Features of Baoding manhole covers:
The manhole cover has strong anti-theft performance: it is made of anti-theft alloy cast iron and non-professionals cannot destroy the manhole cover. The special anti-theft mechanism fundamentally solves the social problem of lost manhole covers.
Noise-free manhole covers: All manhole covers are processed by lathes to eliminate the noise caused by wheel rolling.
The manhole cover will not jump: The geometric size of the manhole circle is reasonably designed to ensure that the manhole cover does not flip and shift after a speeding vehicle passes through.
The manhole cover has a long service life: the product can be used normally for more than one year under open-air conditions.
The manhole cover is reasonably designed: it is easy to install and open for inspection and maintenance of underground pipeline facilities.
The manhole cover has beautiful appearance: light weight, large load-bearing capacity, clear casting pattern, excellent anti-slip performance, and pleasing colors.
