There are several surface treatment methods for sinks, what are the differences. China Stainless Steel Sink Company & Ningbo Afa Kitchen & Bathroom Co., Ltd. introduced five kinds of surface treatment methods for stainless steel sink in detail.

1.Pearl face

Some people also call pearl silver surface, matte surface, pearl matte surface and so on. It is made of chemical electrolyte for surface treatment (white is almost the same as electroplating). This surface treatment process is the simplest, with low technical content and low production cost. The price of manufactured goods is also lower. Currently, more than 90% of the country's nearly 2,000 manufacturers use this process for production. Many first-tier brands also use this process to capture the low-end market. However, the biggest drawback of this kind of surface is that it is not scratch-resistant, the surface is easy to scratch, and the coating will be severely peeled off. As a result, many large companies are gradually replacing this process with other processes.

2.Frosted surface

Also called pearl sand noodle. It uses small sand particles to hit the surface of the water tank uniformly and at high speed, so that the surface of the water tank uniformly forms a small number of small grooves (hard to see by human eyes), and has high hardness. The surface of the water tank is increased, which also increases its scratch resistance. This principle is equivalent to shot peening in machining. This treatment usually requires that the wall thickness of the board is not too thin. Generally, there are more water tanks for overall stretching.

  1. Brushing

Also called mercerized surface. It uses drawing equipment to repeatedly draw on the surface of the water tank (equivalent to the grinding machine processing in mechanical processing). Makes its surface traces of filaments, and the surface is very smooth. Visually has a strong inner peace. Since it is drawn directly on the surface of the sink, the requirements on the board are very high. The drawing of household boards sometimes has fine particles on the surface, which affects the appearance. Therefore, most drawing boards are imported.

4.Embossed surface

It is to press a regular pattern on the surface of the water tank, or directly use an embossed plate (equivalent to the pattern steel plate used on the pedestrian bridge), and then use pearl surface treatment for surface treatment. The relief surface also has good visual effects, but long-term oil fume in the kitchen can accumulate in the pattern and is difficult to clean.


Repeatedly polish the surface of the sink to make it look like a mirror. This treatment does not apply to ordinary families. It is easy to form scratches during use.
