    ive been asked to supply some signs for a hospital. they are very particular about what they want.
    the graphics & materials are not a problem but they want the sign fitted on posts use channel & clips. the catch is, they do not want rivetts used for fixing the channel to the sign blank. nor do they want any fixings that can be seen from the front of sign.
    ive heard of an adhesive or tape for this has anyone used it before or know of it?

    are you using ali panels if so youcan use VHB tape by 3M stands for very high bond it aint cheap though we use it a lot its about £60 a roll @ 20mm wide x 25 metres but it is made for exterior use and does stick like the preverbial to a blanket!
    You could try getting the blank panel with the channel rivited grind some of the proud rivit head off and laminate in a 5-7 year vinyl we do this and the rivits are hardly noticable especially after the text is applied sounds like a very pedantic client tell them theres a 2 year waiting list for you to treat their signs!!! regards steve

    hi there!
    we actualy use this stuff on most of our signage, it works very well.
    i like sabaru use the 3M stuff. but we also have another supplier for the same stuff, different make and its less expensive. ill post there details here on monday as i have to get the details from my office.
    in my opinion its way over priced but then again all 3M products are.

    3M? now i think thats the same stuff we use here in the states. theres a few others but not all with as good a rep as 3M.
    i think with products were adhesion is involved its always best using a good brand.
    after all if the sign comes down you have to fix it again. if it hits somone you have a law suite on your hands.

    just off the top o’ me head…

    what about low temp aluminium welding the rails to the back of the plate, I’m not up on aly welding perhaps it woould distort the plate but it’s just a thought…or perhaps an epoxy resin bond instead…

    I too have use VHB tapes for all sorts of things – it’s great stuff – recently we used it on the back of an 8′ x 4′ heavy metal plate sign to fix it to a wooden fascia while we drilled and screwed the plate more permanently…I honestly reckon that plate would not have moved without the screws – it was solid!

    as Rachel said, it depends on the size, weight, position and danger posed by the components.

    more soon

    if we are talking ally plate to ally channel then i would use araldite 2021 structural adhesive,then paint the job,(it will also stand up to powdercoating) if you are using pre painted/powdercoated components then 3M VHB, the one with the red peel off cover will be ok but make sure you use heat and pressure and you will achive a strong permanent joint.
