PPGI is the abbreviation of Pre-Painted Galvanized, that is, pre-painted galvanized.

Usually refers to PPGI Coil (color-coated galvanized coil), PPGI Sheet (color-coated galvanized sheet) and other steel products.

It is based on the galvanized coil and then covered with a certain technology and then covered with colored paint to give the product more colors, and this colorful and beautiful surface makes it more widely used.

Galvanized coil is a thin steel sheet that is dipped in a molten zinc bath to make a layer of zinc adhere to its surface. It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously dipped in the galvanizing tank with molten zinc to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel panel is also made by hot dip method, but it is heated to about 500℃ immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized coil has good paint adhesion and weldability.

Galvanized Plate Chemical Composition:

Application:

PPGI plate products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grids, etc.; the light industry industry uses it to manufacture home appliance shells, civil chimneys, kitchen utensils, etc., and the automobile industry is mainly used to manufacture corrosion-resistant parts of cars, etc. ; Agriculture, animal husbandry and fishery are mainly used for grain storage and transportation, frozen meat and aquatic products, etc.; commercial is mainly used for storage and transportation of materials, packaging equipment, etc.

• It has high strength and strong deformation ability, and has good adhesion and welding performance.
• It has the characteristics of good overall rigidity, good seismic performance, good thermal insulation performance, long service life, large space, short construction period, and low investment. This series of steel has high strength and is generally used in house construction.
• It has strong corrosion resistance, has strong corrosion resistance, and has a smooth surface and exquisite appearance. It can generally be used for surface building materials or structural parts, and can be used for roofs, walls, waterproof boards, trenches, underground Pipes, snorkels, upholstery, fencing, steel frames, etc.

Classification by production and processing methods

• Hot-dip galvanized steel sheet. Dip the thin steel plate into the molten zinc tank to make the thin steel plate with a layer of zinc adhered to its surface. At present, the continuous galvanizing process is mainly used for production, that is, the coiled steel plate is continuously immersed in a galvanizing tank with molten zinc to make a galvanized steel plate;
• Alloyed galvanized steel plate. This kind of steel panel is also made by hot dip method, but it is heated to about 500℃ immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized sheet has good paint adhesion and weldability;
• Electro-galvanized steel plate. The galvanized steel panel manufactured by electroplating has good processability. However, the coating is thinner and its corrosion resistance is not as good as that of hot-dip galvanized panels;
• Single-sided galvanized steel and double-sided galvanized steel. Single-sided galvanized steel sheet, that is, a product that is galvanized on only one side. In terms of welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheet. In order to overcome the shortcomings of one side without galvanizing, there is another kind of galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized sheet;
• alloy, composite galvanized steel. It is an alloy made of zinc and other metals such as aluminum, lead, zinc, or even a composite plated steel plate. This kind of steel plate not only has excellent antirust performance, but also has good coating performance;
