An aluminium composite sheet provides us with a base to mount our lit acrylic letters on. But in many use cases, customers ask us to do away with this base ACP frame entirely. We are requested to mount the letters directly on the wall or an existing metal frame.
Stand Alone Acrylic Letters With Lights. Why Are They Needed?
Assume for a moment that the customer has a well-finished wall of granite. It makes no sense for us to cover his premium looking granite tiles with yet another layer of aluminium composite panel.
Alternatively, the client may have an existing metal frame or steel girders in place at the installation site. Our job is to then reduce his cost by installing the 3D letters directly onto this frame. Doing away with the base frame does help in saving money.
In many malls, you’ll see glowing letters hanging from the ceilings without any visible back support. Standalone letters shining in front of the glass facade of premium retail stores add to the aesthetic value of the same.
Two Prerequisites for Stand Alone Acrylic Glow Sign Board.
Stand-alone letters jobs come with a couple of conditions. Fulfilling them. Will result in a beautifully finished job. The two things we pay particular attention to are…
- We need to connect an electrical wire to each individual letter or logo of the sign. Remember, these letters have LEDs encased inside. Power needs to be supplied to these LED modules. In the case of an ACP base frame, the wires are easily concealed behind the metal panel.
But exposed wires do look ugly if there is no place to hide them. To work around this issue, we back drill on the wall where the letters have to be installed. This means we make a small hole behind each letter and loop the wires from behind the walls.
In case the letters are installed on a frame, we hide the wires in the structure’s hollow metal pipes.
- Since there is no proper base or support for our letters, we prefer to use thicker and more robust materials to fabricate the signage. The letters are still made of laser cut acrylic, but we may choose to opt for a 5 mm thick sheet in place of the more standard 3 mm.
But while the front and sides of the letters are made of acrylic, to allow light to pass through, the back surface/base of regular letters is generally cut out of a 5 mm thick sunboard. For stand-alone letters, we recommend the use of a metal / ACP sheet for the back surface.
These best practices ensure significantly enhanced strength for our 3D letters. Crosswinds on high rise buildings pose a very real danger that needs to be considered by sign makers.
I have personally witnessed gale force winds tear apart a huge, 40-feet board, from the seventh floor of a high rise.
While thankfully no was injured in that incident, it highlights the fact that fabrication and installation of shop signs should be commissioned from agencies with some level of experience rather than blindly contracting out the job to the lowest bidder.
