1. Anti theft: stainless steel concealed manhole cover has less surface exposure because its production process and installation method are embedded in the manhole cover. When installing this invisible stainless steel manhole cover, the stainless steel manhole cover will be hidden under the road surface, so the function that is not easy to be found is just to prevent theft.

2. Rust prevention: Stainless steel manhole cover The production is made of stainless steel plate. Before the production of stainless steel manhole cover, the manufacturer of stainless steel manhole cover will inform the customer in advance of the material selection required. In stainless steel, most of the manufacturer's 304316 materials. 304 and 316 materials have strong rust resistance, and also have certain weather resistance and heat resistance. When the stainless steel manhole cover is buried underground for a long time, it will not corrode due to the weather. At the same time, due to the high temperature of the ground, its strong heat resistance will not cause any problems.

　　3。 Aesthetics: The places where stainless steel manhole covers are used are basically mall sidewalks, squares, pedestrian streets, etc. These places have high aesthetic requirements, because the stainless steel manhole cover is embedded under the floor tile and made of stainless steel. After installing the manhole cover, we can only see the corner of the manhole cover. Other places form a whole with the road surface, and the aesthetic performance is extremely high.

In addition to the above anti-theft, rust prevention and beauty, stainless steel manhole covers are also very practical, simple and convenient to install, and do not need to be removed by construction personnel. This requires too much effort.
