The manhole covers in Holon are generally made of metal or concrete , but there are also plastic (composite material) covers .
Their shapes include square , round , rectangular , or elliptical .
In many cases, when round covers are intended for sidewalks, they are set within a square frame to facilitate the paving work around them (these are, in fact, most of the square covers).

The covers in Holon are not colored. There is a relatively large number of gilded covers, mainly those produced by the manufacturer “Wolfman” .

Covers intended for the Holon Municipality usually bear the city’s emblem or the inscription “City of Holon” .
Many covers belong to the “Mei Shikma” water corporation, which serves the city of Holon .
In the Agrobank neighborhood, there are covers specifically designed for the neighborhood, bearing its emblem .

As in other Israeli cities, a relatively large number of covers in Holon belong to other cities (the “Bug” category), mainly to the city of Tel Aviv .
Also included in the “Bug” category are covers belonging to other water corporations, such as Tel Aviv’s “Mei Avivim” .

There are also covers intended for consumers that are not necessarily municipalities or local councils.
These covers are not tied to any particular city and can be found throughout Israel—for example, covers for Mekorot (the national water company) or for Ayalon Highways .

The purpose of the cover usually appears on it (water , sewage , etc.), so the number of covers in the “Unknown” category is relatively small.

A significant number of covers in Holon display their year of manufacture .

In general, the design of Holon’s covers is not distinctive and follows the standard patterns typical of each manufacturer. However, there are a few unique covers featuring a large city emblem .

Manufacturers
The manufacturer’s name usually appears on the covers. Most of the covers are produced in Israel by several leading manufacturers:
Menashe Baruch , A. Talitmacher , Vulcan Foundries , Gelem , and others.
It is rare to find covers made abroad, but they do exist, as can be seen from the list of manufacturers on this page (for example, one made by the large international manufacturer PAm ).

Standards
Manhole cover standards include those unique to Israel (the Israel Standards Institute mark and Israeli Standard 489, equivalent to the international EN124 standard ).
In addition, the international EN124 and its various load classes (A15–D400) are common.
Additional standards appear mainly on covers not manufactured in Israel.
