Lorenzetti History

Our History

At the end of the 19th century, the civil engineer Alessandro Lorenzetti embarks at the Port of Genoa, Italy, bound for Brazil, where he came to work in projects at the Port of Vitória, in Espírito Santo, and at the Santos - Jundiaí Railway, in São Paulo . He remained in Brazil for several years, returning to Italy at the beginning of the 20th century.

During his time in Brazil, Alessandro Lorenzetti met Carlo Tonanni, with whom he established a partnership, in 1923, of the Tonanni & Lorenzetti foundation. The building was located at Presidente Wilson Avenue, Mooca neighborhood. This area had the most industries of the city and the small factory started only with four employees and four automatic lathes, with their goal by manufacturing precision screws for many utilities.

A few months later the company's activities started, his sons Lorenzo and Eugênio arrived in Brazil, together  continued the work started by his father Alessandro, creating the foundations of what is today one of the largest manufacturers of metal sanitary ware and household appliances, Lorenzetti S.A. Indústrias Brasileiras Eletrometalurgicas.


20s and 30s: Pioneering

The Lorenzetti brothers quickly increased the number of customers and the product lines, manufacturing screws, pins and axles and, at the end of the decade, parts for industrial machines. As a result of the good work they performed, in a few years, Eugênio and Lorenzo acquired the share of partner Carlo Tonanni.

In the 1930s, they expanded their operations in the metallurgical sector, throughout the manufacture of metal accessories for curtains, restaurant trays, sugar bowls, cruets, brass vases, among other products. Under license from an Italian company, the company also started importing and selling electrical equipment for installations.

In the following years, Eugênio and Lorenzo continued to expand their businesses, with the new corporate name Lorenzetti and Cia, remaining attentive to the needs of the time and seeking quick and innovative solutions, making the company a pioneer in the production and commercialization of various products. It was in this context that skates and lighters were produced, among other products.

During the 1930s, the company develops and manufactures porcelain disc insulators and hardware for power transmission lines and innovates by manufacturing for the first time in South America the resin known as "bakelite", used for the manufacture of electrical material for domestic and industrial installations. It was also the first in Brazil to manufacture electric motors up to 100HP.

40s: Adaptation and diversification

The World War II brought huge challenges for the company, which, despite the difficulties, knew how to take advantage of the opportunities and emerged strengthened from this difficult period. Due to the scarcity of gasoline, Lorenzetti manufactured devices that used coal as an energy source to run engines. This equipment, known as gasogen, was installed in automotive vehicles.

With the drastic decrease in maritime trade, it started to manufacture the electrical materials that mattered: switches, keys, lamp holders, fuses, etc., becoming the largest factory of low voltage electrical materials in Latin America.

It also manufactured parts for automobiles, in particular spark plugs of the “LOZ” brand. Started the production of high-pressure hydraulic pumps and drawn steel. At the end of the decade, the company expands commercially throughout South America.

50s and 60s: The electric shower

In that decade, a major milestone of Lorenzetti history, which started production of the automatic electric shower - household appliance, which was the company's main product in the 50s. With the successful launch, the line was expanded with the production of electric taps and heaters.

Looking towards the future,  the company started on the 60's expanding the business through industrial and commercial market by manufacturing new appliances and high voltage materials, such as floating pumps for wells, fans and electric irons.

It also started the production of capacitors for starting motors, for radio and TV and for power factor correction.

70s and 80s: Electricity technology

In the mid-1970s, Lorenzetti launched its first electric shower head made of engineering thermoplastic, starting a new generation of household appliances, which combine quality and affordable price, and complement the line with the production of flush valves.

The company deeply entered in the production of heavy-duty, high-tech electrical equipment, such as high-voltage insulators, disconnect switches and SF6 gas circuit breakers up to 800,000 volts.

It designed and produced fuse switches of up to 32,000 volts, used in electric power distribution lines, becoming the largest manufacturer of this equipment in Brazil. At the plant located in the state of Santa Catarina, it manufactured engine control centers and control panels.

All hydroelectric plants built in Brazil by then,  such as Itaipu, Tucuruí, Xingó, among others, own Lorenzetti’s equipment.

The engineering division of the group designed and built electrical substations for industrial and large consumers.

90s: The reinvention

The 1990s marked the reorganization of the company's activities. Efforts was based on creation, production and sale of appliances for residential use. More and more the brand differentiates by the product quality and solutions offered. The company expands its activities in the country and in the world and launches the first electric showers with electronic control and built-in pressurizer.

Jet Turbo
