Galvanized steel.

La description

    Based on a variety of hot galvanized steel strength and thickness of cold-rolled steel sheet for the substrate, a layer of double-sided hot-dip galvanized steel sheet pre-coated Al-Zn income, the percentage of the mass of the coating composition 55% Al, 43.5% Zn and 1.5% Si, combines physical protection and high durability and electrochemical protection features of Al and Zn. In addition, the surface was bright silver-taek and rules with high decorative pattern, and having a sense of floating Acts projections

    Hot galvanized alloy is developed on the basis of heat aluminum and galvanized technology on both aluminum products with a good weather resistance, heat resistance to oxidation, but also with a galvanized steel product fine electrochemical protection, is not easy to make incisions and scratches rust corrosion. its

The main advantages are as follows：
(1) smooth surface, excellent resistance to atmospheric corrosion, its corrosion life of 2-6 times higher than the galvanized steel sheet;
(2) has good heat resistance to oxidation at 300 ℃ long-term change color, about 500 ℃ long-term use, has good water, soil corrosion resistance, corrosion resistance superior to its water and hot galvanized plate aluminum plate, soil corrosion resistance than hot galvanized plate, is to produce automobile mufflers, exhaust pipes, an ideal material for grain dryers,water heaters and other corrosion resistant device; in addition, heat-reflective rate products 75% galvanized sheet is 2 times;
(3) having excellent coating properties and good processability. The combination of strong organic material, is far the best choose color organic coated steel substrate. Workability andweldability and hot galvanized plate similar and can be cold bending, stamping and other processing, and have a good look. Further, since the aluminum is smaller than the proportion of zinc, aluminum and zinc alloy plating proportion is only 3.7kg / dm3, while the proportion of zinc is 7.1kg / dm3, and therefore under the same coating thickness, low weightaluminum-zinc alloy, which greatly saves the high price of the metal plating

The main purpose of hot galvanized steel :( Applications: demanding industries with galvanized sheet)
Construction: civil and industrial building roofs, exterior walls, garage doors, fences, shutters
Appliance industry: outer oven, explosion-proof strip, air conditioning and ventilation systems cover, solar water heaters, electrical components
Automotive: car muffler, exhaust pipe and catalytic converter heat shield, the bottom of the car body parts, road signs
Industrial Instrumentation: cabinet, industrial freezers, vending machines
