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.

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.

Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other and forms an angle. It's the same type of steel, just called differently. It is a section steel specially used to make shelves. It has various shapes and many long holes for people to string screws. It is mainly used for personal shelves in shopping malls and factories.

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

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 .

1050 aluminum is often used as metal for chemical equipment and thin plate processing parts. 1050 aluminum alloy 2000 series aluminum plate represents 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, among which copper metal content is the highest, about 3-5%. The 2000 series and 7000 aluminum sheets belong to aviation aluminum and are not commonly used in conventional industries. There are fewer manufacturers of 2000 series aluminum sheets in my country. The quality can not be compared with foreign countries.

Corrugated board is also called profiled plate. It adopts color coated steel plate, galvanized sheet and other metal sheets to be rolled and cold-bent into various corrugated profiled plates. It is suitable for industrial and civil buildings, warehouses, special buildings, large-span Roof, wall and interior and exterior wall decoration of steel structure houses.

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.

Aluminum rod is a kind of aluminum product. The melting and casting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process. According to the different metal elements contained in aluminum rods, aluminum rods can be roughly divided into 8 categories. IntroductionAluminum (Al) is a light metal, and its compounds are widely distributed in nature. The resources of aluminum in the earth's crust are about 40-50 billion tons, second only to oxygen and silicon, ranking third. It is the largest category of metals among metal species.

A516GR60 is generally SA516GR60, which is equivalent to domestic SA516Gr70. SA516Gr60 belongs to the carbon steel plate for medium-sized stoves and low-temperature pressure vessels. It implements ASME standards. It was developed and produced by Wuyang Iron and Steel Co., Ltd. in 2006. It is widely used in petroleum, chemical, power station, boiler and other industries.
