38kg Rail
Product Overview
Gloryrail offers a 38kg/m custom heavy rail, engineered for heavy-duty applications. Compliant with GB2585-2007 heavy rail standards, this rail can be customized to meet specific project requirements. With a theoretical weight of 38.73kg/m and adjustable lengths (6–24 meters), it is ideal for industrial railways, heavy freight lines, and specialized transit systems.
Key features
Heavy-Duty Design
Robust Cross-Section:
Rail height: 134mm ; base width: 114mm
Web thickness: 13mm; head width: 68mm.
Material Options:
U71Mn Steel (default): Tensile strength ≥880MPa, hardness ≥260HBW, ideal for heavy freight and high-speed applications.
Precision Manufacturing
Tolerances:
Length tolerance: ±10mm; cross-sectional dimensions controlled within ±0.8mm.
Bolt hole positioning accuracy: ≤0.5mm for seamless integration with heavy rail accessories.
Materials
U71Mn High-Strength Steel
Composition (wt%): C 0.65–0.77%, Mn 1.0–1.4%, Si 0.15–0.35%, P≤0.035%, S≤0.035%.
Advantages:
Pearlitic structure for high hardness (≥260HBW) and fatigue resistance.
Suitable for axle loads ≤35 tons.
Applications
Heavy Freight Railways: Mainline coal/iron ore transport (axle load 30–35 tons), reducing rail wear by 30% vs. standard heavy rails.
Mining Haul Roads: High-capacity conveyor systems and dump truck tracks in open-pit mines.
Industrial Heavy Rail: Steel mill hot metal transport and port quayside cranes.
Specialized Transit: High-speed freight lines and heavy-haul commuter rails.
Technical Advantages
Good Load Capacity
Supports 35-ton axle loads, ideal for heavy-duty freight and mining applications.
Custom Solutions
Tailored to project-specific requirements (e.g., corrosion resistance for coastal railways, heat resistance for metallurgical zones).
