Why selling well for the cast iron gully grate

Cast iron grate is generally an important role in the sanitation city. Generally speaking, it is mainly a circular nodolar casting iron rainwater grate. The design attaches great importance to beauty, environmental protection, service life and other factors, so it is favored by the city.
In the completion of the city, drainage system should also be a big problem, almost community, the roadside will appear all kinds of rainwater grate, and the current construction in the new community, rainwater grate is more and more unified, basically will choose new rainwater grate-nodular casting iron rainwater grate, now choose to use nodular casting iron rain grate and give up the traditional rainwater grate. Cast iron grate is a kind of nodular casting iron product. Nodular iron obtains spherical graphite through globtization and gestation treatment, which effectively improves the mechanical performance of cast iron, especially the plasticity and toughness, so as to obtain higher strength than carbon steel.

 

 

The spherical graphite microstructure of cast iron grate is better than cast steel for reducing vibration ability and thus reducing stress.
One important reason in choosing the casting iron grate is that nodular iron is less expensive than cast steel, its cost makes this material more popular, has high casting efficiency, and also reduces processing costs.
