In 1994, Gamma was awarded UNI EN ISO 9002 certification and in 2003 the UNI EN ISO 9001 : 2000 , yet there is no doubt that the quality of Gamma products had always gone way beyond this, involving a level of customer care and customer satisfaction which pre-empted the introduction of quality systems by years.
For this purpose, the raw materials are acquired mainly from leading western European firms (in Germany, Spain and Italy) able to supply pre-certified materials.

It is as a result of this focus on the customer's needs that Gamma can boast a workforce that is continually striving towards improvement, with staff able to respond to specific requests.
The objective of resetting non-conform products is now within reach. The success achieved in more than 50 years of business is merely a point of departure for new and stimulating business goals, representing an impartial haven for customers in search of experience, speed and reliability.
