1m - cross-section can be + - 2mm. Aluminum profiles for LED strips: Profiles represent the simplest design solution for the implementation of linear working, decorative, and orientation lighting systems. The aluminum profile itself is designed for direct wall mounting (screwing, nailing, gluing) and includes grooves for sliding in LED lighting elements (LED strips or LED strips) and a groove for sliding in the cover plexiglass. Holes for power conductors, bushings, mounting and drainage holes, etc. can be drilled into the profile at any point. The aluminum profile is not only a decorative element, but it is also an important cooling element for heat dissipation and thus prolongs the life of LED lighting systems.
