Sand holes are typically caused by improper compaction of molding sand or moisture content imbalance. Our automated sand treatment system ensures consistent quality and minimizes such defects.

What are the features of stainless steel manhole covers?

Stainless steel covers offer superior corrosion resistance, hygiene, and longevity. They are ideal for coastal areas, food processing plants, and high-moisture environments.

Why are cast iron grates selling well?

Cast iron grates are durable, cost-effective, and have high load-bearing capacity. Their square design ensures stability and efficient drainage, making them popular in urban infrastructure.

How is the manhole cover kept clean during asphalt pouring?

To preserve the clarity of text and patterns, protective films or covers are placed over manhole frames during road paving to prevent asphalt from sticking.
