The multiple surface processing of stainless steel broadens its application fields-different surface processing makes the surface of stainless steel different, making it unique in its application.
In the field of construction applications, the surface processing of stainless steel is important for many reasons.
The corrosive environment requires a smooth surface because the surface is smooth and not easy to foul. The deposit of dirt will rust stainless steel and even cause corrosion.
In a spacious hall, stainless steel is the most commonly used material for elevator decorative panels. Although the fingerprints on the surface can be wiped off, it affects the appearance, so it is best to choose a suitable surface to prevent fingerprints from being left.
Sanitary conditions are very important to many industries, such as food processing, catering, brewing, and chemicals. In these applications, the surface must be easy to clean every day, and chemical cleaning agents are often used.
Stainless steel is the best material in this regard. In public places, the surface of stainless steel is often scribbled. However, one of its important features is that they can be washed away. This is a significant feature of stainless steel over aluminum. It is easy to leave marks on the surface of aluminum, which is often difficult to remove. When cleaning the surface of stainless steel, you should follow the lines of stainless steel, because some of the lines processed on the surface are unidirectional.
Stainless steel is most suitable for hospitals or other areas where sanitary conditions are critical, such as food processing, catering, brewing and chemical engineering. This is not only because it is easy to clean every day, and sometimes chemical cleaning agents are used, but also because it is not easy to breed bacteria . Tests show that the performance of stainless steel in this respect is the same as that of glass and ceramics.
1. The natural appearance of stainless steel
Stainless steel gives a natural, firm and beautiful feeling, and its natural color softly reflects the color of the surrounding environment.
2. The basic types of surface processing
There are roughly five types of surface processing that can be used for stainless steel, and they can be combined to transform into more final products.
The five categories are: rolling surface processing, mechanical surface processing, chemical surface processing, texture surface processing and color surface processing.
There are also some special surface processing, but no matter which surface processing is specified, the following steps should be followed:
① Negotiate the required surface processing together with the manufacturer, and it is best to prepare a sample as the standard for mass production in the future.
②When using a large area (such as a composite board, you must ensure that the base coil or coil used is the same batch.
③In many construction applications, such as inside elevators, although the fingerprints can be wiped off, they are not beautiful. If you choose a cloth surface, it is not so obvious. Mirror stainless steel must not be used in these sensitive places.
④ The production process should be considered when selecting the surface processing. For example, in order to remove the weld bead, the weld may have to be ground and the original surface processing must be restored.
The tread plate is difficult or even unable to meet this requirement.
⑤ For some surface processing, grinding or polishing lines are directional, which is called unidirectional. If the lines are vertical instead of horizontal when used, dirt will not stick to it easily and it will be easy to clean.
⑥ No matter what kind of finishing is used, it needs to increase the process steps, so it will increase the cost. Therefore, be careful when choosing the surface processing.
Therefore, architects, designers, manufacturers and other relevant personnel need to understand the surface processing of stainless steel. Through friendly cooperation and mutual exchanges between each other, the desired effect will surely be obtained.
⑦According to our experience, we do not recommend using alumina as an abrasive, unless you are very careful during use. It is best to use silicon carbide abrasives.
