One ERCO product pervades throughout all four usable levels with their combined floor area of 11,000m2: the Hi-trac track and light structures. The aluminium profile has a rectangular cross section of 36mm x 72mm and can therefore span large distances with just a few suspension points. The underside is finished as standard as a 3-circuit track, the topside as an empty profile or as a luminaire for T-16 fluorescent lamps for indirect lighting - making Hi-trac an extremely flexible tool.
