The manhole covers in Rosh HaAyin are generally made of metal
or concrete
and are round
, square
or rectangular
in shape.
In many cases, when round covers are intended for sidewalks, they are surrounded by a square frame, which greatly simplifies the paving work around them
(these are essentially all the square covers found on the site).
The covers in Rosh HaAyin are not colored; however, there is a relatively large number of gold-tinted covers, mainly those manufactured by the producer “Wolfman”
.
Covers intended for the Rosh HaAyin Municipality usually bear the municipal emblem
.
Many covers are intended for the water corporation “Ein Afek,” which serves the city
.
The purpose of the cover generally appears on it (water
, sewage
, drainage
, etc.), and therefore the number of covers in the “unknown” category
is relatively small.
The year of manufacture appears on many of the covers in Rosh HaAyin
.
In general, the design of the covers in Rosh HaAyin is not special and matches typical designs of the manufacturer.
Manufacturers The manufacturer’s name usually appears on the covers. Most covers are produced in Israel by several leading manufacturers – Menashe Baruch
, Gelem
, Wolfman
and others.
Standards The manhole cover standards include standards unique to Israel: the Standards Institute of Israel conformity mark
and Israeli Standard 489 (equivalent to the international EN124)
.
In addition, the international EN124 standard
and its various load classes (B125–D400)
also appear.
