Yeah do able, awkward if it's in middle of a sheet. If you've got a rebar tying gun it's possibly not worth the hassle. I'd give it a go if it was me.

What size are the sheets, if it's 4mx2m will be a job to handle in the press brake, might be easier in a folder.

For complex shapes isn't it quicker to send the drawing into the steel stockists
I don't know if they do whole sheets but definitely do single bars and it doesn't take long to learn to tie by hand
If not using the cable ties like things
Or a tieing gun is less than £50 a week

I bought both size max guns about 5 years ago when we were doing lots of 16mm x16mm at 100 c/c grids in the factory, been a game changer for us ever since.

I’d bet it’d be accurate enough for a Mog project, there will be more steel than concrete involved anyway!!!

What man as done, man can do, what never has,maybe
Tried with the duck........ no use can’t get a sharp bend where I need it also got to repeat it several times
Then welded a piece of channel to a 3m plate of steel and tried to press it with my blade (no use) grading beam(not tight enough)
This is the shape I want to achieve
I have 20 sheets of mesh 2.4x4.8 so want to use what I have
plus I do like a challenge

you'd need some pretty special tooling to achieve that in a press brake .....usual rule of thumb is you struggle to bend deeper than it is wide in the U if you follow me .....
could be done with swan neck tooling, but'd be sooome offset on the neck .....
who the hell came up with that shape Mog?????......
could bend two Ls and a Z and wire it together ... it's buried in conc anyway

as I need 9 bars running around the perimeter of the slab and thought this would keep all the bars spaced evenly and make them ridgid so easier to place and fix, might be a bit tricky to form though

A single u shape is possible form a 90 with blade/beam and bucket combo and then ig you have a beam or similar the height you want the two layers apart just fold it down over it. I guess if you needed to hold the beam you could weld a couple of lengths of box to it to sit the blade on from far enough back. Then just make another to lay on top. It's probably doable to fold back on itself if you could space everything apart etc but probs cost more in time than the mesh saving.I came up with it

How far apart do you want the layers and I'm guessing from you diagram they don't have to be connected?Tried with the duck........ no use can’t get a sharp bend where I need it also got to repeat it several times

bend a U and an L Mog .... wire the L in the UI came up with it

If you have the steel already and want to use it
And as I understand it the steel work connecting the 9 bars isn't as important/required in the curved form
Then why not cut the sheets and either tie to make a box if you have enough spare or use one of the spacer products available to stack 3 cut panels on top of each other
With some careful planning you could probably cut to get very little in the way of double bars running nxt to each other

I think that’s a cop out
if I can bend a U I can flip it over and do the same on the opposite side to form the shape I want
V8Druid

yes but remember .... doing it deeper than it is wide is a swan neck job .... my U is equal width/height and the L is the same height as the U ... job done and will have finished it by the time you've pee-ed about and got a quarter of it done in one pieceI think that’s a cop out

Or another solution bend one strand at a time few degrees at a time until u have the desired shape
On a more serious note we have a rebar bender that is a 5 foot bar with a plate on the end to make an f shape
If you had enough of these for each bar on the mesh just pull it round with a machine

even got it cut
just need a dry day to weld it up as the MIG in the scrapyard is not working so will have to use mine which means outside welding as need to bend the mesh to put in the floor to sit my shed on
