ASCE 50 Rail
Product Overview
ASCE 50 Rail (50 lb/yd) — a proven light-duty rail profile engineered for reliable, cost-effective service in mines, industrial plants, forestry tramways and temporary construction tracks. ASCE 50 is specified by its 50 lb/yd theoretical mass (24.855 kg/m) and features a symmetric profile (height = base width) that simplifies installation and ensures excellent stability for light-to-medium duty operations.
Key Points
Internationally recognized ASCE profile, widely compatible with existing ASCE accessories and fastenings.
Symmetric section (height = base width) for simplified installation and uniform load distribution.
Optimized for light and medium duty: lower transport and installation cost compared with heavy rail.
Available in standard and higher-grade steels ( 55Q, 700) and in corrosion-resistant treatments for harsh environments.
Factory quality control and traceable material certificates available for export shipments.
Mechanical & Material Performance
Hardness: Brinell ≥ 201 HB (typical; per agreed test plan)
Tensile / Yield / Elongation: To comply with ASTM / AREMA requirements (values detailed in technical datasheet)
Impact toughness: Supplied to meet light-rail operational safety requirements (Charpy V-notch where specified)
Non-destructive testing: Ultrasonic or magnetic particle inspection as contractually required

Typical Applications
Underground and open-pit mining tramways
Industrial plant internal rail systems for material handling
Forestry logging tramways and temporary extraction lines
Construction site temporary rails for heavy material movement (bridges, tunnels)
Ports & agriculture where lightweight, low-cost track solutions are needed
Installation & Maintenance Guidance
Recommended sleeper spacing: 600–800 mm (adjust to axle load and operating profile)
Minimum recommended curve radius: ≥ 15 m (dependent on vehicle wheelbase and speed)
Routine checks: rail head wear, fastening torque, alignment and rail end condition
For corrosive environments, select corrosion-resistant material or protective coating
