Sisti Engineering & Officine Brevetti Sisti

Company

One story, two approaches to safety

For over sixty years, the name Sisti has been a leading name in the Italian fire safety and technical joinery sector. A story that began as Officine Brevetti Sisti and has now evolved into a modern, well-structured organisational model, capable of fully meeting the market’s needs.

In 2025, Sisti Engineering was founded, a company dedicated to the supply, design and development of products, whilst Officine Brevetti Sisti continued its operations, specialising in installation and certified maintenance. Two distinct yet perfectly integrated entities, working in synergy to offer a comprehensive and highly specialised service.

A story told with expertise and innovation

The company’s roots date back to the early 20th century, with steady growth leading, in 1968, to a key milestone: the first fire test certified in Italy in accordance with the regulations of the time.This milestone marked the beginning of a journey towards excellence, consolidated over time through more than 18 patents filed, around 53 national and international certifications, and continuous investment in research and development – which today form the foundation of an ongoing commitment to innovation and quality.

Certified quality

Two organisations, one goal

Thanks to these developments, greater specialisation is now possible:

Officine Brevetti Sisti

This structure enables us to oversee every project at every stage, from the initial technical specification right through to post-installation management.
