Historic Landmarks


Tempel Steel Co. arrives in Brazil

Tempel Steel Co., headquartered in Chicago (USA), arrives in Brazil. The following year it is established in Ribeirão Pires (state of São Paulo), in the same plant where Grupo Soma is located to this day.


Soma is born

Soma was born as a result of the purchase of the Brazilian subsidiary of Tempel Steel Co.


The largest lamination stamping

Soma seized the opportunities to nationalize previously imported electromagnetic steel laminations and cores. By investing in machines, processes and people, it became the largest stamping company in the sector in Brazil.


Start of aluminum injection operations

Soma remains strategic and an important milestone this year was the start of the aluminum injection operations. In 2006, the second building and manufacturing area was built.


A new company is born: Pro-Sol

Three Soma partners and three other businessmen found the solar heaters and collectors manufacturer that quickly became the leader in the HIS (Social Interest Housing) market.


Pro-Sol stood out in popular housing projects

In a short time, Pro-Sol has already gained prominence by participating in large popular housing projects, strongly pursuing this niche in the following years.


Soma becomes Grupo Soma by taking control of Pro-Sol

At the end of this year, Grupo Soma is formed with the acquisition of full control of Pro-Sol capital, unifying the company and having the same shareholding structure for both companies.


Pro-Sol is fully transferred to Ribeirão Pires (state of São Paulo)

Pro-Sol, which previously operated in the neighboring city of Mauá (state of São Paulo), is fully transferred to Ribeirão Pires (state of São Paulo) and to the new building built at the Group’s manufacturing plant.


Grupo Soma acquires Heliotek Termotecnologia

Grupo Soma acquires from Bosch, one of the major players in the solar heating systems market: Heliotek Termotecnologia. It therefore becomes the Bosch gas heaters distributor in the country.


The union of Pro-Sol and Heliotek results in the largest company in this sector in LA

The union of solar heating market companies resulted in the largest company in Latin America, in the increase of 3 thousand m² of manufacturing area, in the expansion of the product portfolio and strong retail presence.


What do we expect from the future?

In 2023, Grupo Soma will complete 25 years since the first company was founded. Our infrastructure has a total occupied area of 43.4 thousand m², of which 14.6 thousand m² is the manufacturing area, offices for around 260 employees, strategically located in the metropolitan region of São Paulo.
We believe in creating jobs, and we are committed to the preservation of nature, the use of clean energy and society.
