The use of natural stone honeycomb panels as a building interior and exterior decoration has a long history. It is a beautiful, strong and durable decorative material. However, the shortcomings of natural stone are also obvious. It has large weight, strong water absorption, and is easily crushed by external force. Some stone has invisible cracks. After the installation of the outer wall of the high-rise building, the cracks gradually increase due to the long-term influence of positive and negative wind pressure, so there is a great safety hazard.
The author recently witnessed a magical stone decorative board at a seminar organized by the China National Association of Aluminum Products Committee in Shanghai. A 4 cm thick stone decorative panel was suspended, and four strong men stood on the same side. The suspended part in the middle of the stone decorative panel was pressed into an arc due to the force, but it was neither broken nor damaged. When the four men walked down, the stone trim panels returned to a flat state. It’s just a god! This is a stone decorative board, it’s like a spring pad!
