Introduction of gray iron manhole cover:
Our gray iron manhole cover is made of advanced sand casting technology. As an important part of urban transportation and drainage systems, gray iron manhole cover shows excellent compression resistance and corrosion resistance during long-term use, and can cope with various environmental and load conditions. These gray iron manhole covers are widely used in many fields such as municipal infrastructure, drainage systems, urban roads, etc.
Advantages of cast iron manhole covers:
1. Our cast iron manhole covers is made of corrosion-resistant and pressure-resistant cast iron materials, which can reduce maintenance and replacement frequency and reduce long-term costs.
2. In addition to standard casting, we also provide precision processing services such as CNC processing, so that cast iron manhole covers can accurately meet customer needs.
3. Cast iron manhole covers meet environmental protection standards and can reduce resource waste over a longer life cycle.
