When installing, be sure to check its thickness to avoid being deceived by others. In addition, the wall thickness of the riser should be above 0.7mm, because the installation of the riser is relatively complex, so it is normal for it to be thinner than the main pipe, but it is absolutely not acceptable if it is below 0.7.

If there is rust on the stainless steel guardrail, it cannot be sanded off with sandpaper at this time. This will not only damage the appearance of stainless steel, but also damage the protective film on the surface of stainless steel, which will lead to more rust in the future. The correct method is to go to the stainless steel market to buy smooth water, or tell the merchants that it is specifically used to remove stainless steel rust, and they will know. If you want to completely eliminate rust, it would be even better to polish wax on it once.
