JIS 37A Rail in Industrial Use Cases

JIS 37kg rail is tailored for heavy-duty operations, thriving in environments demanding superior strength and durability under constant heavy loads.

Mining Heavy Transport Routes

It supports large ore carts and mining locomotives, handling substantial payloads reliably in dusty, high-vibration underground conditions.

Factory Heavy Machinery Tracks

It enables smooth movement of industrial presses and assembly-line equipment, withstanding stress from bulky machinery in factories.

Port Crane Runway Systems

It forms stable tracks for gantry cranes, resisting bending from repeated lifting of shipping containers in busy port operations.

Logistics Hub Heavy Transport Lines

It withstands the weight of stacked cargo via rail-guided vehicles, reducing sagging in high-traffic distribution centers with frequent heavy loads.

Custom Solutions for Your JIS 37kg Rail Needs

We deliver tailored services to align the rail with your project’s unique demands, ensuring optimal fit and performance:

Custom Length Fabrication with High-Precision Tools
Cut to exact lengths from 6m to 24m (or beyond), matching your facility’s layout with minimal waste.
Pre-Drilled Holes for Seamless Fastener Fit
Precision-drilled holes ensure perfect alignment with heavy-duty rail clips and bolts, streamlining installation.
Corrosion-Resistant Coating Treatments
Protective layers (zinc or epoxy) enhance durability in humid mines, coastal ports, or outdoor industrial settings.
Smooth End Machining with Precision Beveling
Polished, beveled ends create tight joint connections, reducing vibration and extending service life in high-load areas.
