Custom corrugated sheet steel panels for home DIY project. Brake job anyone?

[Robin Hewitt]

or make a helpful suggestion?

First unhelpul suggestions :naughty:

Aren't you rather assuming an even temper throughout the sheet to stop it bending like a banana?

Folding it with a press brake looks a bit labour intensive and fraught.

Lining up for the next fold by pulling it back against the previous fold could be a bit cumulative error wise.

Now a suggestion...

It looks like it needs a custom machine to make it if you want to go commercial.

I'd suggest advancing the plate though a slot then pivoting two bending tools slightly behind the slot exit so one folds on the up stroke, one on the down.

The full 90 degrees would be tricky because there is more metal to spring back.

Lord only knows what shape it would come out, but it could be even with a bit of careful adjustment.

Cleverness would be required gripping it for the advance at sheets end.

This is purely off the top of my head so might be utter gibberish.
