Why Can Weather Resistant Steel Plate Sculpture Rust But Not Rot?

Nowadays, there are also some plastic arts communities in the garden landscape ecological park often appear a kind of rusty steel raw materials, it shows a kind of industrial production and contemporary art design style, its color and sense of hierarchy is very obvious. The cool surface is combined with the surrounding natural environment, showing a kind of industrial production and contemporary formal beauty. This type of raw material is called weathering steel.

Its uniqueness depends on the thickness of a protective layer that is resistant to corrosion over time when exposed to geographical conditions. Without paint maintenance, the service life of raw materials is about 80 years. The surface looks like the weathering steel of the embroidery is very durable, which is the key reason why the weathering steel raw materials are so hot. So why the weathering steel can ensure the embroidery and not rot?

The basic principle of corrosion resistance of weathering steel plate sculpture depends on, weathering steel raw material is a kind of carbon steel, weathering steel is based on the addition of a small amount of aluminum alloy elements (such as Cu, P, Cr, Ni, Mn, Mo, Al, etc.), so that it has better corrosion resistance than general carbon steel in the air a kind of high alloy steel, its surface in long-term exposure to produce defensive rust layer, Then reasonable conduction block etch material penetration and transport.

Its air corrosion resistance can exceed the general carbon steel 2~8 times, and the longer the application time, the more prominent its weather resistance effect. Weathering steel also has excellent structural mechanics, electric welding and other properties. Because weathering steel can be immediately applied in some natural environments without surface safety protection such as painting, the development and design of weathering steel types and the scientific research on corrosion has been a hot spot in the steel research network.

Relative to carbon steel, the key reason that weathering steel has excellent air corrosion resistance is that after long-term air exposure, the surface surface produces a stable and high-density defensive rust layer, blocking the entry of etch substances, so it has the effect of maintenance.
