The manhole covers in Herzliya are usually made of metal or concrete , though there are also plastic (composite) covers .
Their shapes include square , round , rectangular , or oval .
In many cases, when round covers are intended for sidewalks, they are surrounded by a square frame, which greatly facilitates the paving work around them (these are, in fact, most of the square covers).

The covers in Herzliya are not colored. A relatively large number of golden-toned covers exist, mainly those produced by the manufacturer “Wolfman” .

Covers intended for the Herzliya Municipality usually bear the city’s emblem or the inscription “Herzliya Municipality” .
Many covers belong to the water corporation “Mei Herzliya,” which serves the city of Herzliya .

As in other cities in Israel, a relatively large number of covers belonging to other cities have been found (the “bug” category) .

There are also covers intended for consumers who are not necessarily municipalities or local councils. These covers are not tied to a specific city and can be found throughout Israel — for example, covers for Israel Railways (which in this case is not located near a train station – “bug” category).

The cover’s function is usually indicated on it (water , sewage , drainage , etc.), and therefore the number of covers in the “unknown” category is relatively small.

A significant number of covers in Herzliya display the year of manufacture .

Generally, the design of Herzliya’s covers is not unique and corresponds to designs typical of their manufacturers.

Manufacturers
The manufacturer’s name usually appears on the covers. Most are produced in Israel by several leading manufacturers – Menashe Baruch , A. Telitmacher , Yitzikat HaMifratz , and others.
There are also covers from non-Israeli manufacturers, usually drainage covers, such as one made by the Greek producer Nicoll .

Standards
The manhole standards include those unique to Israel (the Israeli Standards Institute mark and the Israeli standard 489, equivalent to the international EN124 standard ).
In addition, there are the international EN124 standard and various load classifications (A50 - E600) .
Other standards appear mainly on covers that were not produced in Israel.
