The more beautiful the landscape design

In the landscape design, we can often see a kind of material, the surface is a layer of red material, the touch is very rough, the texture is very special. It does not look abrupt, and even perfectly combined with plants, in the contrast of rough and delicate, cold and warm, soft and hard, condensed into a rich design context, its name is weathering steel!

Weathering steel, also known as corrosion resistant steel, originated from North America. It is a series of low alloy steel between ordinary steel and stainless steel. The weathering steel is made by adding a small amount of copper, nickel and other corrosion resistant elements to plain carbon steel. It has the characteristics of toughness, plastic extension, forming, welding and cutting, corrosion, high temperature and fatigue resistance of high quality steel.

As early as the beginning of the 20th century, some avant-garde foreign artists used steel in sculpture creation, because steel corrosion is a natural state of the material itself, which is very consistent with the authenticity principle of artistic expression. Steel has become one of the materials of modern landscape plastic art design. After ordinary steel rusts, it will gradually corrode and age until it is damaged. The emergence of weathering steel makes designers have the opportunity to make full use of the corrosion form of steel to express in plastic art creation.

Principle of weathering:

Rust in the natural climate results in the formation of a dense oxide layer between the iron and steel layer and the matrix. Due to the existence of this dense oxide film, oxygen and water in the atmosphere are prevented from infiltrating into the steel matrix, thus improving the atmospheric corrosion resistance.

Characteristics of weathering steel:

1. Corrosion resistance, corrosion resistance, atmospheric corrosion resistance is 4-8 times higher than that of ordinary steel.

2. Steel parts can resist corrosion and prolong life, reduce thinning and consumption, save labor and energy (the weather resistance is 2-8 times that of plain carbon steel).

3. Green environmental protection does not need initial painting (in areas with serious air pollution or non-particularly humid); it can reduce the use of fireproof coatings and fireproof coating, so as to reduce pollution, shorten construction period, reduce cost and reduce maintenance. it is a kind of economic steel with "green environmental protection" and sustainable development.

4. The material can be recycled and is very low-carbon and environmentally friendly.

Design of weathering steel in landscape:

1. Outstanding visual expression. Corroded steel plates will change over time. Its color brightness and saturation are higher than ordinary structural materials, so it is easy to stand out under the background of garden and green plants. In addition, the rough surface caused by steel plate corrosion makes the structure richer in volume and quality.

2. Distinct ability to define space. Because of the high strength and toughness of steel plate, it is not as limited as the thickness of masonry material caused by structure. Therefore, very thin steel plates can be used to separate the space very clearly and accurately, making the site concise and lively, and full of power.

3. Strong ability to shape the body. Like other metal materials, corroded steel plates are easier to shape into rich and varied shapes and maintain excellent integrity, which is difficult for wood, stone and concrete to achieve.

4. The changing language of time. The corroded steel plate will change with time, and its color will change greatly under the influence of environment and climate. After being placed for a long time, it is easy to change from bright reddish brown to dark blue-gray. With the aging of time, the unique color and texture of the weather-resistant steel full of beauty can reflect the unique artistic charm. Can trace the sense of history of the site, record the instantaneous sense of time, extend the vitality of the site, so that the limited materials can "symbiosis" with each other, reflecting the concept of sustainable design.

In addition to being used in building structures and facades, weathering steel can be seen in landscape architecture, retaining walls, landscape bridges, steps, sculptures, guide signs, planting ponds and other landscape sketches.
