Klan is created by matching the colors of the steel with the light (natural) or dark tinted solid beech treads. The wood-effect handrail is in PVC with an aluminum core and is available in light or dark versions, to match the shade of the treads. The railing is made up of steel balusters varnished in black (RAL 9017), white (RAL 9010) or grey (RAL 9006). The finishes are black for the black staircase and grey for the grey and white staircases. KLAN has an adjustable height between 253 and 306 cm. Purchasing one or more supplementary rises, the height of the staircase can reach 377 cm.
