With you since 1968

The company was founded in 1968 by two visionary young entrepreneurs: Giovanni Maturi and Francesco Sampietro. Over the years the company grew and moved from Massagno to Mezzovico, consolidating its presence in the Ticino market.

In 2013, Mr Francisco Sampietro took over the management, thus guaranteeing the continuity of the values already passed on by the two founding partners. Today, our company covers a total area of 4150 square metres, consisting of 2 production halls dedicated to iron and aluminium processing and 1800 square metres of yards.

Our team, consisting of 42 specialised employees, is supported by state-of-the-art technology to realise high-level metal constructions.

Fire fighting systems

Our fire wall systems are able to meet all fire protection safety requirements.

The main purpose of a partition system is to minimize the effects and consequences in the event of the spread of flames and smoke. This is primarily about the prevention of personal injury, but it also involves limits to the property damage that may result.
