Ductile N Grade Mesh

Following on from the thread above - it seems now ductile mesh can be readily made.

Are people starting to use this? Never liked L grade mesh in suspended slabs due to the loss of ductility.

Reason I started looking, is because I have a 500-300 thick transfer plate and am looking for a typical top mat to satisfy the WH&S guidelines of a 200x200 grid for the top layer on slabs thicker than 300mm.

Go with the mesh or the mat of N12-200? Keeping in mind they are now both ductile.

I don't know the answer to your question but I'm curious about the 200x200 grid. Is that to keep workers from falling through?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Indeed.

And 300mm is roughly the height of concreting gum boots, any higher and concrete would spill into your boots. This could be a tall tale from my boss though.

Anyone?

Trenno,

Yes, apparently one supplier in Australia has N class mesh from what I have ben told. You can get Class E in NZ!

If you are simply using it to provide the 200*200 for WH&S and it is not being relied on for ultimate strength, then there would be no problem with using Class L mesh.

Not sure about the gumboots but 200*200 is much safer to walk on than 300*300, much easier on the shins for us clumsy people.
