Hot dip galvanized steel coil
Hot dip galvanized steel coil, also known as hot-dip galvanized coil, takes the steel coil as the base material and achieves the purpose of rust prevention by hot-dip galvanizing. Hot dip galvanized steel coil, a kind of steel material coated with zinc. Galvanized coil is the predecessor of galvanized sheet. It can be cut into plates by using equipment. It can be put on the shelf by forklift or aerial crane, and then transmitted, flattened and sheared by equipment. The width is the standard width of one meter, one meter five, one meter five, length is optional.
Main uses of hot-dip galvanized steel coil: the color coated steel sheet with galvanized steel coil as the base material is used. In addition to zinc protection, the organic coating on the zinc layer plays a covering and isolating role, which can prevent the steel plate from rusting, and its service life is longer than that of galvanized steel sheet. According to the introduction, the service life of coated steel sheet is 50% longer than that of galvanized steel sheet. In different areas, the service life of hot-dip galvanized steel coil with the same amount of zinc plating will be very different. For example, in industrial areas or coastal areas, due to the effect of sulfur dioxide gas or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating will be corroded quickly and its service life will be reduced if it is soaked by rain for a long time, or if the temperature difference between day and night is too large and the condensation is easy. The coated hot-dip galvanized steel coil has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry and so on. It has played a good role in replacing wood with steel, efficient construction, energy saving and pollution prevention. Buildings or workshops made of steel plates made of color coated hot-dip galvanized steel coils often have a longer service life when washed by rain, otherwise, they will be affected by the action of sulfur dioxide gas, salt and dust.
As the predecessor of hot-dip galvanized steel sheet, the output of hot-dip galvanized steel coil is directly related to the output of hot-dip galvanized steel sheet. In recent years, the consumption of galvanized steel sheet in China is far greater than that of production, resulting in the need for a large number of imported galvanized steel sheet, which makes the price of galvanized sheet in the steel market continue to rise.
