With their automatic Radial sliding door systems BLASI offers a comprehensive programme featuring bi-parting curved sliding doors, bi-parting drum sliding doors with small or large passage widths as well as oval sliding doors. BLASI radial door systems have been perfected technically and from a quality point of view and can accommodate diameters of up to 10 metres. They are equipped with barely audible drive mechanisms, which can be integrated in the ceiling or concealed under the finished floor. Concealed underfloor drive units in conjunction with all-glass Radial door systems offer a particularly light and transparent visual effect and are the preferred choice as far as glass facades are concerned. Radial door systems afford complete freedom of choice: be it brass, chrome, stainless steel, any RAL colour or bespoke radius, the creative options are unlimited. Radius, diameter and overall height are variable. The minimum installation depth requirement for a concealed underfloor drive unit is 220 mm.
