A steel rail is a load-bearing track element that ensures precise wheel guidance and stable motion by combining optimized cross-sectional geometry with high-strength steel materials. Its performance directly affects ride quality and structural lifespan of the track. GNEE RAILWAY RAILWAY supplies full-standard rails under GB, UIC, DIN536, JIS, AS1085, BS11, and AREMA/ASCE systems, including light rail, heavy rail, and crane rail categories such as QU and DIN A-series, supported by services like customized production, surface protection, and installation consulting.
What are ASCE Rail Dimensions?
ASCE rail specifications are typically named according to their weight per yard (pounds). This standard covers a range of specifications from light to medium-duty Tee rails, with major models including ASCE 25, ASCE 30, ASCE 40, ASCE 45, ASCE 60, ASCE 80, and ASCE 85. For example, ASCE 25 refers to rails weighing 25 pounds per yard; ASCE 60 refers to rails weighing 60 pounds per yard. GNEE RAILWAY RAILWAY can supply ASCE rails in all sizes for various applications.

|---|---|---|---|---|---|---|---|

| ASCE 85 | 65.09 | 131.76 | 131.76 | 14.29 | 42.17 | 900A/1100 | 12-25 |
What is the material of ASCE Rail?
ASCE Rails (American Society of Civil Engineers sections) are made from high-quality, heavy-duty steel, typically medium carbon-manganese steel, engineered for exceptional strength, hardness, and wear resistance to handle heavy loads from cranes and industrial transport. Key elements like carbon, manganese, silicon, and sometimes nickel, chromium, or copper are added to the iron to achieve specific performance requirements, with grades like 55Q, Q235B, or U71Mn common for different applications.

What is the difference between ASCE Rail and GB Steel Rail?
ASCE rails (American Society of Civil Engineers) and GB rails (Chinese National Standards) are both steel rail types, but differ in standardization, naming conventions (lbs/yard vs. kg/meter), common applications (ASCE for light industrial/cranes vs. GB for varied use), and specifications, though they can have equivalent weights (e.g., ASCE 30lb ≈ GB 15kg/m), with ASCE focusing on weight-per-yard for cranes and GB using metric for broader rail systems.
Key Differences
Standards & Naming:
- ASCE Rail: Defined by ASCE, named by weight per yard (e.g., ASCE 85 for 85 lbs/yard).
- GB Steel Rail: Defined by Chinese National Standards, named by weight per meter (e.g., 60kg/m).
| Classification | Height(mm) | Head (mm) | Bottom (mm) | Thick(mm) | Weight (kg/m) | |
| Heavy Rail | 38 KG/M | 134 | 68 | 114 | 13 | 38.733 |
| 43 KG/M | 140 | 70 | 114 | 14.5 | 44.653 | |
| 45 KG/M | 145 | 67 | 126 | 14.5 | 45.546 | |
| 50 KG/M | 152 | 70 | 132 | 15.5 | 51.514 | |
| 60 KG/M | 176 | 73 | 150 | 16.5 | 60.64 | |
Primary Use:
- ASCE: Often used for lighter applications like crane rails in factories, warehouses, and mining, designed for smooth, heavy loads.
- GB: Covers a wider range, from light industrial (e.g., 12kg/m) to heavier mainline railway applications (e.g., 43kg/m, 60kg/m).
Cross-Sectional Design:
- ASCE: Has specific proportions (head, web, foot) and a flat bottom, with height often equaling base width for lighter types.
- GB: Varies significantly by weight; heavier GB rails have different profiles for mainlines, while light GB rails suit industrial use.
Material Grades:
- ASCE: Materials like Q235B, 55Q (high-carbon), U71Mn alloy steel are common.
- GB: Also uses Q235B, 55Q, U75V (U75V), etc., but the overall material specifications align with Chinese standards.
