The covers in Sirmione are usually made of metal

 

and are square

 

or rectangular

 

in shape.

No painted or gilded covers were found in Sirmione, nor were any covers bearing the city emblem.

On most covers the consumer’s name does not appear, except for covers intended for the electricity company Enel

 

and for the Municipality of Sirmione

 

.

The purpose of the covers is determined by the consumer name (ENEL – electricity

 

), the drainage slots (drainage

 

), or by the text appearing on them (FOGNATURA – sewer

 

).

There is no distinctive local design for covers in this town; they are generally designed in the typical manner of the manufacturer.

Manufacturers
The covers were made by the Italian manufacturers Montini

 

, Fonderie Silvestri

 

and other manufacturers from the same country.

Standards
The common standards are the European standard EN124

 

and its associated load classes (C250–D400)

 

. The Italian IGQ

 

and UNI

 

standards can also be found.
