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.

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.

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 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

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.

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.

Galvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Cold galvanized steel pipes have been banned, and the latter has been advocated by the state for temporary use. In the 1960s and 1970s, developed countries began to develop new types of pipes, and have banned galvanized pipes. China's Ministry of Construction and other four ministries and commissions also issued a document explicitly banning galvanized pipes as water supply pipes from 2000.

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.

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.
