Hi just a quick question does it state in any regulations that we can't use 3.2mm thickness scaffold tube if so could you please update me on this fact thanks guys.
 
3.2mm used to be the minimum thickness allowed under EN 12811. perhaps someone in design could confirm if this is still the case.
 
Higher quality S355 tubing (and 25% lighter than S255) with a diameter of 48.3mm and a wall thickness of 3.2mm has a yield strength of 355 N/mm2.

Temporary works engineers generally make the assumtion that S255 tubing will be used if a data sheet is not attached when using S355.

In short, S355 tubing with a wall thickness of 3.2mm is stronger in shear, tension and compression than standard S255 tubing with a wall thickness of 4.0mm.

how the feks that work out phil with it been thicker you would presume ti would be straonger why is this not the case any ideas
 
quailty of the steel basically
the s355 tube is a stronger compound therefore you can use less ie thinner wall
 
As stated the 3.2mm should be S355 (old grade 50c)
The 4.0mm is S275 (old grade 43C) but has been known to go as low as S235 (old grade 40c)

"Proper" Cuplok is 3.2mm grade 50c

But in answer to your question no there is nothing in the regulations to say you cannot use 3.2mm I think you will fing that Lyndon use nothing but 3.2mm.
