Attaching Large Signs to Steel Wall Buildings
Attaching Large Signs to Steel Wall Buildings
(OP)
Any recomendations for attaching large signs to the wall of corrugated wall steel panel buildings. Interested in simple but safe techniques which will pass muster with passing building codes and wind loads.
Seems as if corrugated panels ( some as thin as 26 ga ) will generally not have the screw holding strength unless the thickness approaches 16 ga or so.
Any thoughts or recomendations ?

But if it is like most steel buildings - there may be very little "extra" for carrying any superimposed loads. So double check them. And girts are really not designed to carry much vertical load - usually just wind.
If the walls can already carry the wind load - how will your sign add any more wind load??

I once put an open web joist in alongside the girt to support the load, using the girt for lateral stability.

Timing has a lot to do with the outcome of a rain dance.

Girts not anywhere close to customers location for sign. Sign wraps all around perimeter of building. Beams are 20 ft. apart.
Negative wind loads have potential for pulling sign from wall if poorly or improperly attached. Not comfortable with Tek screws or rivets.

Looks like you will have to design some type of supports to be placed probably internally and hung off the frames. Then bolt through. Not going to be cheap.

1) we have not seen the building (there could be things that you have missed)
2) we dont know the full details regarding the sign.
3) We dontknow the location.
4) we have not carried out any design calculations to verify our design.
Many of these small signs are much more complicated than they look. You may also need a permit for this sign.

How 'bout just an independent sign structure just outside of the wall?
RE: Attaching Large Signs to Steel Wall Buildings
refer to the attached sheet for an example...if the building does not have them already - you just need to place them inside between the W-members (columns) where you need them and attach accordingly with Tek-screws.
