ASCE 40 Rail
Product Overview
The ASCE 40 medium-duty rail （Also called 40 lb rail）is a high-strength, corrosion-resistant steel rail designed for heavy-load applications in mining, port logistics, and temporary railway systems. Manufactured to strict ASTM A1 and AREMA standards, it balances durability with cost-effectiveness, making it ideal for scenarios requiring reliable performance.
Key features
Rail height: 88.9mm ; base width: 88.9mm
Web thickness: 9.9mm; head width: 47.6mm.
Material: 55Q Carbon Steel (Default):
Chemical Composition: C 0.52–0.60%, Mn 0.60–0.90%, P ≤0.04%, S ≤0.04% (ASTM A1)
Key Specifications:
Profile: Symmetrical wide-flange design (19.84kg/m)
Length:Standard: 6/24 m; custom lengths available upon request.
Lightweight Design for Easy Installation
19.84kg/m weight reduces transportation costs and simplifies manual handling.
Compatible with standard light rail fasteners (e.g., rail clamps, wood or concrete sleepers).
Cost-Effective Performance
55Q carbon steel offers reliable strength (tensile ≥685 MPa) for non-heavy-duty applications.
Precision Engineering
Straightness: ≤2 mm/m (ASTM A1 requirement), minimizing track alignment issues.
Applications
Mining & Quarrying
Narrow-gauge railways for underground ore transport .
Temporary haul roads for mobile equipment in open-pit mines.
Port & Logistics
Container handling systems (e.g., straddle carriers in Port).
Automated guided vehicle (AGV) rails in warehouse logistics.
Construction & Temporary Projects
Shoring and scaffolding support rails in civil engineering sites.
Event infrastructure (e.g., temporary tramways for large-scale exhibitions).
Agriculture & Forestry
Logging railways in forestry operations.
Farm tracks for equipment trailers and irrigation systems.
