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 .

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.

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.

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.

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.

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.

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.

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.

As an vital metallic material, carbon metal performs an vital position in many fields with its incredible performance.In the development industry, carbon metal is one of the key substances for constructing secure structures.

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
