Titanium plates can have different surface states, depending on production and processing requirements as well as application needs. Here are some common surface states of titanium plates:

1. Hot rolled surface: Hot rolling is a common method of manufacturing titanium plates, which typically have a rough surface and require subsequent processing and surface treatment to meet specific requirements.

2. Cold rolled surface: Cold rolling is achieved by rolling titanium plates at room temperature to obtain smoother and more uniform surface quality. Cold rolled sheets typically have a smoother surface and are suitable for applications that require higher surface quality.

3. Pickled surface: Pickling is a surface treatment method that can remove oxides, dirt, and poor surfaces from the surface of titanium plates. This can improve the appearance and corrosion resistance of the titanium plate.

4. Polishing surface: Polishing is the process of mechanically or chemically treating the surface of a titanium plate to give it a highly smooth and reflective appearance. Polishing surfaces is commonly used for applications that require a refined appearance.

5. Sandblasting surface: Sandblasting is achieved by spraying sand particles on the surface of titanium plates to obtain a uniform rough surface, in order to increase surface friction and wear resistance. This type of surface is typically used for applications that require anti slip or increased surface roughness.

6. Anodizing surface: Anodizing is a surface treatment method that can form an oxide layer on the surface of titanium plates, enhancing their corrosion resistance and hardness. This type of processing is typically used for specific electronic and chemical applications.

7. Each surface state has different characteristics and application fields. Choosing the appropriate surface condition depends on your specific needs, such as appearance, corrosion resistance, friction performance, and assembly requirements. Before purchasing titanium plates, it is recommended to discuss your needs with the material supplier or manufacturer to ensure the selection of a suitable surface condition.
