Round ductile iron manhole covers are essential components for protecting urban underground pipe networks. These durable covers are designed for public infrastructure including municipal roads, residential areas, industrial parks, airports, and ports. Their exceptional strength, corrosion resistance, and load-bearing capacity make them ideal for safeguarding underground utilities such as water supply, drainage, electricity, telecommunications, and gas systems.
Manufactured from high-strength ductile iron through precision casting, these circular covers prevent positioning deviations caused by vehicle traffic while enhancing impact resistance. The surface features anti-slip and anti-corrosion treatments to ensure safety for pedestrians and vehicles while extending product lifespan.
