The sides and the back of the “Profile 5” letter are made of aluminium, stainless steel (Inox sheet metal) or galvanized sheet metal, which is then coated in the selected colour shade according to the RAL colour scale. The 3D letter’s head is made of coloured or white Plexiglas that lets light through. Directly illuminated “Profile 5” is built like Profile 4. The difference is that the Plexiglas forehead is not attached to a letter with an aluminium bracket, but is surrounded by an F ribbon in the colour of the side or the forehead. For 3D illumination of the inscription, we use energy-saving and high quality LED Samsung modules.
