The manhole covers in Vietnam are typically made of metal or concrete and come in square , rectangular , or circular shapes.
In some cases, round covers are surrounded by square frames to facilitate integration with sidewalk paving .

Generally, the covers are not colored, except for a project in the city of Hanoi where manhole covers were transformed into colorful artworks as part of an initiative to beautify the city . No gilded (gold-colored) covers were found in Vietnam.

City emblems usually do not appear on the covers.

In many cases, the purpose of the cover is not indicated. However, sometimes it can be inferred from the name of the utility it serves, such as:

Drainage: CTY THOAT NƯỚC ĐÔ THỊ (Urban Drainage Company of Ho Chi Minh City) ,

Or from the text appearing on the cover, such as ĐIỆN LỰC (Electricity) on electric covers .

Manufacturers
Typically, the names of manufacturers do not appear on the covers. However, some covers can be found made by the local manufacturer Hapulico , or by the Spanish company Fabregas .

Standards
It is rare to find standards marked on manhole covers in Vietnam. However, since some covers are imported, you may encounter the European standard EN124 and its load class indicators (e.g., B125) , ISO 2531 , or the Spanish UNE standard .
