Natural stone marble, granite, wood, decorative board, stainless steel, titanium plate, aluminum alloy and aluminum-plastic plate, azurite, etc. They are all available decorative materials, and their shapes can be square columns or cylinders. The specific materials and shapes are determined according to the overall style of the living environment. If the space atmosphere is a soft and depressing theme, the shape of the column should be decorated with simple and bright circular columns. The facing material of the column decoration is best to be the same as the main material of the wall, which echoes each other and has a good overall feeling. In some public places,' stainless steel and mirror materials are often used to wrap columns', but at home, this rigid and lifeless material is not suitable. If the space is large and the column is separated from the body, the decoration of the column will be more serious because the position of the column is prominent. If the decoration and modeling are handled properly, it will become the indoor visual center, enrich the spatial level, activate the spatial atmosphere, and make people feel novel and unique. If you use marble, granite or wood as decoration, you should pay attention to the treatment of mosaic and the modeling of stigma and column base, so as to be concise and meaningful. If there are multiple pillars in the same space, the decoration should be coordinated.
