Adding cross bracing to shed

[diyshed]

Bought a kit shed which I'm about to start to put up.. Forgot to add in cross bracing when ordering up shed. She's is 47ft x 40ft.

I'm thinking of using angle irons as cross bracing. What thickness of these is the norm? 6mm. Is cross bracing on the sides an overkill or will the roof do?

If the company that made it for you is legit it should already have cross bracing in roof and at one end on sides!

The little diagonals from the beams to the purlins are pretty important to.

Should have thought they would have come as standard, is the shed CE marked or whatever system is used now . Not sure its legal if it's not and insurance might be difficult

None of the older sheds here have them or cross bracing in the roof but they’re still standing 50/60 odd years later

If they are being added for structural strength I would prefer the tube type to angle iron.

Foot of Snow on the roof and you will wish you had them.
Peanuts extra £ssss.

Older sheds have lateral stability in some other way - usually there's some form of portalisation in each direction. It can be quite subtle, some of ours have quite decorative knee braces which provide the longitudinal stability.

Yes you need bracing in the walls and in the roof. I should call the supplier and you need to think about connection/bolt sizing as well.

Got a grand new shed don’t have them little braces obviously have crossed braces in one bay and roof

Nope, our oldest sheds have no form of bracing but to be fair, they’re made of larger rsj’s than some of the newer ones that have such bracing, and at 50 plus years old and still standing, I’m not in the least bit worried about the lack of bracing

Post a picture and I'll tell you how it's done.

I'm not suggesting they're any weaker but there's usually some design detail that stabilises them.

Like multiple rivets/spout bolts holding all the way around each sheet.

If you are doing a x-bracing then yes angle iron will work but so will flat plate. Something like 100x10mm flat, bolt it to the inside flange if you cant weld tabs on.

Suppose the question that should be asked has the design been approved by a Structural Engineer?

Clearly not if it has no bracing....
