The advantages of weathering steel are very many, good color, thinning, consumption reduction, labor and energy saving is a kind of green environmental protection, sustainable development of economic steel.
However, there are also shortcomings. At the early stage of the formation of the rust layer, the weathering steel will form traces of rust water on the surface and even pollute the ground due to the instability of the rust layer. After the rust layer becomes a uniform dark brown, it will be stable. But we can use chemical treatment, can quickly form a uniform layer of rust to increase its protection, improve corrosion resistance.
