    Hey all, Hope all are well….

    I’m after some info, we used to manufacture our fret cut tray’s with a joining strip like the attached, our supplier and others have stopped stocking / manufacturing the Z section in these measurements…

    How do you guy’s do this? The added weight of the acrylic using the composite joiners can dip in the joined areas as not strong enough….

    Hope this makes sense??

    Interlocking sign Channel, as shown. Works great, vertically and horizontally.
    Comes in different sizes and lengths, so watch you are buying based on like for like, if shopping around.

    You can buy it from Righton: https://www.rightonblackburns.co.uk

      This is also designed specifically for the back of aluminium and ACM trays for ease of fitting to panels and with a leading edge for easy alignment on site when fitting…

          Hi Gary,

          the extrusions are made of aluminium for rigidity. This also means if you are putting them on aluminium trays you can fix them (using high temperature double sided tape or glue) before painting. This gets the tongue part painted the same colour so if you panel joint is not 100% perfect on site at least the tongue is the same colour. The tongue has a line on both sides so whether you apply from the face or back you can ensure that you finish it in line with the end of the panel (although tolerance for mis placement is built in anyway). The groove is fixed so that the start of the leading angle finishes in line with the end of the panel too.

          The extrusions are supplied in 2000mm lengths for you to cut down to the size you require. If you need a joint over 2000mm you can stagger the joints from one panel to the next (would also suggest another piece of tongue spanning either side of the joint on the inside to stiffen this).

          The extrusions are sold in packs of 10. The tongue (our stock code XT) is £7.30 per 2m length and the groove (XG) is £8.10 per 2m length (plus VAT and carriage (currently £37.50 to cover the weight of them and packing (or you may collect if you are near to us?)). No tape/adhesive is supplied as obviously varies depending on the substrate you are using.

          This is our own extrusion that we designed initially for our own use in aluminium and ACM panels before offering out to the trade. Some companies buy 10 at a time and we have others that buy 50 or 100 off of each if they have rollouts, just depends on your needs. Works equally well for panels in frames too. If you would like a small sample please let me know and can pop in the post for you to see.

          Hope this helps.

    i have never saw either of these joining strips but they look like they would work great!
    the tongue and groove one looks more like what we currently do but using double sided foam tape and cuttings of composite or ally.

      Hi Mark, yes we used to make them out of offcuts too! Will work exactly the same but with the advantages of the stiffness of the aluminium extrusion and of course the angled leading edge when you come to slide the panels together.
