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.

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%.

Aluminum profiles are an vital fabric for current enterprise and life, exerting impact with special overall performance and vast application.Product characteristics1.Lightweight and excessive strength: The density of aluminum is about 2.7g/cm³, which is 1/3 of steel. It is effortless to lift and install.

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.

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.

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.

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

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.

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 .
