A material used in some landscapes weathering steel, from a distance the surface looks like rust, texture is very special, weathering steel, also known as corrosion-resistant steel, first originated in North America Corten steel, is a low alloy steel series between ordinary steel and stainless steel, weathering steel from ordinary carbon steel add a small amount of copper, nickel and other corrosion-resistant elements and become.
General steel, long-term in the open air, rain and sun, weathering corrosion inevitably rust, and weathering steel why will long maintain the nature, weathering steel is rusted in the natural climate, so that the steel material in the rust layer and the substrate between the formation of a dense oxide layer. Due to the existence of this dense oxide film, it prevents the infiltration of oxygen and water into the steel substrate in the atmosphere, thus improving the resistance to atmospheric corrosion.
Corten steel is used in landscape materials not only from its appearance, but also the integrity and structure of the landscape. There are also many highlights, first of all it has a very prominent visual expression, the rough surface produced by the rusting of the steel plate makes its structure more textured.
At the same time it has a strong shaping ability, which is difficult to achieve wood, stone and concrete, the distinctive space definition is a lot of people love, the picture below like a screen light baffle, not only can bear the natural ravages not to damage, but also gradually change over time, from bright red-brown into a dull dark blue-gray, so that it reflects a different artistic charm.
