be provided upon request.

ASCE 70 rail is typically manufactured from 55Q high-carbon steel, selected for its strength, wear resistance, and fatigue performance under repetitive loading.
Material Characteristics
For projects requiring higher strength or special operating conditions, alternative steel grades can be customized based on application requirements.
