Steel roofing panels 100mm insulated

[UKenGB]

Planning on using something like Kingspan panels for a workshop building, each panel about 5m long.

How bendable are they?

I realise they are pretty rigid, but how much can they actually bend over that length?

The problem is that the eaves 'plate' is possibly 10mm higher than the plane of the purlins which are at about 1.2m spacing. I doubt the panel will flex 10mm in 1.2m, so I'd have to pack up the nearest purlin but what about the next one, or the one beyond that?

I might not need 10mm, it may end up only 8 or even 6mm. Just trying to get some idea of what might be possible.

Anyone any experience of these panels and can give me some idea of how much they can flex?
