Analyze the hidden function of stainless steel manhole covers

Invisible manhole covers will not destroy the overall planning style, and because they use stainless steel materials, they will not corrode or rust due to long-term burial underground or rainwater. Because they are invisible manhole covers, their appearance is more aesthetically pleasing.

Cast iron manhole covers, however, rust easily and have a generally unattractive appearance, giving a very clumsy and ordinary feeling. Secondly, there is a difference in theft prevention. Traditional cast iron manhole covers are easy to remove and install, and they are directly exposed. Therefore, theft is very common, causing certain economic losses to relevant departments. However, invisible stainless steel manhole covers are different. Because this type of manhole cover is installed underground, it effectively prevents theft.

In terms of practicality: a traditional cast iron manhole cover is simply a large iron plate. While it has some practicality, it is slightly inferior to stainless steel manhole covers. Stainless steel manhole covers add an angle steel to the iron plate, ensuring easy installation while providing excellent tailoring for the stainless steel manhole cover.
