Feathurs:
1.Stainless steel has different grades, correspond to different hardness, thermoplastic, plasticity and weldability. If you don't understand, you can tell us your requirements.
2. Stainless steel can be customized for different surfaces, and different surfaces have different applications. For example, 8k mirrors are generally used for decoration.
3.We have more than 30 years of experience in this industry and believe that we can satisfy any demand for stainless steel raw materials.
There are six types of stainless steel surface treatments, namely mirror treatment, sandblasting treatment, chemical treatment, surface coloring, surface drawing treatment, and spray coating. When carrying out construction, choose the appropriate treatment method according to the needs, avoid a lot of unnecessary waste while achieving the effect, and save a lot of time and energy.
Mirror treatment: Polishing the outer layer of stainless steel can be divided into two methods: physical and chemical. You can also do partial polishing on the surface, which can make stainless steel more concise, high-end, fashionable and advanced.
Sandblasting treatment: It mainly uses the power obtained from air compression to apply spray material to the outer layer that needs to be treated at high speed. It can make the shape of the outer layer change.
Chemical treatment: It mainly uses chemistry and electricity to form a stable compound on the outer layer of stainless steel. For example, the most common type of electroplating is chemical treatment.
