Our company was established in Concorezzo near Milan in 1961 by Antonio Calloni, who, after having gained experience in the mechanical industry, decided to start his own business producing pressure regulators for gas and equipment for welding and cutting metals. At the beginning of the sixties a company in Concorezzo started the production of the first modified bitumen membranes and soon after Calloni was contacted to design and produce equipment that would be used to install these innovative products.

Constantly developing and improving our products to meet the requirements of the market and our customers developing needs, we have become the company of reference for installers and resellers in the field of roofing and waterproofing equipment.

Our wide product range includes torches for roofing, waterproofing and roofing metalwork, pressure regulators for gas, special equipment used for new waterproofing methods, kettles for melting bitumen and torches for welding and cutting. All of them are designed and produced with the utmost attention to safety and quality, along with consideration for ergonomics, health and environment.

Thanks to a long experience and constant technological innovation, both of the products and of the production process, Calloni has become a leading company in roofing and waterproofing. It has reached professional success, both on the home and foreign market, in fact it exports in more than 50 countries all over the world.
