PRODUCT DETAILS

Galvanized strip steel is a kind of raw material called (zinc), which is used to coat the long and narrow strip steel which is cold-rolled or hot-rolled to varying degrees. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the hot-dip galvanized steel pipe substrate and the molten plating solution, forming a corrosion resistant zinc iron alloy layer with compact structure. The alloy layer is integrated with the pure zinc layer and the strip steel matrix. Therefore, it has strong corrosion resistance.

DX51D galvanized sheet material is a non-ferrous alloy mainly composed of zinc as the matrix and other elements. The main alloy elements are aluminum, copper, magnesium, etc. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and is resistant to atmospheric corrosion. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy. The commonly used cast zinc alloy is zinc aluminum copper magnesium alloy. Its casting process performance is good, and the cooling rate has little impact on the mechanical properties. It is mainly used to manufacture mechanical parts, toys, decorations, household appliances, etc.

Use of galvanized strip steel: strip steel is widely used in the production of welded steel pipes, as the blank of cold bending section steel, and in the manufacture of bicycle frames, rims, clamps, washers, spring blades, saw blades, hardware products and blades. The use of high hot dip galvanized strip steel is naturally associated with the application of galvanized strip steel in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce and other industries.

Production process:
The first stage: pickling and decontamination of the whole roll of strip steel to make the surface bright and clean.
The second stage: after pickling, it is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank for galvanizing.
The third stage: after the strip steel is galvanized, it is rolled up and put into storage. The galvanized layer can generally not be less than 500g/m2 according to the customer's needs, and any sample shall not be less than 480g/m2.
Post treatment of galvanized strip steel includes passivation, pre phosphating and oiling. First of all, passivation treatment should be carried out on the galvanized strip steel, which can improve the surface structure and luster of the zinc coating, improve the corrosion resistance and service life of the zinc coating, and improve the adhesion between the coating and the base metal. The chromate passivation treatment is mainly used. Some activators, such as fluoride, phosphoric acid or sulfuric acid, are added to the passivation solution to obtain a thicker chromate film after passivation. When there is fluoride in the passivation solution, the surface tension of the steel strip can be reduced, the film forming reaction can be accelerated, and the chemical polishing effect can be increased to make the passivation film fine and bright.
