Performance of SMC manhole cover 600x600 B125, pls let me introduce it:
Corrosion resistance and anti-aging, resistant to any harsh weather conditions.
The properties of the fiberglass themselves support the manhole covers with excellent temperature resistance(can be used at -50~150℃), chemical resistance (acid, alkali, salt, organic solvent, etc) and dimensional stability (very low coefficient of thermal expansion.)
Environmental-friendly. The raw materials used are halogen-free, SMC is non-toxic products. The reasonable structural design solves the noise problem caused by the impact between the cover and the frame.
