Descriptions of JIS 15KG Rail
This rail is widely used in mining transport lines, industrial track systems, temporary construction rails, warehouse logistics, and light sightseeing railways.
Its lightweight yet durable structure makes it ideal for flexible layouts, including small-radius curves and tracks that require frequent relocation.
To meet diverse operational environments, we offer multiple steel grades (50Q, U71Mn, or customized) and optional surface treatments such as painting, hot-dip galvanizing, or anti-rust coatings—ensuring optimal performance in both indoor and outdoor settings, even under corrosive or high-moisture conditions.
Key Features and Advantages:
Interchangeable with GB 12kg Rail
The JIS 12kg rail shares the same dimensional profile as the GB 12kg rail, including height, base width, head width, and unit weight.
This means it can be directly installed using the same rail fasteners, fishplates, and track accessories without modification.
Advantages of Compatibility:
- Flexible Procurement – Source from either JIS or GB standard suppliers based on price and availability.
- Easy Replacement – Simplifies maintenance and reduces downtime in mixed-standard track systems.
- Global Adaptability – Suitable for projects in regions where either standard is accepted.
⚠ Note: For heavy-duty or precision applications, we recommend verifying material grade and tolerance requirements to ensure full compliance with your project specifications.
Fully compatible with GB 12kg rails, allowing interchangeable use with existing track systems and accessories.
Lightweight & Easy to Install
Only 12.2 kg/m, making handling, transportation, and installation quick and efficient.
Ideal for temporary tracks, small-radius curves, and frequently relocated rail systems.

JIS Standard 12KG Rail Material Strength
Application of JIS 12KG Rails
The JIS 12kg rail combines lightweight design, flexibility, and durability, making it ideal for a wide range of light-duty rail systems. Whether in mining transport, construction projects, warehouse logistics, or agricultural and sightseeing railways, it provides reliable load-bearing capacity and easy installation. Below are the main application scenarios and their key advantages to help you quickly identify the suitable use cases.
Factory Transport & Material Handling Tracks
In industrial automation, the rail is used for assembly line tracks, material shuttles, and guided transfer lines, thanks to its small footprint and flexible routing within constrained factory layouts.
Light-Duty Crane Rail Systems
JIS 12kg rail is widely used in light-duty gantry cranes, single-girder cranes, and trolley systems. It is ideal for handling moderate loads in workshops, warehouses, and dockside environments where reliable movement and precision alignment are essential.
With our ready-to-ship stock and fast logistics, GloryCrane helps contractors keep projects on schedule.
Mining & Tunnel Narrow-Gauge Rail Systems
The JIS 12kg rail is commonly applied in mining haulage systems, tunnel construction tracks, and underground rail lines, where compact size and ease of installation are critical.
Warehouse Sliding Systems & Storage Rail Tracks
Used in logistics handling lines and ground-level sliding tracks, the JIS 12kg steel rail supports automated guided carts (AGVs) or manual trolleys for fast and smooth transport within storage and distribution centers.
Typical uses: Track for warehouse trolleys; AGV and automated transfer rails; Industrial material handling lanes
Complete Accessories for Mining Rail Systems – Enhance Performance & Safety
As a professional supplier of mining rail, GloryCrane not only provides high-quality light steel rails but also a full range of compatible installation accessories, ensuring safe and efficient operation of the entire rail system. All accessories undergo strict quality control to perfectly match rails, enabling “one-stop procurement + worry-free installation.”
Fish Plates(Rail Joint Bar) and Bolts: Fish plates serve to connect steel rails and distribute loads, ensuring track stability. Hole patterns can match standard JIS 50N steel rail profiles or be customized. High-strength bolts (grade 8.8 or 10.9) ensure tight connection.
Rail Clips: GloryCrane can provide rail clip models suitable for JIS 50N rails under different construction requirements: Wjk-model, welded rail clips, bolted rail clips, etc.
Rubber Pads: Rubber baseplates are used beneath the rails to absorb vibration and shock, helping reduce noise and extend track life. GloryCrane offer rubber matting for JIS 15kg steel rail bottoms, with a regular thickness of 510mm, made of highly elastic black natural rubber material, which can be customised to the size of the rail bottom.
Rail Soleplates: The base plate, also known as the sole plate, is an optional but important accessory used beneath the rail to provide enhanced stability and load distribution. They are especially useful when the rail is installed on concrete floors or steel beams, helping to reduce vibration, protect the substructure, and extend the life of both the rail and the foundation. Custom drilling and surface treatments are available to meet specific installation requirements. When combined with rail clips or anchor bolts, base plates offer a complete and reliable track fastening solution.
Alumothermic Welding kits for Rails: GloryCrane offers a full set of alumothermic welding equipment for crane rail track installation. Our solution uses an aluminum – iron oxide exothermic reaction to form high – strength, fatigue – resistant joints. With no need for complex power setups, it enables rapid on – site installation, making it a preferred choice for heavy – duty crane rails.
Anchor Bolts & Embedded Parts: Anchor bolts and embedded components are essential for securing the rail system to concrete foundations. Available as expansion bolts, chemical anchors, or pre-embedded steel channels for heavy-duty crane track installations.
Optional Components: U-shaped rail clips (for track fixing); Rail end caps (for corrosion protection); Custom fishplates with drilled holes
