Hot galvanized sheet is hot rolled galvanized sheet, cold galvanized sheet is cold rolled galvanized sheet. From the material point of view, the composition of the two galvanized sheets are basically similar, the difference is that the cold galvanized sheet is thinner than the hot galvanized sheet, the surface quality is better, the process is more complex, and the price is higher. From the process point of view, the steel is rolled by hot rolling, rolled into a certain thickness of the plate, such as the thickness of 10mm or so, if the user has no higher requirements for the surface of the plate, thickness, mechanical strength, it can be processed as a finished product, such as galvanized, sold directly, is a hot plate. If there are higher requirements for the plate, then the hot-rolled plate is sent to the cold rolling line for re-processing, after pickling, annealing, re-rolling and other processes, to get a thinner, smooth surface and better mechanical properties of the cold-rolled plate.
"Galvanized sheet 275g/㎡" means that the sum of the double-sided galvanized amount of the galvanized sheet per square meter area is 275 grams. The zinc flowers of hot dip galvanized steel plate are larger and more obvious, called "zinc flowers", and the zinc flowers are not fine enough, called "no zinc flowers".
What does having flowers and no flowers mean which is more expensive?
The zinc flowers of hot dip galvanized steel plate are larger and more obvious, called "zinc flowers", and the zinc flowers are finer and less obvious, called "no zinc flowers".
The hot plate substrate is generally made of zinc flowers, the cold plate substrate is generally made of no zinc flowers, and the cold plate is made of no zinc flowers, the surface is more smooth and smooth, the hardness is low, the elongation is high, the directional consistency is good, and the price is more expensive.
Galvanized sheet flowers and flowers are differentiated according to the surface state of galvanized sheet, generally weak eye will know, the surface has a pattern is flowers, there is no flowers. Flowers and no flowers have nothing to do with the material. The material depends on the substrate used for galvanizing, such as Q195, Q345, SPCC and so on. There is also no relationship between thickness and presence of zinc flowers.
There is a galvanized sheet, that is, the surface of the galvanized sheet is printed with a pattern, the appearance looks very bright, beautiful, and is generally used to make home appliance shells, buckets, and so on. There is no pattern on the surface of the flowerless galvanized sheet, which looks not as bright as the flowered galvanized sheet, dark color, and cold plate. There is no difference in performance, mainly in appearance.
There is a flower is the surface of the board has a pattern like a leaf, but also divided into small zinc flowers with large zinc flowers, no flowers is like aluminum plate, flat what pattern is not there
