steel rails
Mining and resource transport railways operate under some of the harshest conditions for rail materials. Dust, moisture, abrasive particles, and continuous loading place high demands on rail strength and wear resistance. GB Standard 30kg light steel rails are widely used in such environments because they provide a practical balance between durability and installation efficiency.
A 30kg rail offers sufficient section modulus to resist bending and fatigue while remaining easier to transport and install than heavier railway rails.
Key Features
High Strength and Wear Resistance: The 30kg rail is made of high-quality carbon steel or manganese steel, making it suitable for high-frequency operation scenarios.
Standardized Section Design: With precise dimensions and high installation matching degree, it facilitates rail butt joint.
Supporting Supplies Available: GNEE STEEL can provide a full set of accessories such as fishplates, bolts and nuts, rail pads, and rail clips.
Flexible Application: Suitable for various track systems such as light rails, factory areas, mines, and ports.

Mining Application Scenarios
| Mining Environment | Typical Rail Use |
|---|---|
| Open-pit Mines | Material haulage lines |
| Underground Mines | Narrow-gauge rail transport |
| Quarry Operations | Aggregate and stone movement |
In underground mining systems, space constraints often limit rail size, making 30kg rails a common choice.
Mechanical Properties Relevant to Mining Applications
| Property | Typical Value |
|---|---|
| Tensile Strength | ≥700 MPa |
| Yield Strength | ≥420 MPa |
| Hardness | HB 250–320 |
| Elongation | ≥10% |
These properties help maintain track geometry and reduce wear-related failures under repeated loading.
