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.
