Generally speaking, the occurrence of white rust on galvanized steel sheets is caused by transportation or storage.

According to the GNEE STEEL galvanized sheet manufacturer, if the galvanized sheet is stored in a humid environment for a long time, a layer of white rust will easily form on its surface.

Surface production and processing types of stainless steel cold-rolled strips

Products above ST13 are used in industries that require low-alloy plates, such as the automotive industry, fuel tanks for diesel engines, etc. The actual type to be used depends on the drawing requirements.

How to choose galvanized sheet cleaner

The difference between galvanized sheets and aluminum-zinc alloy coated sheets lies in the coating. A layer of zinc material is evenly distributed on the surface of the galvanized sheet, which plays an anode protection role for the base metal.

Hot-dip galvanizing strip steel is a commonly used anti-corrosion treatment process.

Hot-dip galvanized strip steel is a steel material in which a steel strip is immersed in a hot-dip galvanizing solution to form a layer of zinc covering the surface of the steel.

I believe many people have seen square pipes. During the anti-corrosion construction process of oil (gas) pipelines, the surface treatment of square pipes is one of the key factors that determine the length of the anti-corrosion service life of the pipeline.
