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.

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.

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

Galvanized steel sheet is a high-quality building material widely used in industry and construction fields. By coating a layer of anti-corrosion zinc on the surface of the steel plate, galvanized steel plates have excellent advantages over ordinary steel plates.Galvanized steel plate is a welded steel plate with a hot-dip or electroplated zinc layer on the surface.

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 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 .

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.

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.

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.

Channel steel is a carbon structural steel for manufacturing and machinery. It is a section steel with a complex section, and its cross-sectional shape is groove-shaped. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have good welding, riveting performance and comprehensive mechanical performance.The raw material billet for producing channel steel is carbon-structured steel or low-alloy steel billet with a carbon content not exceeding 0.25%.
