Weather-proof/Corrosion Resistance Steel Normal specification: 2-16*1500*6000/c.
Commodity description: It’s kind of low alloy steel which between normal steel and stainless steel. It’s
manufactured with the corrosion resistance element like copper, nickel based on the nomal carbon steel. It has
the character of tough, extensibility, moulding, welding and cutting, ablation, high temperature, antifatigue and so on. Its weather-proof capacity is 2-8times and coating is 1.5-10times compare to normal carbon steel. It also characters with antirust, lifetime extension, low consumption, labour saving and energy conservation. It was mainly used in the industry of railway, vehicle, bridge, tower which are exposed in the air in long time. It can be also used to manufacture container, railway vechical, oil derrick, seaport building, oil production platform which contains the corrosive medium called sulfuretted hydrogen
