SMC Composite Manhole Covers Benefits:
 

1.  Strength and high load capacity, meeting and exceeding EN 124 standard.

2.  Great performance to resist impact, compression and tension with low resonance noise.

3.  Light weight and cost saving.

1). More efficient transportation lowers the average cost.

2). Easy to handle by a single worker, cost being reduced either during installation or maintenance.

4.  Long service life without a geographical or environmental limitation.

1). More than 30 years.

2). Won't be damaged by extreme weather(either hot or cold) or corrosion.

5.  Safety concerned.

1). Dielectric, with no risk of either electricity or heat conduction.

2). Well sealed, preventing gas leaking.

3). Unique surface design, keeps pedestrians from sliping.

6.   Free design, either shape or color, logo or other information.
