square composite material heavy duty manhole cover

Features of 800*800 square stainless steel manhole cover:

1. Anti-theft: Compared with other material manhole covers, the 800*800 square stainless steel manhole covers are more firm, with small joint gaps, difficult to pry open with ordinary tools, and strong anti-theft performance.

2. Safety: 800*800 square stainless steel manhole cover should not only prevent theft, but also take responsibility for the safety of pipeline construction personnel. Due to the use of steel support, the stainless steel manhole cover will not be crushed even if it reaches destructive loads to prevent all aspects caused by falling harm.

3. High precision: The 800*800 square stainless steel manhole cover is molded with a small gap between the cover and the seat, which overcomes the "running, jumping, and sounding" problems of the original manhole cover, and greatly improves road traffic performance and driving comfort.

4. Convenient and beautiful: The 800*800 square stainless steel manhole cover is only two-thirds of the cast iron manhole cover, which brings great convenience to installation and inspection. An recessed manhole cover can also be used, so that the beauty of the overall environment is not destroyed. It can be classified and colored according to industry sectors, which is convenient for classification management.

5. Corrosion resistance: The manhole cover is open all year round and requires high corrosion resistance. The 800*800 square stainless steel manhole cover not only has good moisture resistance, acid and alkali resistance, but also anti-aging, and has a long service life.
