Safety Upgrade! New Composite Manhole Covers Protect Urban Underground Pipelines

1.High Visibility & Anti-slip Performance

The bright yellow exterior delivers outstanding warning effects, enabling quick location of pipelines even on rainy and foggy days. The raised anti-slip dots on the surface effectively prevent slips on snowy or wet ground, protecting pedestrians and maintenance staff.

2.Excellent Durability & Long Service Life

Made of SMC/BMC glass fiber reinforced resin, the covers resist acid, alkali and UV aging. They won't crack or deform easily even in humid, saline and other harsh environments, and boast a far longer lifespan than traditional cast iron manhole covers, cutting long-term maintenance costs greatly.

3.Lightweight & Easy Operation

Weighing only one-third to one-half of conventional cast iron covers of the same size, they can be easily lifted by a single person, greatly improving the efficiency of inspection and maintenance work.
