The surface of steel usually has a galvanized layer, which can to some extent prevent rusting of the steel. The galvanized layer of steel is generally constructed through hot-dip galvanizing or electrogalvanizing. So, what are the differences between hot-dip galvanizing and Ningbo electrogalvanizing?

1. What are the differences between hot-dip galvanizing and Ningbo electroplating

The principles of the two are different. Electrogalvanizing is the process of attaching a galvanized layer to the surface of steel through electrochemical methods, while hot-dip galvanizing is the process of soaking the steel in zinc solution to attach a galvanized layer to the surface of the steel.

There is a difference in appearance between the two, and if the steel is electroplated, its surface is relatively smooth. If the steel is hot-dip galvanized, its surface will be rough. The coating of electroplated zinc is mostly between 5 and 30 μ m. The coating of hot-dip galvanizing is mostly between 30 and 60 μ M.

The application scope is different. Hot dip galvanizing is mostly used in outdoor steel such as highway fences, while electrogalvanizing is mostly used in indoor steel such as panels.

2、 How to prevent rust on steel

1. In addition to rust prevention treatment of steel through electroplating and hot plating, people also achieve good rust prevention effects by coating rust prevention oil on the surface of steel. Before applying anti rust oil, it is necessary to clean the rust on the surface of the steel, and then evenly spray the anti rust oil on the surface of the steel. After applying anti rust oil, it is best to wrap the steel with anti rust paper or plastic film.

2. To avoid rusting of steel, we also need to pay attention to the storage location of steel. For example, do not store steel in damp and dark spaces for a long time, and do not directly place steel on the ground to prevent moisture from entering the steel. Do not store acidic substances, chemical gases, etc. in the space where steel is stored, otherwise it is also prone to product corrosion.
