High load-bearing capacity: The load-bearing capacity far exceeds that of other types of goods, and the load-bearing pressure is too high to prevent safety production accidents such as fractures and car falls.
The cast iron grate is the connecting part between the road surface and the sewer. The main function is to drain water. During rain, if the rain is too heavy, and some leaves or sand, or other household garbage is mixed in the water, cast iron grates will also provide a good isolation effect, which can better protect the smoothness of the sewer and ensure people's normal life.
The manufacturing process of casting manhole covers consists of five steps: pattern making, mold preparation, melting/pouring, cooling and finishing.
