Many people do not know that when weathering steel leaves the factory, there is no rust layer on its surface, which is no different from ordinary steel. The effect of rust can make it rust naturally outdoors, or it can rust manually with liquid medicine. Choose the right method according to their needs. Some customers need to see the beautiful rust red immediately, so they need liquid medicine to rust manually. How should they rust? First of all, it is recommended to try to avoid handling in sunny days or outdoors. In rainy days, handling at night can be avoided as much as possible. Secondly, the liquid medicine can not react with the atomic ash. The water sprayed on the day must be thoroughly drenched with clean water, not the next day. We need to pay attention that the liquid medicine can be used directly without adding water. Wear protective equipment when using it. Secondly, if the material is cut, bent and other processes at an early stage, please check whether there is oil stain on the surface. If there is a need to clean, rust treatment can be done after the water is dry.
We can allow the moisture of weathering steel to evaporate naturally. After the surface is completely dry, it will show rust color, rust red oxide film with strong stability, uniform color thickness, and is not easy to be wiped off. In an outdoor environment where the temperature is 20 degrees, rust treatment can be completed in two or three days to quickly produce a sense of surface roughness, improve vision and feeling, and improve the design effect. Generally, it takes a year or two for weathering steel to rust naturally, This treatment will not be affected by the geographical environment, weather and location, and will not corrode and affect the subsequent rust layer. This kind of steel plate is very economical and cost-effective, and its quality is very good. It is very popular when used. Its corrosion layer will not be easily damaged, which can reduce construction costs. It can be divided into base course and transition during welding. It is different from other types of steel during operation. Corresponding electrodes shall be prepared during welding to ensure better results.
When we choose weather resistant steel, we can't just pursue low price, but choose a good effect and quality. We need to consider many factors to achieve the ideal effect!
