As early as the beginning of the 20th century, some foreign avant-garde artists used steel for sculpture creation. Because steel corrosion is a natural state of material itself, it is in line with the principle of authenticity of artistic expression. The steel that has been used for a long time has become one of the materials of modern landscape art design. . Ordinary steel will gradually corrode and aging until it breaks, and the appearance of weathering steel gives designers the opportunity to fully utilize the rust pattern of steel in the creation of plastic arts. It has a strong physical shaping ability. Like other metal materials, corroded steel sheets are easier to shape into a variety of shapes and maintain excellent integrity, which is difficult to achieve with wood, stone and concrete.
