The stainless steel sinks in the kitchen are usually divided according to the structure, which can be divided into zero radius corner sinks and micro radius corner sinks (we also call them zero-r sink and micro-r sink for short).
Note that the zero radius corner and round radius corner here refer to the welds on the four sides of the inner bowl, not the exterior corners of the sink. The advantage of the zero-r sink is that the process is relatively simple, and the finished product looks angular and makes people feel that it is relatively high-end
However, the shortcomings of zero-r sinks are unacceptable relatively. Because the four sides of the sink bowl are all at a right angle of 90 degrees, it is difficult to clean them in place.
Therefore, it is easy to collect dirt when used for a long time, and it is very difficult to clean up. In particular, some oil stains adhere to the weld seam, it is easy to turn yellow, corrode the weld road, and cause the weld seam to rust after a long time.
At that time, unless a special welding circuit brightener is used to clean the welding circuit, it will be difficult to eliminate it. So many consumers have slowly lost interest in the zero-r sink. Then, a gold R10 round corner sink appeared on the market.
