can anyone help with some sign fixing advise please?
Can anyone point me in the right direction please. Need to fit 2 large signs onto metal cladding. The signs are flat panel skybond to be fixed straight on to the cladding. What are they best fixings for this?
I’m off to B&Q this afternoon so any advice would be welcome as I haven’t got the foggiest idea what I’m looking for!!!! LOL 😳 -

tech screws and a tech bit for the gun to hold/screw the screws.
you will need open threaded tech screws for this type of material. close threads etc are for harder metals like steel posts etc
ill see if i can dig out where we buy from, think there is a few sources we use.b&q dont do them though…

A word of caution, not all cladding is made the same. It ranges in thickness & quality from 0.5mm to 0.7mm. Tec bolts can pull through single skin cladding quite easily yes i know people have for years used them & they will post all is well with their signs years on but tec bolts where originally designed to either secure 2 sheets together or secure the sheet on to a purling of up to 3mm thickness. Securing a composite board to the cladding alone with them is totally different, the board is light which is a plus point but wind can access the board from top & bottom & in some cases from each side depending on the board size. It does not take much to work these bolts loose & once one goes in a gust of wind they all will.
I prefer to use either Peel rivets of a 5mm diameter or Butterfly through bolts sometimes i’ll use these in conjunction with Tec bolts it just depends on the job, surface & whats behind the surface.As i say just a word of caution every job is different so don’t just presume Tec bolts are the answer every time when fitting to cladding

yes thats them. be sure to get the bit for the gun too… 1inch long full thread is fine for what your doing.

cheers, I’m off up to Bellshill then. 😀

The thread on those look to close ( or should I say fine) I would use a course thread allowing for more grip in thin cladding, or pop rivet is the best way

Actually you need two of those Phil cos you always drop the first in the deepest pile of autumn leaves and mud even if it is not directly below you (law of sod)….. :lol1:
Thinking on it you need three of those so you can put one in a logical place in case you lose others but then forget where that logical place was……..
