Crane booms are the backbone of lifting operations. They require structural components that can withstand extreme forces, long working hours, and challenging environments. This is why selecting the right steel tube matters.
What Makes a Steel Tube Suitable for Crane Booms?
Crane booms operate under high bending, compressive, and dynamic loads. The steel tubes used must offer a precise combination of strength, toughness, and dimensional accuracy to ensure long-term performance and safety.

Key Performance Requirements:
- High strength – To support heavy loads without failure
- Fatigue resistance – For repeated extension and retraction
- Impact resistance – To absorb sudden shocks
- Dimensional precision – For accurate boom assembly
- Weldability – For secure, easy fabrication
Recommended Grades and Sizes
We offer a full range of steel grades to suit different structural needs:
| Strength Level | Steel Grades | Application Highlights |
|---|---|---|
| Medium Strength | Q345D, S355J2H | Cost-effective, general structure |
| High Strength | Q460D, S460NLH | Main booms, critical load areas |
| Ultra High Strength | Q690D, STE690, YGS770–960BJ | Heavy-duty cranes, fatigue-critical |
Size Range:
- Round tubes: 48×3 mm to 508×30 mm
- Square tubes: 30×30×3 mm to 400×400×20 mm
Seamless or Welded?
Both are suitable, but the choice depends on the performance demand:
- Seamless steel tubes: Ideal for ultra-heavy duty or fatigue-sensitive areas
- Precision welded + stress-relieved tubes: Ideal for optimized cost and performance
We also support large-diameter thin-wall welded tubes, with excellent dimensional tolerance.
