Scaffolding steel pipe wall thickness standards: There are generally two types, one with an outer diameter of 48mm and a wall thickness of 3.5mm; the other with an outer diameter of 51mm and a wall thickness of 3mm; depending on its location and function, it can be divided into vertical poles and horizontal poles sweeping pole, etc.

Scaffolding is a commonly used temporary support structure in construction. Its safety and stability are crucial to construction quality and personnel safety. As the main load-bearing component, the steel pipes in the scaffolding have very strict quality and specification requirements.
For the wall thickness of steel pipes used in scaffolding, the specification requires at least 3.5mm. The thicker the wall thickness of the steel pipe used for scaffolding, the flexural strength will increase accordingly, which is very important for the overall stability of the scaffolding. In addition, depending on the height of the scaffolding, the wall thickness of the steel pipe is also adjusted accordingly. Generally speaking, if the height of the scaffold is less than 20m, the steel pipe selected should not be less than 3.5mm; if the height is more than 20m, the steel pipe should not be less than 4.0mm.
