弥补了铸铁、水泥类井盖的不足，从防盗、环境保护、安全、便利美观、使用年限等观点出发，具有共同的优越性质，已成为城市道路、公共等部分的五金产品。 Stainless steel manhole covers make up for the shortcomings of cast iron and cement manhole covers . From the perspectives of anti-theft, environmental protection, safety, convenience and beauty, and useful life, they have common superiority and have become hardware products for urban roads and public parts. So, what are the advantages of stainless steel manhole covers?
I. Anti-theft property: Compared with other raw material manhole covers, stainless steel manhole covers are more sturdy, have smaller joint gaps, and are generally difficult to pry open, and have strong anti-theft functions.
2. Safety: The manhole cover must not only prevent theft, but also bear the responsibility for the safety of the pipeline construction personnel, because the stainless steel manhole cover is selected so that the stainless steel manhole cover does not smash even when it reaches a damaging load, to avoid all aspects of the formation of drops.
3. High precision: The stainless steel manhole cover is molded, and the gap between the cover and the joint seam is small, which overcomes the problem of "running, jumping and ringing" of the original manhole cover, and greatly improves the road traffic function and driving comfort.
4. Convenient and beautiful: The stainless steel manhole cover is only two-thirds of the cast iron manhole cover , which brings great convenience to the installation and inspection. The invisible manhole cover can also be used, so that the beauty of the entire environment is not damaged. It can be classified and colored according to the occupation part, which is convenient for classification management.
Advantages of using stainless steel manhole covers:
First of all, when the manhole cover is used, there will often be deformation and short use time. However, if a stainless steel manhole cover is used, it will have a very strong ability to resist compression, bending and impact, and it also has strong toughness. The manhole cover will not be broken for a long time, so it can greatly prevent the phenomenon of urban black holes.
Secondly, the attractive place is that this manhole cover has a beautiful pattern on the surface, which can beautify the environment.
It can be seen that stainless steel manhole covers will be used in more and more places in the future.
