A cast iron manhole cover
is a cover for drainage channels, sewers, or underground utilities (cables/pipes) made of cast iron. Known for its strength, durability, and ability to withstand heavy loads, this component consists of a frame and cover and is often used on highways, sidewalks, ports, and industrial areas. Manholes are commonly used in urban infrastructure projects, bridges, airports, housing, and industrial areas.
One of the functions of a manhole is as a complementary structure to the wastewater drainage system. It serves as a place to inspect, repair, and clean the channel from accumulated debris and objects caught during flow, as well as to connect several channel branches, both at the same or different heights.
The manholes we manufacture are round and square, with hinged and non-hinged designs. They are available in standard, medium-duty, and heavy-duty versions. Round manholes range in diameter from 30 cm to 100 cm, and square manholes range in size from 40 cm to 100 cm. We can also create custom sizes and designs according to customer requests.
Medium-duty manhole covers have a thickness of approximately 1 cm, while heavy-duty ones have a thickness of approximately 1.5 cm. These can be customized to customer requirements. We can also create custom cast iron manhole covers based on tonnage, load capacity, or size.
We can also create custom cast iron control tank covers according to customer requests.
These manholes are commonly used in urban infrastructure projects, bridges, airports, housing complexes, and industrial areas.
