This galvanized steel sheet is manufactured by electroplating with a galvanized sheet with good processability. However, the coating is thin, and the corrosion resistance is not as good as that of the hot-dip galvanized sheet; single-side plating and double-sided galvanized steel sheet. Single-sided galvanized steel, ie galvanized on one side only. In welding, painting, anti-rust treatment, processing, etc., has better adaptability than double-sided galvanized sheet. In order to overcome the disadvantages of uncoated zinc on one side, there is another galvanized sheet coated with a thin layer of zinc on the other side, ie, a double-sided differential galvanized sheet, an alloy, and a composite galvanized steel sheet. It is made of zinc and other metals such as aluminum, lead, zinc and other alloyed or even composite plated steel. This steel sheet has both excellent rust resistance and good coating performance.
The surface of the galvanized steel sheet is uniquely smooth, flat and gorgeous star flower, the basic color is silver white. The coating composition consists of 55% aluminum and 43.4% zinc and 1.6% silicon, respectively, in weight ratio. The production process of the galvanized steel sheet is similar to that of the galvanized steel sheet and the aluminized sheet, and is a continuous melt coating process. The 55% aluminum-zinc alloy-coated galvanized steel sheet has superior corrosion resistance when compared to the same thickness of galvanized steel sheet when both sides are exposed to the same environment. The 55% aluminum-zinc alloy coated galvanized steel sheet not only has good corrosion resistance, but the color coated product has excellent adhesion and flexibility.
Hot-dip galvanized steel (commonly known as galvanized iron), galvanized steel, single-sided or double-difference thick galvanized steel, alloy composite galvanized steel, in addition to the above, in addition to the color galvanized steel (popularly known as Color plate), printing coating galvanized steel, PVC laminated galvanized steel and so on. In addition, galvanized steel sheets can be divided into general-purpose, roof-topped, architectural-outer-board, structural-use, tile-raising-sheet, drawing, and deep-drawing applications.
The galvanized sheet is an aluminum-zinc alloy structure consisting of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600°C. The entire structure consists of aluminum-iron-silicon-zinc to form a dense quaternary crystal. An alloy plated steel plate. Corrosion resistance The corrosion resistance of galvanized steel coils is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide that prevents the corrosive material from further corroding the interior. Aluminum-zinc alloy steel plate has good heat resistance, can withstand high temperatures of more than 300 degrees Celsius, and is very similar to the high temperature oxidation resistance of aluminum-plated steel.
