Key Applications of JIS 40N Rail
JIS 40kgN rail excels in heavy-duty scenarios, providing reliable support for equipment and transport systems requiring superior strength and stability.
Mineral Extraction Heavy Haul Routes
It forms a rugged foundation for large ore transport vehicles, withstanding constant movement and harsh underground conditions.
Port Container Handling Lines
It facilitates movement of container-loading machinery, adapting to outdoor humidity and variable weight stress in busy ports.
Factory Heavy Machinery Tracks
It enables smooth operation of industrial presses and large assembly-line equipment, maintaining stability under continuous heavy loads.
Heavy Crane Runway Systems
It supports high-capacity overhead cranes in industrial workshops, resisting deformation from repeated lifting and lateral forces.
Custom Solutions for Your Needs



- Custom Length Sizing with Precision Tools
Cut to exact lengths from 6m-24m (or custom sizes), fitting your facility’s layout with minimal waste. - Pre-Drilled Holes for Secure Fastening
Precision-drilled holes ensure perfect alignment with heavy-duty clips and bolts, streamlining on-site installation. - Corrosion-Resistant Coating Treatments
Zinc or epoxy coatings enhance durability in humid mines, coastal ports, or outdoor industrial environments. - Smooth End Machining & Beveling
Polished, beveled ends create tight joint connections, reducing vibration and extending service life in high-stress areas.
