How long does Corten steel last outside?

    Corten   steel is an important weatherproof material. Generally, it is used in construction and design, and its application is relatively wide. The use of weathering steel is more concerned about its service life, how is the service life?

   Artificial aging test of weathering steel 12000 hours, matching the use of natural environment for more than 38 years, because the adoption of HTRE composite technology makes the product of high and mild nano-glass fiber composite layer can display strong anti-impact function, 4 kg of steel ball at the height of 3 meters free fall on the tile surface without cracks, its antiimpact function is more than 3 times that of synthetic resin tile with the same thickness. It is difficult for hail with moderate intensity below to damage the product. The product has passed the low-temperature drop hammer test and has passed 10 freezing-thawing cycles without any phenomenon such as empty drum, bubbling, peeling or cracking. Weathering steel, another name for atmospheric corrosion resistant steel, is a low alloy steel series between ordinary steel and stainless steel. Weathering steel is made of general carbon steel with a small amount of copper, nickel and other corrosion resistant elements. It has the characteristics of high quality steel, such as strength, plastic extension, forming, welding and cutting, abrasion, high temperature, fatigue resistance and so on. The weatherability is 2~8 times of common carbon steel, coating property is 1.5~10 times of common carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance and life extension, thinning and consumption reduction, labor saving and energy saving.
