30kg Rail
Product Overview
Gloryrail presents the 30kg/m light rail, rigorously engineered to meet GB/T 11264-2012 Hot-Rolled Light Rails, offering superior performance for industrial. With a theoretical weight of 30.1kg/m and customizable lengths (6–24 meters), it excels in medium/heavy-load environments such as mine main haulage roads, port container crane tracks, metallurgical zone.
Key Features
GB Standard Compliance & Precision Engineering
Dimensional Accuracy:
Rail height: 107.95mm (±0.5mm); base width: 107.95mm (±0.5mm)
Web thickness: 12.3mm (±0.5mm); length tolerance: ±6mm
Bolt hole positioning error ≤0.3mm, burr height ≤2mm for seamless integration with standard accessories (fishplates, fasteners).
Surface Quality: Defect-free hot-rolled surface with allowable web scratches ≤0.75mm deep, ensuring rapid on-site installation and compliance with international transport standards.
Material Performance
Q235B Carbon Steel (Standard)
Tensile strength: 375–460MPa; yield strength ≥235MPa
Cost-effective with excellent weldability for on-site modifications and extensions.
55Q Special Steel (Custom Option)
Tensile strength ≥685MPa; hardness ≥197HBW
Applications
Mining Industry
Q235B: Primary transport in coal/metal mines for 22-ton side-dump cars, reducing track replacement frequency by 30% vs. lower-spec rails.
55Q: High-abrasion environments (e.g., iron ore pellet transport), extending service life under 25-ton axle loads.
Ports & Logistics
Rubber-tired gantry crane (RTG) tracks in major container terminals.
Heavy-duty forklift routes in logistics hubs, minimizing deformation from frequent 90° turns and start-stop operations.
Metallurgy & Heavy Industry
Steel mill ladle transport tracks in high-temperature zones.
Technical Advantages
Heavy-Duty Load Capacity
Supports 25-ton axle loads (30% higher than 24kg/m rails), covering 95% of industrial Medium-transport and urban transit requirements.
Global Compatibility
Dimensions align with ISO 6501, UIC 54, and JIS E1101, enabling seamless integration with international rail systems via custom fishplates and fasteners.
