They consist of the front made from aluminum sheet 2 mm thick, sides from aluminum tape 1.0-1.5 mm.
The letters are mounted on distance blocks and then to the wall, or directly.
Available width of the tape ranges from 55 to 160 mm, which is adjusted to the size of the letter. We give 5 years of warranty on those letters.
There is a possibility of making the letters from styrodur, lacquered with latex paint RAL and improved with plexi or Dibond board. They can also be made from PCV and lacquered as well. However, styrodur and PCV are not too durable and hence are suitable mostly for the interior.
