Speaking of coated steel plates, they are steel plates with decorative colored films. Nowadays, coated steel plates are widely used, such as hospitals, stations, modern factories, logistics warehouses, large complexes and other large industrial building roof construction and factory renovation projects.
In home appliances such as refrigerators, washing machines, water heaters, rice cookers, etc., many shells are also using coated steel plates.
This steel plate is composed of a combination of substrate + color film. Different usage scenarios require different substrates. The introduction of the substrate of the coated steel plate is now shared by the editor and everyone:
01 Hot-dip galvanized steel plate
This substrate has excellent impact performance, excellent elongation and yield value. The coated steel plate made of this substrate has been well evaluated in: construction, decoration, and other industries
02 Hot-dip aluminum-zinc steel plate
The process of this substrate is basically similar to that of hot-dip galvanized steel plate. The difference lies in the different zinc content composition on the surface, and the surface zinc phenomenon is also very different. There is basically no difference in other aspects. The weather resistance and life are better than galvanized steel plate
03 Aluminum plate
The best advantage of aluminum plate is that it is used in special industries. Because the price itself is very high, the cost alone is also a considerable expense, so it is only selected by special industries: refrigeration, heating, disinfection, sterilization and other industries. Impact performance: excellent, can be impacted and bent in visible and invisible ways
04 Cold-rolled sheet
Cold-rolled sheet is a steel sheet that has not been annealed, and is also the predecessor of galvanized steel sheet and aluminum-zinc steel sheet. This steel sheet has very low impact performance, high material hardness, low yield value and elongation, and excellent welding performance
