24kg Mine Track
Product overview
The 24kg mine track combines load capacity with lightweight design to deliver a versatile, cost-effective rail for a wide range of uses. With optimized cross-section and proven mechanical properties, it’s ideal for mining, industrial production, tourist lines, and temporary works. We keep both Q235B and 55Q grades in stock to meet light-load and high-wear requirements.
Key specifications
Rail height: 107 mm
Base width: 92 mm
Head width: 51 mm
Web thickness: 10.9 mm
Nominal weight: 24.46 kg/m
Standard lengths: 6 m, 9 m, 12 m (custom cutting available up to 24 m)
Material options
Q235B (low-carbon structural steel)
Yield strength ≥ 235 MPa; tensile 375–460 MPa; elongation ≥ 24%
Excellent weldability and toughness; easy to form and weld. Best for static or light dynamic loads such as factory temporary lines and tourist tracks. High cost-performance ratio.
55Q (medium-carbon structural steel)
Approx. 0.55% C; tensile ≥ 685 MPa; Hardness HBW≥197
~40% better wear resistance vs Q235B and superior impact resistance. Suited for harsh, dusty, wet environments and frequent start/stop operations — e.g., underground haulage and heavy workshop tracks.

Quality control & testing
Process control: steel billet → heating & rolling → cut to length → straightening → surface rust protection → inspection & storage.
Appearance inspection: no cracks, laps, folds, or heavy inclusions; surface rust area ≤ 5%.
Dimensional tolerances: cross-section ±0.5 mm; length ±20 mm — compliant with GB/T 2585.
Mechanical & NDT: 100% tensile and bending tests (bend angle ≥ 45°); ultrasonic flaw detection available for critical applications.
Standards & certifications: complies with GB/T 2585-2007. Export items can be supplied with JIS, ASTM, or BS certificates on request.
Inventory & delivery assurance
3,500 tonnes on hand, covering Q235B and 55Q in 6–12 m lengths for immediate pickup.
Fast response: custom cutting and anti-rust treatments (oil coating / wrapped) available; standard orders dispatched within 72 hours. Emergency projects may be handled via a green channel.
Quality control: stock is regularly rotated and inspected for surface corrosion and dimensional accuracy to ensure deliveries meet specifications.
Typical applications
Mining
Underground auxiliary transport for small/medium mine cars (axle load ≤ 10 t). 55Q is recommended for wet, dusty conditions and rock impact.
Short open-pit links between pits, crushers, and sorting yards — easy to lay and reconfigure as mining progresses.
In-plant tracks at concentrators and processing areas — Q235B is weld-friendly for complex layouts.
Industrial & Logistics
Workshop runways for light overhead cranes (5–15 t) and shop cranes; 55Q reduces wheel/rail wear and maintenance.
AGV and automated transfer rails — rail gauge accuracy controlled within ±2 mm for smooth operation.
Warehouse transfer lines and forklift guide rails — Q235B reduces floor load for dense racking.
Tourism & Temporary Works
Scenic tramways, visitor lines, and temporary track installations — quick to install and cost-effective.
Installation & maintenance
Installation methods
Ballasted track: fishplates + bolts, sleeper spacing 600–800 mm — suitable for mines and temporary outdoor lines.
Slab track (no-ballast): elastic fastenings directly fixed to concrete — faster installation and lower maintenance for factories and tourist lines.
Maintenance tips
Monthly checks for gauge deviation (allowance ±2 mm) and loose fastenings; quarterly wear measurements (head wear ≤ 5 mm, side wear ≤ 10 mm considered normal).
Lubrication recommended quarterly for 55Q head surfaces in high-wear applications; outdoor tracks should be kept clear of debris and standing water.
Replace or tighten components promptly when local wear or fastening issues are found.
