Compared with the traditional flat cast iron manhole cover , the stainless steel invisible manhole cover has a concave shape and can be filled with various patterns to make it level with the ground. First of all, I would like to remind everyone to know what problems to pay attention to when constructing stainless steel manhole covers .
This new type of manhole cover adopts German technology. The manhole cover frame is made of nodular cast iron. The load standard is 20-40 tons. The filling manhole cover can be equipped with safety locks. It can be used for secondary paving. The decorative materials are integrated with the colored bricks and marble on the square, the residence, the leisure community and the sidewalk to play a role in beautifying the environment and set off different humanistic environments and place atmosphere.
Stainless steel invisible manhole cover is also called filled manhole cover. It is designed to meet the load requirements of heavy and light, and provides high standards of product security. Different reinforcing materials are used according to different parts of the manhole cover, and the surface layer is made of quartz sand particles as a filling material, which has good abrasion resistance. The ultraviolet absorbing agent is added to improve the anti-aging effect of the manhole cover. The structure layer can give full play to the characteristics of continuous fibers, so that the manhole cover does not contain any steel bars, has a higher bearing capacity and a longer service life, and is more competitive in the market. Play a decorative role.
Product features: High carrying capacity: higher than national testing standards. No regeneration value: long-term stable and reliable quality. Strong appearance texture: Can be made into various relief textures.
One kind of manhole cover has one characteristic. There is a big difference between stainless steel invisible manhole cover and cast iron invisible manhole cover.
