corrugated building how to fix signs !!

[John Childs]

You could just use white topped self tappers but if you don’t want the panels to warp you need a frame of some kind. Panatrim is the cheapest way.

If the panels are really small, and you want to fix direct, drill oversized holes in the foamex and don’t tighten the screws too much so that there is a bit of slop to take up expansion.

For direct fixing I always use dibond so that the expansion problem goes away.

cheers john ill take that on board

I hope you used a gloss faced pvc as the matt stuff is not very UV stable. And if it is coloured it will start fading sooner rather than later.

🙄 I wish people wouldn’t use foam pvc for exterior signs 🙄
I know it’s cheap but it is not the right material for the job. As John says use Dibond or proper aluminium.

i agree with other comments mate, if you have to use foamex use pamatrim. looks much better finished and will last longer. coloured foamex in warm colours willl fade in under 6 months… worst comes to worst, cover it in vinyl first.

the type of building face you are fitting to is called plasticol cladding.
the best fixing i know of and are the same fisxing that the guys build these building with are called tech bolts. they self tape through the sign, the building and even building frame work. no drilling required. fastest, most secure things ive used. just be careful as there are a few variations on the bolts to suit….

I’ve never had a problem with white “foamex” fading. Perhaps its down to who makes it, there are lots of variations available. Fixing is as rob said, self drill and tap in one go, Depends on how big the sign is to whether it needs space to expand. A 2 x 3 shouldn’t be a problem, if secured firmly with enough fixings around the edge ( one on each corrugation) an 8 x 4 can be done the same but needs to be 10 mm, Screwed to each flat on the corrugation, and it wont deform.

Naa …these signs are 3ft x2ft . I normaly use dibond…..this guys a total skin flint …ill be taking my shirt off my back before this jobs finnished . I aint that keen on foamx as a sustrate i think its run its course 😀

[Robert Lambie]

i feel like i am being realed in here… but…

white doesnt fade mate. only colours will as the suns uv rays sap the hell out of the colour bleaching it milky… we have a 40 grand loss T-Shirt to prove we are right about this, after being stung by VINK Plastics a few years back. shortly after they went bust! funny how they have resurfaced at sign uk this year 😉

quote Robert Lambie:

only colours will

i disagree on the fading of foamex..(only in the circumstances i am going to point out) i have had my main signage on the main busy drag of the a90 now for….phew..many years 😀 but i frog juiced the whole sign with two tins…will post a piccie for you to see sometime tomorrow 😛 the foamex i used was black 😀

Yeah but you never get any sun up there Nik!

I have seen foamex fade badly, especially red and black. More so if south facing. If I have to use it, I cover white in vinyl to get the colour I want.

[Robert Lambie]

but nik…. blacks not a colour 😮 :lol1:

seriously though… if not south facing like G says. it has longer life. sun is the culprit. you used two tins of frog jouce but i am sure that has UV filters in it also.
the worst effected are reds, oranges, yellows…

[Mark Holmes]

hello again !

just to add my two penneth…..foamex face fixed to anything will warp (as i have found over the years and at my expense) – fix it in a panatrim fascia as Rob suggests. If its on to corrugated or onto kingspan cladding, you should be using tech bolts (self drilling screws) or fysher fixings (there a type of spreading anchor bolt) that expand in the holes.

cheers regards brian

Ps are tech bolts the kinda thing id get from B&Q or would i have too go to an ironmongers

Self TappingTech Bolts are the best. If you have a good supplier of fixings in your area they will stock them. Failing that ask any builder they will know the local supplier as they use them all the time. Cheers
