Who are you? I just made a flat one in Tianjin, and it cost about 2,000 yuan to calculate another 20 stents.
The width of the fence is less than or equal to 10cm, (to prevent children from drilling in and out). The width of the protruding wall is less than 2 cm, preferably negative, in order to prevent thieves from stepping on the ladder to steal the upper floor.
The invisible one looks better, and the practicality of stainless steel will be better, so it is recommended to choose the latter.
Yes It depends on personal choice.
Hope it can help you, if your problem is solved, please click to adopt, thanks. >>>More

There is no definite answer, it is determined by the materials used, the production process, the use environment and daily maintenance. As mentioned upstairs, it will not be a problem to use good stainless steel materials for hundreds of years or even longer.
