GNEE galvanized coil construction and light industrial demand is the main market for galvanized sheet, its demand accounts for about 30% of galvanized sheet. According to the national economic development rate and the previous consumption base to calculate, its demand in the first half of the year in about 4 million tons, equivalent to 180,000 tons of refined zinc consumption. There are also from the home appliance industry on the consumption of galvanized steel, air conditioning is the main consumption of galvanized steel products.
Air conditioning indoor unit of the back plate, cabinet back plate, internal parts, outdoor unit shell and the interior are galvanized sheet manufacturing, an average of an air conditioner needs to consume 22 kg of galvanized sheet. In addition, each washing machine consumes 8 kg of galvanized sheet and each refrigerator consumes 3 kg of galvanized sheet.
I don't know if you have heard of the word galvanized, but it is a new type of metal material, which is a very thin steel sheet put into the liquefied zinc, and by dipping it, the steel and the liquid zinc undergo a chemical reaction, so that a thin layer of zinc is attached to the surface of the steel. Galvanized coil is the same thing, of course, is put into the rolls of steel plate soaked plus a made.
Single-sided and double-sided galvanized steel coils. Single-sided galvanized steel coil, that is, only in one side of the galvanized products. It has better adaptability than double-sided galvanized steel coil in terms of welding, painting, anti-rust treatment and processing. In order to overcome the shortcomings of single-sided uncoated zinc, there is a galvanized coil coated with a thin layer of zinc on the other side of the galvanized coil, i.e., double-sided differential galvanized coil; alloy, composite galvanized steel coil. It is made of zinc and other metals such as lead, zinc alloy or even composite galvanized steel coil.
This kind of steel coil has both excellent rustproof performance and good painting performance. Galvanized coil surface on the surface of the steel coated with a layer of zinc, in fact, but also because the steel plate is easily oxidized by the water in the air and other oxides, and thus corroded, coated with a layer of zinc in fact, but also to better protect the steel. Galvanized coils have two major advantages, one is adhesion and one is weldability. It is due to these two advantages that it is widely used in construction, industry, automobile industry as well as commerce. Another important characteristic is corrosion resistance, which can produce good results in the manufacture of appliance housings.
