Galvanized sheet is a kind of steel sheet, and it can be said that many of the steel sheets are galvanized sheet. Galvanized sheet is a kind of steel plate with excellent anti-corrosion performance created according to 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. are used to make galvanized sheet. What is galvanized sheetGalvanized sheet refers to a steel sheet plated with a layer of zinc on the surface.

Recently, the color roll market has shown a booming trend, and its demand is growing in many areas, which is inseparable from its continuous improvement of production technology.Substrate preparation: The substrate of the color coated coil is usually cold-rolled strip steel or hot-rolled strip steel, and some will also use hot galvanized sheet, hot aluminum plated zinc plate, electrogalvanized sheet, etc.

Aluminum plate refers to the aluminum material with a thickness of more than 0.2mm to less than 500mm, a width of more than 200mm, and a length of less than 16m. With the progress of large equipment, there are more aluminum plates that can be as wide as 600mm).Aluminum plate refers to a rectangular plate processed by rolling aluminum ingots, divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium-thick aluminum plate, patterned aluminum plateMaintainThe specific cleaning steps of the aluminum plate are as follows:1.

Roofing sheet is a profiled plate processed by a series of processes such as rolling and cold bending of color steel plates into various wave shapes.It not only has the excellent decorative performance of traditional clay tiles, but also has the excellent performance of modern metal tiles. It is light, strong and durable. It is the current mainstream roofing material.

Color-coated coil is based on hot-dip galvanized sheet, hot-dip galvanized sheet, electro-galvanized sheet, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied on the surface, and then A product that is baked and cured.

Galvanized coil, a thin steel sheet that is dipped in a bath of molten zinc to adhere a layer of zinc 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.

Aluminum tube refers to a metal tubular material that is hollow along its entire longitudinal length through extrusion processing of pure aluminum or aluminum alloy. There can be one or more closed through holes, the wall thickness and cross-section are uniform, and they are delivered in straight lines or in rolls. Widely used in automobiles, ships, aviation, electrical appliances, agriculture, electromechanical, home furnishing and other industries.

The production process of galvanized coil mainly has two kinds of hot dip galvanizing and electric galvanizing, the following is a detailed introduction:Hot-dip galvanizing processSurface pretreatment: First of all, the surface treatment of the steel plate, including cleaning, oil removal and rust removal processes, to ensure that the surface of the steel plate is clean and smooth, to provide a good foundation for subsequent galvanized, enhance the adhesion of the galvanized layer 1.Pickling and phosphating: pickling is to soak the steel plate in the acid solution to remove the surface oxide a

And cold-rolled coil (annealed state): it is obtained by bell-type annealing before the chilled coil is rolled. After annealing, its work hardening phenomenon, that is, the decrease in yield strength is close to that before cold rolling.Definition of cold rolled coilCold-rolled coils are made of hot-rolled coils, which are rolled at room temperature below the recrystallization temperature, including plates and coils.

The material of carbon steel plate is plain carbon steel or carbon steel, which is a steel with a carbon content of less than 2.11% and no metal elements intentionally added. In addition to carbon, it also contains a small amount of sulfur, silicon, phosphorus, manganese and other elements .
