8kg Steel Rail — 8kg Mining Rail / 16lb Mine Rail
Compact · Durable · Cost-effective — Ideal for short-haul, low-load industrial, mining and tourist track applications.
Product Overview
The 8kg steel rail (commonly called 8kg/m or 16lb mine rail) is a light-rail profile engineered for low-load, short-distance track systems. Optimized for small mine cars, industrial trolleys, theme-park trains and temporary construction tracks, it combines proven Q235B material performance with precision rolling and strict quality control — delivering a low-cost, easy-install rail solution for projects that do not require heavy-rail capacity.
Typical Applications
Underground & surface small-scale mining tracks (short haul).
Factory internal transport lines and material handling trolleys.
Theme parks & scenic railways for small tourist trains.
Temporary construction & municipal transport tracks.
Warehousing, agricultural and specialized light rail installations.

Core Advantages
Lightweight & low logistics cost: Up to ~30% lower transport cost vs heavy rail — simpler handling and no heavy lifting equipment required.
Easy installation: Tight section tolerances (±0.5 mm) for fast alignment with sleepers and joinery.
Cost-effective lifecycle: Designed for low-maintenance environments — expected service life 5–8 years in normal conditions with routine upkeep.
Versatile applications: Mining, factory internal conveyors, theme parks, temporary construction tracks, agricultural rails.
Customizable: Lengths, surface treatment and packaging tailored per order.
Quality Assurance & Testing
Raw material control: Q235B certified by supplier; mill test certificates issued for each batch.
Production monitoring: Key rolling parameters (temperature, pressure) recorded; dimensional inspections at defined stages.
Finished inspection: Dimensional check, mechanical testing and surface quality inspection; conformance report issued with shipment.
After-sales: 24/7 technical support; verified non-conforming policy with return/replacement upon confirmed defect.

FAQs
Q:Is 8kg rail suitable for underground mine haulage?
A:Yes — for small, short-distance underground haulage using light mine cars. For heavy loads or long-distance haulage, consider heavier profiles.
Q:What is the actual weight tolerance?
A:Theoretical weight is 7.7 kg/m with an allowed manufacturing tolerance of ±5%.
Q: Do you provide certificates?
A:Yes — mill test reports (MTR), dimensional inspection and testing reports are provided per shipment.
