Manhole covers in Singapore are usually made of metal and are square-shaped

 

, rectangular

 

, or round

 

.

In Singapore, no colored manhole covers were found, except for those painted after production (such as gas covers, painted yellow

 

). Golden covers mark special events or malls

 

.

City emblems generally do not appear on covers from Singapore, but some feature famous buildings

 

or various illustrations

 

.

For many covers, their purpose is not immediately clear. On the other hand, communication covers are often identified by the name of the telecom company printed on them

 

; sewer covers may bear the word "sewer" (or its abbreviation)

 

; gas covers may have the word "GAS"

 

, etc.

Manufacturers
The name of the cover’s manufacturer is usually not displayed, but when it is, it often belongs to local manufacturers such as Chong Cheong

 

and Norika

 

, or international ones like Norinco

 

and PAm

 

.

Standards
Covers may feature the European EN124 standard and its associated load classes (D400, B125...)

 

, as well as the Singaporean SS30 standard

 

.
Covers may also bear standards from other countries, particularly those produced by international manufacturers.
