Since the advent of galvanized steel sheet, it has been widely used in major industries such as construction and home appliances. Due to the continuous expansion of the scope of use, the formability and various properties of the product to the steel plate have been continuously improved, resulting in the fact that the aluminum-galvanized steel plate is superior to the hot-dip galvanized steel sheet in some properties. The galvanized steel sheet is an aluminum-zinc composite galvanized steel sheet made of cold-rolled hard steel sheets with various strengths and thickness specifications as the base material and hot-dip galvanized.

Hot-dip galvanized steel sheet has a history of 170 years. It mainly refers to the steel obtained by immersing cold-rolled steel strip or hot-rolled pickled steel strip in a plating solution with a zinc content of not less than 98% on a continuous production line. Among various hot-dip galvanized steel strips (plates), hot-dip galvanized steel strips (plates) account for the vast majority. Ordinary spangle (commonly known as ordinary spangle and large spangle) hot-dip galvanized steel strip (plate) is the basic variety of hot-dip galvanized steel strip (plate). It is a coating with obvious spangle shape formed by the free growth of zinc particles during the normal solidification process after hot-dip plating under the condition that the zinc solution contains antimony or lead.

At this stage, such raw materials have been widely used in the construction industry, while the application of automobiles, protective fences, anti-corrosion galvanized steel sheet, etc. has just begun to slow down. Traditional galvanized steel sheet is put on the market after simple anti-rust treatment, and the service life is only two years. The upgraded galvanized steel sheet raw material has replaced the traditional galvanized steel sheet. After a few kilograms of inspection and customer experience, its excellent characteristics have been verified. The actual relevant information can be queried according to the statistical data released by the manufacturer.

Galvanized steel sheet is a thick steel sheet with a layer of zinc on the surface. Due to the development of the economy, hot-dip galvanizing of thick steel plates is a way to prevent corrosion of thick steel plates. Galvanized steel sheet is used to make outdoor billboards because of their extra width and high cost performance. This product is built to last. In the natural environment of the suburbs, the standard hot-dip galvanized anti-rust treatment layer can be maintained for about 50 years without maintenance. In urban areas or coastal areas, the standard hot-dip galvanized anti-rust treatment layer can be maintained for 20 years without maintenance.

Everything has two sides, and galvanized steel sheet also has some disadvantages. Galvanized steel sheet of different materials have different disadvantages: if it is a tempered glass roof, the glass has good air permeability, which will inevitably lead to poor heat insulation performance; Single, unqualified; if it is a galvanized steel sheet with tile roof: its shade is not good enough, and the price is relatively high; however, skylights can be opened on the top, and tall windows can be designed around to help lighting and ventilation; if it is a sun panel, The cost of galvanized steel sheet is relatively high.
