Weather Resistant steel
Weathering Steel plate can be exposed to the atmosphere without painting. It begins to rust in the same way as ordinary steel.
But soon the alloying elements in it cause a protective surface layer of fine-textured rust to form, thereby suppressing corrosion rate.The alloy composition and weight percentage of weathering steel are: C: ≤0.12, Si: 0.25~0.75, Mn: 0.2~0.5, S ≤0.02,P:0.06~0.12, Cu: 0.25~0.5, Cr: 0.3~1.25, Ni: 0.12~0.65, the rest are Fe and trace elements.

Surface Treatment At the early stage of research and development, weathering steel was used as an industrial material in the fields of
construction, ships, and railways. Widely used in the production of train cars, containers and bridges. As a new generation of advanced steel materials, weathering steel has outstanding visual expression and the longer it is used, the more prominent the corrosion resistance is. The rough surface produced by the corrosion of the steel plate makes the structure more volume and quality. What makes it special is that when exposed to the natural environment over time, the surface forms a protective layer against corrosion. No paint protection is required, and the material life is more than 80 years. Schematic diagram of the color change of the weathering steel surface▽
