Does anyone know of any problems fixing vinyl to steel?

[Peter Normington]

Neither the vynyl, nor the galvanised sheet will be around then,
Long life use powder coated ali, and 10yr cast.

for really long life forget vinyl or paint, engraving or casting is the solution.
in stone or bronze?

galvanized as you will know is two ton mate… unless guillotined forget jigsawing or ripping it, without the use of a x-wing fighters blast shield and bullet proof vest. :lol1: :lol1: then file the nice edges smooth 😀

seriously though… if its coming in fresh off the metal suppliers truck you will have to degrease it big time. from memory it seems to have an oily film on it. meths or similar should do the trick, but wipe with fresh rag several times. “the vinyl hates the film” and it will curl back off it at the edges in a few days.
if workshops freezing remember and heat it once applied.

651 will be fine for a flat sign like this, but when you say its a traffic sign. make sure the background colour, or all colours for that matter, shouldn’t be reflective?
just clear that with whoever is ordering it. maybe get them to sign something too…

Thanks Peter,

I was just being a little flippant, I really just need to know if the vinyl will last a good few years fixed to the plate, It’s a stop sign which is attached to a chain to stop people parking when the place is shut.

thanks

Thanks Mr Lambie,

The galv would be a plasma cut 600mm diameter (with a small hole both sides for the chain) , they said they don’t want it to be reflective just red/black & white.

I don’t have the facility to lamianate yet so is there another way to protect it, if it needs it at all, my supplier has informed me that oracal 651 has been upgraded to a 5-7yr product.

cheers

no need to laminate mate, just make sure its degreased properly, apply with colours needed. then heat in well… or just lean it againts an hot radiater for 20 minutes you will get a nice bond 😉

[Peter Normington]

If you are having the blank galvanised after its cut no problem, however if its cut after being galvanized, you will need to seal the edge in some way, or it will rust.. Enamel or auto paint with a good primer?
Or for a nice finishing touch, slit some coloured tube on on side fill with silicon and wrap round the end. You can get purpose made edging, like used to be used on older type car doors etc. Dont have a source though.

peter, i hardly ever have to use galavanised sheets. infact havent in years, back then it was once in a blue moon, but… i guilotined anything i had to cut and never sealed it ever, but never had any probs? 😕

[Nicola McIntosh]

thats what i thought…galvanised steel never rusts as i buy a lot of galvanised wire….costs a bomb but it never rusts at all 😀

To be totally honest, I’d be using a cast for this job anyway.

such a mall job, the extra cost for the material will be minor.

Cast is going to give you the maximum life, and it is a premium product that will withstand the bigest temperature changes.

Applying to gal material, remember ‘cleanliness is the most important step’. As Rob says, it will have an oily film and IPA or method a few times before applying.

As a laminate, just flood coat with a clear cast to finish.

It will last forever.

Just my 2c

Rob Galvinized steel will rust when you cut it , on the exposed edge.
Galvnising is steel coated with zinc by electrolosys to prevent it rusting,

The thicker the gauge, the quicker the edge will rust.

Personally I would use powder coated aluminium, or fibreglass. both can be bought off the shelf for this type of job.

I suspect Biggles knows what hes talking about… his plane has plenty of sections :plane:

peter the galvanised stuff i buy in i cut the ends off bare to send out to customers…..it still does not rust, and i have been using this wire since 1988….im just intrigued as the stuff i use is for the yaughty folk, never had a problem yet 😀 sorry peter but you know me….like to find out everything 😉

[Peter Normington]

Nik. galvised wire will rust but right on the itsy bitsy end you have cut, so it won’t be a problem. along a long cut edge it will show after a while.

I thought the yachty peeps used stainless anyway?

not the tight ones peter….. 😉

haven’t had them visit yet… 😉

[Robert Lambie]

peter the stuff i have used is 1-1.5mm at most. still never noticed any rust mate.
i would use signicolour from amari plastics. its a 2mm auto paint coated aluminium and comes in various colours, supplied by alcan. great stuff for things like flat metal cut letters etc

[Peter Normington]

Rob you may not have noticed but it does happen

Just been outside to check

Peter

[David Rowland]

is that the bottom of the outside loo? I can imagine that rusting 😮

[Lynn Normington]

don’t be silly Dave we don’t have the luxury of an outside loo we have to make do with one in doors :lol1:
when we are sunning ourselves at the bottom of the garden it really would be handy to have an outside one cause I can run all that quick now 😎
