From handicraft to industry, a long way started in 1871...


It was in those times that Ambrogio Tenconi started his work as a blacksmith in Airolo, to coincide with the excavation of the railway tunnel under the St. Gotthard.

His sons Faustino and Guglielmo went on with their father's activity, which was taken up and expanded later by Fausto and Edoardo, who gave the company the name Fratelli Tenconi in 1943, a firm that had the aim of running a workshop for steel constructions.

In 1974 the company turned into a Limited company, gaining more and more industrial characteristics. After the two brothers' death its name was changed into TENCONI SA and in 2001 the company was further expanded with a new mechanical workshop in Gordola.

TENCONI SA was certified in 1995 according to Quality standards ISO 9002 and, since 2001 in accordance with ISO 9001.

Actually we are proud to be in possession of the following Welding certificates:
- EN ISO 3834-2
- DIN EN 15085-2 CL1
- DIN 18800-7 Class E
- H2 SN 505 263/1
