I believe everyone is familiar with coated steel plates and color-coated plates. These two types of plates are widely used in the fields of home appliances and construction, but now more and more home appliance and construction manufacturers tend to use coated steel plates. What is the reason? Here is a detailed introduction to why coated steel sheets are better than color-coated sheets.
The basic concept of color-coated sheets: On a continuous unit, cold-rolled sheets or galvanized sheets are used as substrates. After surface pretreatment, one or more layers of liquid coating are applied by roller coating. The resulting sheet after baking and cooling is a color-coated sheet.
Color-coated sheets are easy to fade during use, and there are not many colors available for customers to choose from, so they are gradually replaced by coated steel sheets.
- High maintenance cost
Because the exterior of the color steel sheet is sprayed with paint, it is easy to fall off over time, affecting the appearance. Maintenance is usually required every 2 years.
- Poor sound insulation performance
The sound insulation effect of the color steel sheet is relatively poor, and its wind and pressure resistance are also relatively poor.
- Easy to rust
Because the color steel sheet is made by spraying the steel sheet on the surface, if the coating falls off, it is easy to rust inside.
The basic concept of coated steel sheet: In continuous The unit uses cold-rolled sheet or galvanized sheet as the substrate. After surface pretreatment, the color film is pasted on the substrate at high temperature. The steel plate formed after curing is the coated steel plate.
The coated steel plate does not require paint during the production process. Its stamping resistance, wear resistance, corrosion resistance and decorativeness are better than those of color-coated plates.
Since the coated steel plate is composed of film + steel plate, it has both the decorative performance of color film and the mechanical properties of steel plate. Compared with the single color of color-coated plate, the decorative effect of the coated steel plate is stronger.
The characteristics of the material used in the coated steel plate are that the color does not fade for a long time, the corrosion resistance is strong, and it is more conducive to the decoration of the outer wall.
In the application of home appliances, the advantages are also very prominent. It can meet the deep processing performance of the electrical housing. Stamping, bending, and drilling will not cause the surface color film to fall off, and it can meet the needs of various home appliance decorations.
I believe that from the above introduction, we can know why the coated steel plate is better than the color-coated plate.
