There are two methods. One is a relatively stable sculpture, which is light and heavy and has a large landing area. It can be done by iron expansion screws at the bottom and welding to the sculpture steel keel by electric welding. The large center of gravity is not very stable. The steel plate on the ground must be welded to the internal keel firmly. The ground must have embedded iron. Layer steel plates are welded firmly, and the stone structure or flowers are buried outside the foundation to expose the steel structure outside the sculpture.
