that the founder instills in its business, the BEM canthrive despite

the years of World War II.

Ambrogio immediately surrounded himself with professionals designer that trigger

his curiosity and his desire to innovate, bringing the BEM to grow,

and to create products to the limit of the 'unthinkable.



The BEM over the years has collected numerous and notable collaborations, among them

flameproof panels made for the National Hydrocarbon Corporation, the electrical

system of the ENEL 4 stations cableway to lake Desio in Sondrio and the laying of the

electromagnets 92 Kg on railway points of Milan's central station.

In addition, the company has worked closely with other companies, in the form of a

supplier,such as the Demag for which the BEM realized switches for electric hoists,

FIAT which gave knobs hanging hoist or the Gutter that relied on family Balzarotti

the installation of electrical systems of their machines.

There are also international experiences such as the construction and installation on

behalf of Stigler Otis of various control panels for lifts in Alexandria.

giving rise to the ideasof customers.

Under the brand MR the company also produceswindings for the industry, single-phase and

three-phasetransformers, auto-transformers and reactors to customerspecifications and electromagnets

standard and custom. Even today, the brand continues to developfuturistic technologies collaborating with

the best Italian and Europeanindustrial companies, creating projects of great importance, such as the 

execution of the control panels and systemsfor solar tracking technology with Stirling or the realizationof

a set of compact machines for stuffing.


Under the brand Baglem® Light Led comes a line of products for professional use for lighting and

signaling construction sites, construction cranes fixed and mobile obstacles on the fly, boats and service
