The prefabricated indoor staircase combines the beauty of solid wood with steel. The fixings are in chrome-plated aluminium and the handrail is in wood-effect PVC with aluminium core and available in a shade to match that of the tread. The railing is composed of painted steel balusters and crossable stainless steel cables in five different configurations. The staircase is characterised by a landing which can be adapted during installation and can have three different configurations (trapezoidal, triangular or circular) so that the staircase can be installed in openings of various shapes. The direction of rotation, clockwise or anticlockwise, is decided at the time of installation. The diameters are 118, 128, 138, 148 and 158 cm.
