Sira Group was founded on the extraordinary insights, values and principles of its founder, a tenacious and gifted man who managed to combine the consistency of his beliefs with the many radical changes he faced in over 60 years of work experience, all thanks to the strength of his ideas and dedication to the job. It is this lesson that today continues to constitute the backbone of the group: a shared heritage of life, values, work and ethics.

The group was officially founded in 1959, starting with the first foundry producing aluminium alloys, bronze and brass, but the turning-point of the company occurred with the development of the revolutionary worldwide patented aluminium radiator in 1961. This technology, developed completely inside the company, improved over the years and started to replace old and traditional cast iron radiators. This patent has proved to be an extraordinary innovation and a real milestone in the field of home heating.

Sira® products are designed and manufactured with a special focus on environmental issues: the whole production process adopts special measures to reduce exhaust emissions, especially during the phase of painting, which completely eliminates the emission of polluting substances. Each production process, equipped with as many as 14 QCS (Quality Control Step), is subject to strict quality controls. Sira® products are manufactured using the most modern techniques to provide best performances with the lowest power consumption. Elegance, versatility, safety, power and environmental comfort are just some of the main qualities that the Sira range of Aluminium radiators possess.
