1 thought on “Introduction to galvanized board specifications and classification”

  1. Galvanized plate is a type of steel plate. It can also be said that many of the steel plates are galvanized plates. Galvanized plate is a steel plate with excellent anti -corrosion properties based on the principle of chemistry. This method of preventing steel plate corrosion is very economical and very effective. The use of this process is also very common. They are used to make galvanized plates. The following editors will introduce to you what the technology is galvanized board, what specifications of galvanized plates, and what are the types of galvanized plates.

    What is galvanized board
    Galvanized plates refer to a steel plate with a layer of zinc on the surface. Galvanizing is a frequent economic and effective anti -corrosion method, and about half of the world's zinc production is used for this process.

    The classification of galvanized plates
    The can be divided into the following categories according to production and processing methods:
    ① hot immersion galvanized steel plate. Immersed the thin steel plate into the melted zinc groove to make a thin steel plate with a layer of zinc on the surface. At present, continuous galvanized process is mainly produced, that is, the rolls of steel plates are continuously immersed in a zinc grooved galvanized steel plate with a melting of zinc;
    ② alloy galvanized steel plates. This steel plate is also manufactured by heat immersion, but after the groove is out, it immediately heated it to about 500 ° C to generate a zinc and iron alloy film. This galvanized plate has the closeness and welding of good coatings;
    ③ electro -galvanized steel plate. Making such galvanized steel plates with electroplating has good processingability. However, the plating is thin, and the corrosion resistance is not as good as that of the heat -soaking method;
    ④ single -sided plating and double -sided galvanized steel plate. A single -sided galvanized steel plate, which is only galvanized products. In terms of welding, coating, rust -proof treatment, processing, etc., it has better adaptability than double -sided galvanized plates. In order to overcome the disadvantages of single -sided undetect zinc, there is another kind of galvanized plate with thin layer of zinc, that is, double -sided galvanized plates;
    ⑤ alloy and composite galvanized steel plate. It is a steel plate made of zinc and other metals such as aluminum, lead, zinc, etc. This steel plate has excellent rust resistance and good coating performance;
    In addition to the above five types, there are also color -galvanized steel plates, print -coated galvanized steel plates, polyvinyl chloride stacked layer galvanized galvanized layer galvanized Steel plates, etc. But the most commonly used is still hot -dip galvanized plate.
    Min -main production plant and import production countries:
    ① major domestic production plants: martial arts, Angang, Baosteel Huangshi, Zhongye Hengtong, Shougang, Pan Gang, Handang, Malaysia, Fujian Kaijing, etc.;
    ② foreign countries mainly produce state -owned Japan, Germany, Russia, France, South Korea, etc.

    The output of galvanized plates every year, because the construction industry and various industries are constantly developing. Board, so the market prospects of galvanized boards are very good.
