Storia - Apparecchiature antisismiche

The story of ALGA Group began in 1942 when Dr. Ing. Giuseppe Marioni and Dr. Ing. Pietro Noli, who are recognized as the inventors of the partial prestressing-technology, conducted a research program at the Engineering University of Zurich, with the technical contribution of Prof. Piero Colonnetti and Franco Levi and under the supervision of Prof. Ros. Those tests were to establish the feasibility of using high tensile wire as a pre-tensioning element for clay precast elements.

Two years later BIARMATO was founded, it was merged in 1956 with PREBETON CAVI that was the precursor and the company leader of post-tensioning technologies in Italy.
The experience gained in over 30 years especially in the field of superhighway building and bridges was merged in PRECO, which developed it's own post-tensioning system and extended the activity to all branches of civil engineering fields.
All previous activities have been merged in ALGA which was founded by merging the above mentioned companies keeping the high experience and know-how of the staff.

ALGA has operated in the field of structural engineering for more than 50 years, being primarily known in the sector of bearings, expansion joints, post-tensioning and antiseismic devices. Today ALGA is managed by Dr. Ing. Agostino Marioni, who is also the chairman of the European Technical Committee for the standardization of structural bearings (CEN – TC 167).

Design, production and installation are performed in compliance with a quality system according to UNI EN ISO 9001, certified by IGQ. Alga has about 100 skilled collaborators including qualified engineers, technicians, assemblers and mechanics.
