The covers in Budapest are made of metal or concrete and are rectangular , round , square or elliptical in shape. Additional cover shapes include ones resembling a refuse-collection scoop , hexagonal or octagonal .
In many cases, when round covers are intended for pavements, they are surrounded by a square frame, which greatly facilitates the paving work around them .

No coloured covers were found in Budapest, but there is a relatively large number of gold-tinted covers .

Covers intended for the Budapest municipality or its related bodies (such as the sewer department – FCM) usually bear the city emblem .

The intended purpose of the cover is often shown: water (the letter W, or the word VIZ ), drainage covers are identifiable by their drainage slots , sewer covers bear the name of Budapest’s sewer department (FŐVAROSI CSATORNÁZÁSI MŰVEK) , and so on.

Sometimes the year of manufacture appears on the covers .
