This copper revolving door is a dynamic sculpture of space aesthetics, which perfectly integrates the spirit of craftsmanship with fluid mechanics. Inspired by the Tang Dynasty rolling grass pattern, the hand-forged brass blades show a gradual luster from champagne gold to twilight ash after 72 oxidation processes, and each copper plate has a precision bite error of less than 0.2 mm, which is like rolling a gilded folding fan. Built-in silent magnetic bearing system, energy consumption is 40% lower than the traditional revolving door, the copper surface automatically generates a nano hydrophobic film in heavy rain, water droplets slide along the preset artistic track into the door curtain show.

Cultural totems can be customized - the Palace Museum window mulleons, Dunhuang flying ribbon or modern abstract lines etched on the leaves, intelligent system automatically adjusts the speed according to the flow of people, the art gallery in peak hours, and the silent copper carving device in low peak hours. The copper surface is equipped with a tactile temperature control layer, which maintains a skin-friendly touch of 20 ° C in winter, and the oxide layer precipitates with a unique coating over seven years. The blockchain chip built into the door shaft records the mechanical data of each rotation, providing a structural health file for the century-old building. When the morning sun penetrates the 0.3mm transparent copper carved filter screen and projects the flowing silhouette of "A Thousand Li of Rivers and Mountains" on the ground, this door becomes the time axis connecting commercial space and art field.
