SPAZIO wall panel is fixed by keel, which can be directly buckled on the cement wall. The keel can be used to adjust the top, bottom, left and right, and front and back of the wall panel to ensure that it is in a horizontal state. The gap inside the wall panel can be reserved for potential, which is very convenient for maintenance. . In terms of materials, various materials such as back-painted glass, leather, slate, and plate can be used; the shape can also be divided and designed at will.
