On the staircase side of an old restored house, we installed a balustrade perfectly sawn on it. From the survey stage to the installation of the balustrade, several steps have taken place. In fact, the installation was not an easy pie to make. The renovated ancient structure presented all the structural features of an old staircase. The Lamberti’s team patiently worked with wooden shapes, preassembling them and purposely using stainless steel knobs to fix the metal panels to the staircase side. It has been possible to successfully install a completely customized balustrade with CNC cuts. The carbon steel sheets have been cut with our waterjet machines and then acid-etched to obtain a dark brown finish.
