Large-Diameter Structural Pipe
Large-Diameter Structural Pipe
Large-diameter structural steel pipes for columns, posts and load-bearing frames where high load capacity and buckling resistance are needed.
- Standard
- TS EN 10219 (cold-formed), TS EN 10210 (hot-finished)
- Steel grade
- S235JRH, S275J0H, S355J2H
- Size range
- Typically 114.3 mm OD and above
- Wall thickness
- Typically 3 – 10 mm, depending on diameter
Description
Large-diameter structural pipe is a circular hollow section used as a load-bearing member in steel structures. Because a round section offers equal bending strength in every direction and good buckling behaviour under compression, it is a natural choice for columns and posts.
It is used for building columns, canopy supports, sign and billboard posts, and the main posts of large gates. Diameter and wall thickness should be selected according to the project's structural calculations.
We keep certified large-diameter pipe on racks in our warehouse and load it onto vehicles by overhead crane. Alongside material supply, our steel application and contracting service can also support your project.
