Pay attention to anticorrosion of galvanized sheet incision

Pay attention to anticorrosion of galvanized sheet incision


If the galvanized plate is secondary cutting processing, in fact, the section is not galvanized, if not treated in time, it may also lead to the internal steel plate rust. Therefore, the daily secondary processing of steel plate, basic rust prevention work and detection is also very important. And rust prevention oil should also be selected properly, so as to effectively extend the service life of the steel plate.


Because there is a galvanized layer on the surface of the galvanized sheet, its corrosion resistance is relatively strong. The galvanized layer is mainly to avoid the corrosion of the steel plate, so as to prolong its service life. And high-quality steel plate surface galvanized layer thickness is uniform, there is no leakage of plating, also can ensure good corrosion resistance, the service life is generally more than a few decades.


Because the steel plate can form the shape we need to process after punching, but the cutting part of the section is not galvanized layer, so over time there will be incision rust. And we should pay special attention to the specific environment in addition to rust prevention, such as sea export, then we must choose some anti-rust oil resistant to humidity and heat, so that long-term transportation will not appear rust problems. If necessary, salt spray testing should be done in advance.


In fact, most businesses pay great attention to the rust prevention of the incision position, but pay special attention to the use of water-based rust prevention agent, so it can only be short-term rust prevention. If it is to long-term rust prevention, the use of this kind of rust prevention agent can not achieve good results. As far as possible, we should choose special anti-rust oil, so that the anti-rust effect is good, and the service life is long, but also to avoid the appearance of rust in the galvanized sheet incision position.
