4. Feature Advantage
1.Attractive appearance:Simple outline.silver colour,and modern.
2.Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron.
3.Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free.
4.Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft,safety,and convenient opening.
5.Saving investment:With large span,the cost is lower than that of cast iron when under heavy load.And the replacement expenses in case of theft and crushing will be saved.
6.High strength:With strength:With strength and toughness far higher than those of cast iron,it can be used in the environment with large span and heavy load,such as the wharf and the airport.
7.Many specifications available: The requirement of different environments,loads,spans,sizes and shapes can be satisfied.
