Compared with ordinary building boards, steel coils have stronger scratch resistance, and are not easy to leave scratches after being scratched by sharp objects, so they are often used to make home appliances and rolling shutter doors and windows. In addition, because of their good weather resistance , and easy to form, it is also often used as a substitute for wood.

2. How to polish the steel coil

1. When polishing the steel coil, you can use the mechanical polishing method. This method is generally manual, which is to make the uneven position of the steel coil flat. In the process, sandpaper and oilstone strips will be used. Mechanical polishing of the plate can improve the surface quality of the steel coil.

2. When polishing the steel coil, chemical polishing can also be used. This polishing method uses a chemical reaction to flatten the raised position of the steel coil. The biggest advantage is that there is no need to use too much in the process. Sophisticated equipment with good polishing effect.

3. Electrolytic polishing can also be used for steel coil polishing. Although the principle is very similar to that of chemical polishing, the polishing effect of electrolytic polishing is better in comparison, because this polishing method uses point solutions. The solution flattens the raised areas on the surface of the steel coil.
