18kg Mine Track
18 kg mining rail (18 kg/m) — hot-rolled light rail optimized for mid-duty load scenarios. Available as 18kg mine track / 35 lb/yd mine rail. Custom lengths, material options (Q235B, 55Q,), surface treatments and one-stop accessory supply. Third-party inspection available.
Product Overview
The 18 kg rail (nominal 18 kg/m, theoretical weight ≈ 18.06 kg/m), commonly referred to as 18kg mine track or 18 kg mining rail, is a hot-rolled light rail designed for mid-duty applications that require a balance of load capacity and installation flexibility. Engineered with a symmetric I-section and precision hot-rolling, this profile is widely used for mainline mine haulage, industrial heavy-load logistics, port equipment tracks, and other environments with clear load and wear requirements.
This product can be supplied to meet domestic standard GB/T 11264-2012 and can be manufactured and documented in accordance with common international standards (ASTM / EN) for export. In markets using Imperial units, the profile is often referenced alongside equivalents such as 35 lb/yd mine rail.

Typical Applications
Main mine haulage: Primary tracks for surface or underground ore transport — specify appropriate corrosion and wear protection for harsh mine environments. (Related Imperial reference: 35 lb/yd mine rail.)
Industrial heavy logistics: Plant rail systems, track-guided handling equipment, and material transfer routes in shipyards, steelworks and heavy fabrication facilities.
Ports & specialized equipment: Tracks for port cranes, mobile handling systems and auxiliary rails in metallurgical areas — galvanizing and specialized coatings recommended for marine or corrosive environments.
Temporary construction & forestry: Reusable temporary track for material movement on large projects; easy to assemble and remove for site reuse.
Typical Technical
Materials available: Q235B (carbon steel), 55Q (higher-grade carbon steel)
Mechanical properties: depend on the chosen material grade and heat treatment — required mechanical test results will be supplied in mill certificates or test reports with each shipment.
Standard lengths: common cuts 6 m / 9 m / 12 m; custom lengths typically supported from 3–18 m (longer or special sizes subject to production scheduling)
Standards: GB/T 11264-2012; export configurations can be aligned with ASTM / EN upon request (Imperial equivalent reference: 35 lb/yd mine rail)
Surface treatments: as-rolled, anti-rust coating, hot-dip galvanizing, cold galvanizing (selection recommended by operating environment)
Inspection & documentation: mill certificates, factory inspection reports, and third-party inspection (e.g., SGS, BV) available per agreement
Key Advantages
Optimized for mid-duty mine and industrial use: The 18 kg profile (often specified as 18kg mine track) provides enhanced section strength compared with lighter profiles while maintaining manageable handling and installation demands.
Material flexibility to suit site conditions: Standard Q235B offers good weldability; 55Q improves wear resistance for high-cycle applications; U71Mn is available where higher toughness and wear resistance are required.
Engineered geometry for reliable operation: Symmetric I-section and optimized head profile improve wheel contact distribution and reduce localized stress, contributing to smoother operation and longer service life.
Robust manufacturing & QA: Precision hot-rolling and in-process inspections ensure consistent dimensions and surface condition; full documentation supports procurement QA/QC.
One-stop supply and processing: Length cutting, drilling, special profiling and matched accessories (fishplates, bolts, rail clips, sleepers) are available to simplify project logistics.

FAQs
Q:Is this rail available to international standards?
A:es — while domestic production follows GB/T 11264-2012, we can supply export configurations and documentation aligned with ASTM or EN standards. This product is commonly cross-referenced in Imperial units as 35 lb/yd mine rail.
Q:What surface treatment is recommended for coastal or port sites?
A:For marine or highly corrosive environments we recommend hot-dip galvanizing or a robust multi-coat anti-corrosion system. We can provide a recommendation based on specific site exposure.
Q:Can you arrange third-party inspection?
A:Yes. Third-party inspection (e.g., SGS, BV) can be arranged per contract.
