ASCE 40 rail is a high-strength, light-duty steel track manufactured under American Society of Civil Engineers (ASCE) standards. The “40” denotes the weight per yard, i.e. 40 lbs/yd. Known also as 40 lb rail or Rail ASCE 40, it is widely applied in medium-load and medium-speed railway systems as well as crane rail applications. ASCE 40 rail offers excellent durability and reliability, making it a popular choice for various railway infrastructures.
The ASCE 40 rail complies with ASTM standards, with precise dimensions designed for consistent compatibility in railway projects. Below are the detailed specifications, steel grades, and mass per meter for ASCE 40 rail:
| Type of Rail | Standard | Dimensions mm | Steel Grade | Mass M | |||
| Height | Base Width | Head Width | Web Thickness | kg/m | |||
| ASCE 40 RAIL | ASTM | 88,90 | 88,90 | 47,60 | 9,9 | Q235B, 55Q | 19,84 |
