Weather Resistant Steel Plates are used in applications that last longer and are exposed to the atmosphere for long term. Applications that have to have plates in the open often use these Corrosion Resistant Steel Plates in combination with pipes, fittings and flanges. The material can vary in composition but all the weathering steels types have low carbon, less than 0.3% by weight. This low carbon allows for the ductility and toughness of the Weather Resistant Steels Sheet. The name comes from the ability of the material to withstand weathering or atmospheric conditions over time. The specialty of the Corten Weather Resistant Steels is that it forms an oxide layer on the surface. This oxide layer cannot oxidize any further, so it acts as a barrier between the steels inside the layer and the oxidizing agents to the outside of the plates.
The Weather-resistant Galvanized Steels is protected further by having the galvanized layer in the first place. To damage the plates, the galvanized layer will have to be corroded first. The Corrosion Resistant Metal Plate has this complex oxide layer that forms over time and mostly slowly. So this type of metal plates are an effective investment for long time. This oxide layer is called the patina. It is a complex chemical composition. The Atmospheric Corrosion Resistant Steels Plates can get damaged. In case where the damage takes place, the oxidation starts again and the patina forms again. There are other techniques to improve the resistance such as the Corrosion Resistance Zinc Plated Steels where zinc acts as a protective layer. There are many other elements that could be used as coatings such as in the case of Cadmium Plated Corrosion Resistant Steels. Please contact us for any of the weathering steels plates requirements.
