The coating designation G40 represents the type of coating and the weight of the applied coating. The letter "G" indicates that the coating is galvanized, meaning zinc-based. Meanwhile, the number "40" represents the thickness of zinc on the surface of the steel sheet. Galvanized steel sheets are covered with a zinc coating to provide corrosion resistance. The G40 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G40 is the average coat weight and therefore provides moderate protection.

Galvanized sheet is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. Galvanizing is a well-known and effective method to add a protective layer to prevent the exposed steel from being corroded by natural elements. Zinc not only acts as a barrier between the environment and the steel, but it also decomposes first to protect the underlying steel and extend its service life. Zinc is generally represented by Z. Z is the abbreviation of English Zinc. Z120 means that the galvanizing content is 120 grams per square meter. The number after Z indicates the average coating content at three points on both sides of the galvanized steel in grams per square meter.

DX53D galvanized sheet is a kind of galvanized steel sheet. The galvanized layer has good corrosion resistance and can effectively protect the steel sheet from corrosion. Besides, DX53D galvanized sheets have good processing performance and can be used for shearing, bending, welding, drilling and other processing operations. At the same time, the galvanized layer can also increase the hardness and strength of the steel plate, making it more wear-resistant. Its excellent corrosion resistance and processing properties make it widely used in the construction industry. In addition, galvanized steel sheets can also be used to make lightweight steel structures, brackets and other components, effectively improving the stability and service life of buildings.

DX52D galvanized sheet is a galvanized steel sheet material with a thin and uniform zinc layer on its surface. This zinc layer can effectively protect the steel sheet from corrosion and oxidation. In addition, DX52D galvanized sheet also has good processing performance and welding performance, and can meet various building processing and construction needs. DX52D galvanized sheet can be used for various welding operations. Since there is a layer of galvanized layer on its surface, you need to pay attention to the protection of the galvanized layer during welding to avoid welding defects.

DX51D galvanized sheet is divided into cast zinc alloy and deformed zinc alloy. Commonly used cast zinc alloy is zinc aluminum copper magnesium alloy, its casting process performance is good, cooling speed has less effect on mechanical properties, more used in the manufacture of mechanical parts, toys, decorations, household appliances and so on. Commonly used deformation zinc alloys are zinc aluminum alloy and zinc copper alloy. The former contains 4% to 15% aluminum, in order to improve the strength and hardness of the alloy, but also add a small amount of copper, magnesium and other alloying elements. Its high strength can replace some brass or duralumin manufacturing precision forgings. The latter contains 0.7% to 1.5% copper, copper can increase alloy strength and impact toughness, and reduce plasticity.

Galvanized sheet is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.

Hot-dip galvanizing reacts molten metal with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, after pickling, they are cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride. , and then sent into the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.
