QU120 Rail
QU120 rail takes its name from the 120 mm head width and is the largest in the QU series. Conforming to YB/T 5055-2014 standards and often produced from U71Mn or 71MnK steel, it offers exceptional wear resistance and load capacity. Weighing 118.1 kg/m, QU120 is designed for ultra-heavy crane operations, especially in mining environments and large-scale container terminals where extreme load and durability performance are required.

QU120 Rail Material Grade
U71Mn is the commonly used steel grade for QU rails. Its key chemical and mechanical properties are listed below.
QU120 Rails Project Applications
Heavy Loads
Handles the heaviest loads in industrial rail systems. QU120 is chosen for extreme-duty cranes requiring unmatched strength in large-scale operations and harsh work settings.
Mining Cranes
Built for mining environments with high abrasion and dust. QU120 ensures stable crane function where material loads are massive and the rail system must resist fast wear.
Mega Ports
Supports high-frequency container loading at mega ports. The rail’s robust profile maintains track alignment under continuous impact and vibration from oversized container handling.
Rail Customization Options
Rail Bending
We offer custom hot or cold rail bending to match project layouts. Precise shaping ensures a perfect fit for curves. Curvature is tailored to drawing or site needs.
Drilling Services
Drilling is fully customized to your fastening system. We handle fishplate holes or web holes for forming bolts. Hole size and spacing are matched to your drawing.
Corrosion Protection
Rails can be treated with paint, zinc coating, or anti-rust oil. Each option suits different working environments. We select the best protection method for your usage scenario.
End & Joint Cutting
We cut angled ends, bevels, or special joints based on your assembly plan. Profiles support precise rail connections. Every cut is based on your drawing or on-site need.




Packaging & Delivery Assurance
- Standard export-grade packaging is adopted to protect all shipments during international transport. Each rail is fastened with steel straps and stabilized with wooden blocks inside the container. Waterproof materials can also be applied for additional moisture protection upon request.
- Accessories and structural components are packed in non-fumigated wooden crates and fixed in position to prevent shifting or impact damage en route.
- Our logistics team has substantial experience shipping to Africa, South America, and Central Asia, ensuring prompt and damage-free delivery to your destination.
