Galvanized steel is carbon steel coated with zinc. The most common galvanizing method is the hot-dip process. The hot dip process involves immersing carbon steel in a molten zinc bath (approximately 680 degrees Fahrenheit). When the material is removed from the zinc bath and cooled, it reacts with oxygen in the air. This reaction causes zinc to become part of the steel (iron-zinc alloy bond). The new surface finish seems to have a crystalline finish or a bright finish.
Although this is the most common form of galvanizing, because the thickness of the final product is not easy to control, it is usually used for previously manufactured steel. Another method of galvanizing process is continuous galvanizing.
After continuous galvanizing passes through the zinc bath, galvanizing will be performed on the surface of the continuous steel strip (coil). The coil runs at about 600 feet per minute. When the coil leaves the zinc bath, it takes away an extra layer of molten zinc. Use high-pressure air (air knife) to remove excess zinc to form the desired thickness. The material is then allowed to cool and form a shiny finish. Skip galvanized steel sheet and continuous galvanizing can control the thickness more accurately, and is usually used for steel that has not been manufactured. As the thickness of the coating increases, the risk of losing some of the coating during manufacturing or forming increases.
One: Waterproof paper. Waterproof paper is wrapped in the surface of a galvanized roll. Its main function is to prevent galvanized volume moisture, and avoid water vapor into the volume, then influence of hot dip galvanized coil surface. Such as zinc oxide layer when water vapor, can appear on the zinc spend turned white, affect beauty and using. This layer is necessary for the waterproof.
Two: Galvanized steel layer. It’s out of waterproof paper. During the transportation progress, it’s very easy to hit. This layer is to prevent the scratch on the surface.
Three: Edge Protection layer. It is on the both sides of the roll, and made of iron. It’s mainly to protect the edge of galvanized roll. It’s very important, if the edge of galvanized steel coil wasn’t protected, might affect the deep processing, and even damage the machine.
Four: Straps. It is used to fix the waterproof paper and galvanized iron packaging, avoid the iron fall off. For galvanized roll with the width of 1000mm to 1500mm, it should be 8 straps and transverse 4 pieces, vertical 4 pieces. It’s the best way to tighten the rolls.
Five: Tags/Marks. Mill tags will be stick on every coils outside the packages. Including: name of commodity, grade, gross weight, net weight, roll number, and information of the mill, supplier information, etc. It’s will be helpful for clients to find the right rolls against the packing list.
