12kg Rail
Product Overview
As a specialized supplier in China’s steel rail materials sector, Gloryrail strictly complies with GB/T 11264-2012 Hot-Rolled Light Rails to deliver high-performance 12kg/m light rails globally. Manufactured via hot-rolling, this product combines high strength, fatigue resistance, and cost-efficiency, suitable for medium-load applications such as mining transportation, metallurgical production lines, port handling, and industrial rail systems. With standard lengths of 6–12 meters and support for customized processing, it ensures stable operation in complex environments.
Key features:
Precision Dimensions:With a standardized profile of 69.85mm (height) × 69.85mm (base width) × 38.1mm (head width) × 7.54mm (web thickness), the rail provides balanced load distribution and stability.Each 12-meter length theoretical weighs 12.2kg/m, designed for seamless integration into existing infrastructure.
Materials
Q235B Carbon Structural Steel
Composition: C 0.12–0.22%, Si ≤0.30%, Mn 0.30–0.70%, S ≤0.045%, P ≤0.045%.
Advantages: Excellent weldability and formability, ideal for mining, factory tracks, and temporary transport lines.
Cost-Effective: lower cost than 55Q, suitable for budget-sensitive projects.
Precision Dimensional Control
Adheres to GB/T 11264-2012 tolerance standards: rail height 69.85mm (±0.5mm), base width 69.85mm (±0.5mm), web thickness 7.54mm (±0.5mm), length tolerance ±6mm, ensuring precise compatibility with fishplates and fasteners.
Bolt hole positioning accuracy within ≤0.3mm, burr height ≤2mm, significantly improving on-site installation efficiency.
Applications
Mining Operations
As main underground transport tracks: Q235B for medium mines.
Metallurgy & Heavy Industry
Used in steel mill ladle transport tracks (heat-resistant) and rolling mill material conveyors.
Ports & Logistics
Fits medium-small port gantry and forklift tracks; lightweight design reduces terminal infrastructure load; galvanized products last 3 more years in coastal salt environments.
Urban Transit
Core material for low/medium-speed light rail systems (e.g., airport links, industrial park commuter rails), compatible with small-radius curves (minimum 30m) and frequent switch operations.
Specialized Scenarios
Temporary emergency tracks (post-disaster reconstruction) and military temporary，capable of withstanding short-term armored vehicle loads.
Technical Advantages
Enhanced Load Adaptability
40% higher load capacity than 8kg/m rails.
International Compatibility
Dimensions align with ISO 6501, JIS E1101, etc.; customizable accessories fit European (EN 13674) and North American (AREMA) systems, minimizing customer adaptation costs.
Long-Term Reliability
Service life: total lifecycle maintenance cost 20% lower than comparable products.
