The certifications obtained over the years represent the company's commitment to continuous improvement.


The first certification dates back to 1997 and concerns UNI EN ISO 9001 (quality). Over the years, this was gradually joined by others, UNI EN ISO 14001 (environment), obtained in 2003 and those relating to the Chain of Custody of timber, according to the FSC® and PEFC schemes, achieved in 2005. In June 2010, the company was also certified according to the Ohsas 18001 Safety standards (later to become UNI ISO 45001) and in November 2010 it obtained the certification related to the CE marking of solid wood according to the UNI EN 14081-1 standards. In December 2022, it also obtained the certification related to the CE marking of aluminium according to the EN 1090-1 standard and the UNI EN 3834-3 standard, which set out the quality requirements for the correct management of the welding process for metal carpentry.
