Galvanized/Galvalume steel coil, also known as galvanized coil, is a kind of galvanized coil product.
Galvanized coil, a steel material coated with zinc on its surface. The galvanized coil is the predecessor of the galvanized sheet. The equipment is used to cut the galvanized coil into a sheet. The galvanized coil is placed on the shelf with a forklift or a crane and then transported, flattened and sheared by the equipment. The width is standard width one meter, one meter two or five, one meter five or three, and the length is arbitrary.
The use of galvanized coil: The coated steel plate 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 , Has played a good role in replacing steel with steel, efficient construction, energy saving, pollution prevention and so on. In addition to zinc protection, the color-coated steel plate using galvanized steel plate as the substrate, the organic coating on the zinc layer plays a role of covering isolation, which can prevent the steel plate from rusting, and the service life is longer than the galvanized steel plate. According to the introduction coating The service life of steel plate is 50% longer than galvanized steel plate. However, in different regions and different parts of use, using the same galvanized amount, the same kind of paint, the same coating thickness of the color coated board, its service life will be very different. For example, in industrial areas or coastal areas, due to the effects 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 wetted by rain for a long time, or the part where the temperature difference between day and night is too large and easy to condense will be corroded quickly, and the service life will be reduced. Buildings or workshops made of colored coated steel plates often have a long service life when they are washed by rain. Otherwise, they will be affected by the effects of sulfur dioxide gas, salt, and dust. Therefore, when designing, the greater the inclination of the roof, the less likely to accumulate dust and other dirt, and the longer the service life; those areas or parts that are not frequently washed by rain should be washed regularly with water.
